I am not a 'PHP guru' and I dont know where you can find an algorithm but:-

If the only problem is users adding/not using name extensions, then for your
company exists already test you could remove known extensions from the input
company name - ltd, plc, etc - and replace this with a wildcard for the
check.

eg. SELECT id FROM table WHERE name LIKE '$input_name_without_extensions%'

Sorry this post is OT. I think name matching is quite a problem, I've
never found a foolproof way around it. Debbie's answer is good for the
question you ask, but still many cases fall through. In the UK, "British
Telecom" years ago changed its name to "BT" but both get used. "Post
Office" changed its name to "Consignia" and now back again to "Post
Office". Then one company buys out another e.g. "Foo Ltd" buys "Bar
Ltd". I don't think you should go by the name alone.

Use the post/zip code too. In the UK, a street number (or name) plus the
postcode is unique to a building (though it does not help with several
companies/appartments in the same building). The post/zip code matching
will not help with companies with more than one site.

Hi,

1. you might start by removing things which are common problems... make
everything lowercase, uppercase, uppercasewords, etc etc (if not permanent,
just for comparison). You may also strip out leading and trailing
whitespace, multiple spaces, etc etc. You may choose to remove LTD, PTY,
GMBH, etc (and all variants) from the string too.

2. you might want to check out the functions that compare the similarity of
two strings in a few different ways, for a few different uses. My guess is
you'll want similar-text() or levenshtein():

http://www.php.net/manual/en/function.levenshtein.php
http://www.php.net/manual/en/function.similar-text.php
http://www.php.net/manual/en/function.soundex.php
http://www.php.net/manual/en/function.metaphone.php

Check out the manual's string section, which is where I found all this :)

Cheers

attached mail follows:

Assume you've got some class that has one or more classes inherited from it.
The parent class has a function that is normally called using the ::
operator (a class function). Assume also that the class function is never
called from an object function. Is it possible to find if the class
function was called on the parent class, or on the child class?

example:
Class A has a function foo(), callable by A::foo(). Class B extends A. If
outside code makes the call B::foo(), can you tell from within foo() that
the function was called on B and not A?

I think this is impossible but I want to confirm that suspicion. It's
important that the call B::foo() isn't made from inside any object function,
so that there's no context for the $this variable; the get_class() function
isn't applicable.

attached mail follows:

I think I know what you mean. You could get it to return the name of the
class.

eg.

class A {
    function foo () {
      return get_class($this);
    }
}
class B extends A {
}
class C extends A {
}

  $a = new A();
  $b = new B();
  $c = new C();
  print $a->foo();
  print $b->foo();
  print $c->foo();

Is this what you mean?

not quite... the case I'm interested in is this, given your example:

print C::foo();

which would print nothing, unfortunately, since when the function is called
using the :: operator there is no $this variable. basically what I'm
looking for is a replacement for get_class($this) when the function is
called using ::

I dont understand what you are saying then or what you are trying to do.

How can you call C::foo() outside of a class? You access class functions
externally with ->

attached mail follows:

when you call a function with ->, you must call it on an object ($c->foo(),
for example). the function is termed an "object function" when used that
way. php has an operator :: that enables that same function to be called
without a specific object; in this case, I'm referring to it as a "class"
function. another term for this is usually "static" function. any function
of a class can be called in both ways. the only catch is that, when called
as a class function, the function can't in turn call any functions on $this
or a fatal error will result.

sorry this is so confusing, I probably should've used the term "static" from
the beginning.

"I probably should've used the term "static" from the beginning." <- maybe

The mistake is mine not yours. I know about the :: operator I use it all the
time (but within classes parent::function() etc) - but I never realised
until now that PHP will let you use any class before instantiation (and
nearly all my PHP work uses classes). I have never even attempted to try it
because in all other languages I know trying to use an ordinary class before
instantiation will just result in a null pointer error or the equivalent of
one.

PHP OOP is different I know, one big example is that there is no provision
for data encapsulation - one of the main objectives of OOP, neither can you
differentiate between types of classes/methods (which is probably what is
causing the confusion).

Now it seems it is even more different than I thought. All I can say is
mmhh.......

Most OO languages allow static method calls. C++, Java, Python, Ruby,
etc. PHP may have some OO differences, but this is not one of them.

PHP allows static method calls... But back to my original question...
inside a method that has been called statically, can I determine for what
class the method was called? Again, obviously the question is only
applicable if there is some inheritance involved, and the child class does
not declare the method in question. Below is my original example spelled
out in code... the call to get_class is not valid since there won't be a
$this variable in the context of the static method... Can I replace it with
something that will cause it to echo "B"?

Class A {
function staticFunc() { echo get_class($this); }
}

Class B extends A {}

B::staticFunc();

Since static method calls are completely disconnected from any class

which is what I suspected... thanks for confirming. and yes, the call is
disconnected from any class _instance_, but not from any class. as you said
before, PHP has some OO differences from java, etc, and this is one of
them... if you had static members, then methods called statically would have
to know on what class they were called. anyway thanks again

...and to deal with some (but not all) proxies:

$ip = (getenv("HTTP_X_FORWARDED_FOR"))
? getenv("HTTP_X_FORWARDED_FOR")
: getenv("REMOTE_ADDR");

Either way you're still going to get stuff that isn't right, so make
sure
(a) you validate the contents of $ip before doing anything with it, and
(b)
you're not using it for anything critical.

For a coursework assignment I have to investigate this thing where you do the following for example:

264 - Choose 3 digits that are not the same 12 - Find the sum of them.

264 246 624 642 426 462 - List all the possible combinations of those digits _____ 2664 - Add the combinations

2664 / 12 = 222 - Divide the answer by the sum of the three digits and you allways get 222! To speed up the process of finding any exceptions if any, I thought id use php to do this, however i get a problem, the script runs without any coding errors, but it doesnt do what i want it to do - instead of returning any three digit combo that doesnt return 222, it just prints EVERY combo whice passes my conditional statement to weed out numbers that have digits where 2 or more are the same.

Here is my code:

<?php

for ($i = 012; $i < 987; $i ++) {

$comma = chunk_split($i, 1, ","); $split = explode(",", $comma);

if ($split[0] == $split[1] || $split[0] == $split[2] || $split[1] == $split[2]) { } else{

$digitstotal = $split[0] + $split[1] + $split[2];

$num1 = "$split[0].$split[1].$split[2]"; $num2 = "$split[0].$split[2].$split[1]"; $num3 = "$split[1].$split[0].$split[2]"; $num4 = "$split[1].$split[2].$split[0]"; $num5 = "$split[2].$split[0].$split[1]"; $num6 = "$split[2].$split[1].$split[0]";

$numtotal = $num1 + $num2 + $num3 + $num4 + $num5 + $num6;

$answer = $numtotal / $digitstotal;

if ($answer != 222) { echo("$i does not return 222! "); } } } ?>

What is wrong with it? Any help at all is greatly apreciated.

attached mail follows:

Well, since it's for school I'll only point out a couple of issues...

- your for loop will never test the number 987 even though it should.

- add the following line rightr after you compute $numtotal:

print("$numtotal = $num1 + $num2 + $num3 + $num4 + $num5 + $num6\n");

and you'll see that you'll get output like:

28.6 = 2.6.5 + 2.5.6 + 6.2.5 + 6.5.2 + 5.2.6 + 5.6.2

which should help you understand why it's not doing what you think it's doing.

good luck.

> What is wrong with it? Any help at all is greatly apreciated.

Consider the differences between my code below and yours. And as far as I can see, there's no combination higher than eleven, lower than 987 which doesn't work out.

<? for ($i = 12; $i < 987; $i++) {

$newI = $i;

settype($newI, "string");

$newI = str_pad($newI, 3, "0", STR_PAD_LEFT);

$digits = $newI[0] + $newI[1] + $newI[2];

$num1 = $newI[0].$newI[1].$newI[2]; $num2 = $newI[0].$newI[2].$newI[1]; $num3 = $newI[1].$newI[0].$newI[2]; $num4 = $newI[1].$newI[2].$newI[0]; $num5 = $newI[2].$newI[0].$newI[1]; $num6 = $newI[2].$newI[1].$newI[0];

$sum = $num1 + $num2 + $num3 + $num4 + $num5 + $num6;

$answer = $sum / $digits;

if ($answer != "222") { echo $i." does not fit in the scheme."; }

} ?>

Hi,

I am trying to upgrade my script which currently uses globals (and register_globals=on) to turning that flag off. The online documentation on register globas has the following code recommended by users in order to register the variables:

$GLOBALS["dbname"] = "dbname";

//register globals foreach ($GLOBALS as $key=>$val) { if ($key !="GLOBALS') { eval("\$$key = '$val';"); } }

I am using the global array to connect to my database. I find that if I insert the code above, I get an error message that the document contains no data. Can anyone tell me why? Perhaps I would be better off just declaring the variable? Would that take care of the problem?

$dbname= "dbname";

Thanks,

Nicole

I want to keep track of referers to my site. I want to store the domain name of the referer in a db field. I want 'just' the domain name, not the full url.

So I need a snippet of code that could parse the $HTTP_REFERER, and return just the domain name.

Example....

1) http://www.google.com 2) http://www.google.com/ 3) http://www.google.com/search?sourceid=navclient&q=evil+microsoft

... would all give me http://www.google.com

Could anyone give me a hand? Thanks!

I have the following line in a program I'm working on:

$query = "UPDATE countertable SET CurrDate = '$ndate' WHERE ID = $id"

$ndate is a properly formated date read from a text field on a form on the previous page. When I run the query using mysql_query, it returns TRUE each time, but the field is not updated. The only explanation I can think of is that there is something wrong with the date value. I've echoed it to the screen and it looks fine, but the query still doesn't work. Any suggestions?

Thanks in advance,

Brad

When you say it looks fine, are you meaning it looks like 2002-10-02?

Are you actually running the query somehow? Like with mysql_query()? Since you didn't deliver more code it this is the guess I would take.

$query = "UPDATE countertable SET CurrDate = '$ndate' WHERE ID = $id" ; // do some error checking if(!($data = mysql_query($query, $your_bd_connection))){ print("MySQL reports: " . mysql_error() . "\n"); exit(); }

Hi,

it's a great tip to install PhpMyAdmin - or phpPgAdmin for PostgresSQL - this will only take you at most half an hour even for a newcomer.

You can then easily test queries, see any error messages and see what result they have on tables.

In this case I'd echo out the query

echo $query = "UPDATE countertable SET CurrDate = '$ndate' WHERE ID = $id"

and try to cut-and-paste it into the query-field in PhpMyAdmin.

When you say "nothing happens" you'd probably discover that ID is a number not matching anything _or_ that $nDate and the field are not proper date values ;-)

Hope it helps!

Now that I have the values in an array I would like to pull out the five highest and the 5 lowest. Is there a way to do that....if not, is there another way to do what I am looking for.

Hello,

how can I use global variables in my web portal? I have read the php documentation, but it works only in the same file. I want use more global variable on many php site.

For example: In login.php I use the code

$first=mysql_result($result,0,"FIRST_NAME");

and I want to print this $first variable all of my php site.

Thanks!

attached mail follows:

As far as I know there is no way to set a site-wide global from within a script. Use PHP Sessions or set a Cookie and then print the variable in any script you want by calling $_SESSION['first'] or $COOKIES['first'];. But you'll need a starting point for your visitors in order for this to work.

If your visitors will be accessing scripts at random you can do an include("setfirst.inc"); at the top of each script, where 'setfirst.inc' accesses the database and sets the $first variable each time a script is called.

You can't. You can, however, have a config.php or type page that's include()'d on every page in your site where you define these variables. For things like this that you draw from the database, it would be a good idea to query once and add to the session.

I find it useful to use something like a $_CONF[] array.

$_CONF['user'] = 'user'; $_CONF['path'] = '/home/user/htdocs/';

etc...

Easy, use one script for your whole site.

There is nothing that drives me more nuts than to encounter an application whose developers have left town and run into global variables. I don't mind file scoped variables so much, but to make a variable global across an application can drive one nuts when trying to debug.

That said, I do use global variables but they are from a class whose 'object' is global. I don't have 3000 php files running all over my site as I've seen done. I have just a couple of *handlers* that use classes and I have one class which creates my global array which is shared. It's very easy to trace variables.

I'd be very careful before I began to make variables global without some EASYmeans of tracing them. And it gets real interesting when one file inherits another which inherits another and in any one of them the value of your global variable can be changed. Does anyone know a good way for tracing such things?

If you are wanting it to be 'global' for the same visitor across your site use php session functions.

Hi,

I need to do either an insert or update into a MySQL table. Insert if there are 0 records or update if one record exist:

This is my code snippet:

if (mysql_query("SELECT COUNT(*) FROM AuthNum") == 0) { mysql_query("INSERT into AuthNum (FirstNum, LastNum, NextNum) VALUES (1,2,3)",$dblink); } else { mysql_query("Update AuthNum Set FirstNum = 1, LastNum = 2, NextNum = 3",$dbLink); }

My problem is, a record never gets inserted because the SELECT COUNT query is returning a resource ID of 2. How can I get the actual number of records in the table?

This won't work because a SELECT COUNT(*) query always returns a row, even if it returns zero as the value.

$result = mysql_query("SELECT COUNT(*) FROM ... "); $count = mysql_result($result,0);

so why not take that resulting row, and then do an if on it to see if the value is a zero? an extra step, but it would work

It is a Flash site that uses PHP for dynamically updating text in some text fields. If I can direct you to the Stallions menu---pick a horse. A page should load that has a picture of a horse on the left hand side and a green box on the right. The box on the right is dynamic text field. There should already be text inside of it.

I see it. My 4 other PCs see it. About 5 people on this list can see it. A dozen of my friends can see it. The guy at tech support for where this is being hosted can see it. My client can't see it on his PC running IE5, but can see it on his Mac. His girlfriend can't see it, but one of his friends can.

We had a fully working version up on a host that ran the PHP from Apache and everyone can see it. The site (and scripts) are now on a server that runs the PHP as CGI. It boggles the mind. Has anyone EVER heard of such a thing?? Are there security settings on the browser that won't let a CGI script execute, even from Flash?? Already made him clear his cache. Any ideas?

Check ur php.ini, there are settings to display showing absolutly any error, warning, and message. they are probaly set to not show them.

error_reporting = E_ALL & ~E_NOTICE

thats what i use, only displays what i need

Shot in the dark that may or may not help... Look into display_errors and log_errors. I think those are the names. They control where error output goes.

Cheers, Rob.

Yes,

On both my development machine and implmetation machine i have the same error_reporting. error_reporing = 2039 (that is what phpinfo() gives me ) is equivalent to E_ALL^E_NOTICE. And still i cant seem to get any error, even on a winxp system running Apache and PHP 4.2.1 (from the php.ini file) -

error_reporting = E_ALL & ~E_NOTICE

I still cant understand why PHP is not complaining ?

thx

gamin.

attached mail follows:

I noticed that by default, my display_errors was actually OFF, and the only way to see my errors was through Apache's error.log file

I don't know if that's already been checked, but... figured I'd try to help.

Hi!

I had PHP compiled with the "--with-mcrypt" option. So, when I use this script, PHP spit out the error " Warning: could not open encryption module" but it work fine if I use other script like "$SSL_CIPHER_USEKEYSIZE".

--clip-- mcrypt_module_open(MCRYPT_TripleDES, "", MCRYPT_MODE_ECB, ""); --clip--

Why is that? The mcrypt is already compiled with PHP.......

Hi,

My hosting provider still using CGI as Server API. I think this is way too much dropped behind. On my own development server I use Apache as Server API. However, maybe this could be a kind of consideration for the situation that multi-sites hosted on one server? I am thinking I'd better learn something before I ask my hosting provier. Thanks!

I'm getting much closer to achieving my goal here. Now, I'm missing yet one more element. Here is my code:

---------- $filename = "newexample.html";

$fd = fopen ($filename, "r");

$contents = fread ($fd, filesize ($filename));

preg_match_all('{\/*[A-z0-9_/-]+(.gif|.jpg)}', $contents, $matches);

for ($i=0; $i< count($matches[0]); $i++) {

echo "matched: ".$matches[0][$i]." \n";

$blah = basename($matches[0][$i]);

$contents = eregi_replace('\/*[A-z0-9_/-]+(.gif|.jpg)', $blah, $contents); }

print $contents;

fclose ($fd); ----------

In this PHP script I am reading in the contents from "newexample.html", going through it and looking for image strings ("something/.../imagename.gif|jpg"), and stripping them down to their basenames ("imagename.gif|jpg"). What I must ALSO do is print the contents of the html file with the new, stripped down image strings. What's going on in the above code is that each time you get to:

$contents = eregi_replace('\/*[A-z0-9_/-]+(.gif|.jpg)', $blah, $contents);

it goes through the entire html file and replaces every image string with the same replacement, so when the script is done executing, every image string in the html file is identical. Of course, what I *want* to do is replace them all individually. So if the html file has:

I want those strings to be replaced with:

But, the code as I have it is just replacing them all with <img src="imagename3.gif"> since it was the last one to have matched.

How might I go through and replace them one by one? Obscure hints are welcome. :)

Thanks, Jen

> I am the webmaster of the site, i pay for the server space, > is that what you mean?

First up Simon, I deleted over a hundred lines of no longer relevant content from your message including things like signatures. You should probably trim messages down when you reply to them...

Next up, when you say you are the webmaster, what does that mean? What sort of access do you have to the server? Can you connect to the server using ssh? Or do you only have access to uploading files using ftp? If the former, you can check permissions (which is almost certainly where your problem is) and act from the information you find. If you don't have ssh-style access then you'll likely be stuck with work-arounds to make things like this do what you want.

Do you understand the concept of users, groups and permissions? This is a *nix thing that is not as common on Windows platforms but is of critical importance when you start looking at issues like file creation, particiularly in automated scripts, on a *nix box. If you understand them then I won't bother going further, if you don't then this is probably where your starting point needs to be so that you understand why the problem is occuring and will be able to deal with it in future situations that you'll almost certainly run into.

Oh, and if you have ssh-style access then the ftp thing you're trying to do in php should really be done in other ways - the BoM web servers are loaded enough without receiving a hit every time someone loads your page.

CYA, Dave

I am having problems with arrays. I guess I just don't understand them all that well. I have an simple array of stock tickers. Then for each ticker I go to Yahoo to get their current price and try to push the Name of the ticker and it's value into an associative array(I think). Then I want to sort the array so the the values are in order from highest to lowest, so I can see the highest amount as the first position and the lowest as the last position.

Here is my problem; for debuggin purposes I do a print_r(array_values()); and I get the following for output. Array ( [0] => 7.28 [1] => 5.20 [2] => 1.969 [3] => 59.63 [4] => 4.43 )

I am not sure why I am getting this. I guess I expected the numerical positions to be the keys something like: Array ( [ikn] => 7.28 [xrx] => 5.20 [danky] => 1.969 [ibm] => 59.63 [rhat] => 4.43 )

Since I am not getting the results I expected I am not sure if the rest is working correctly because I do not know how to access the first position in the array, or the last. When I get this working, I will be adding 200 tickers and I would like to get the first 5 and the last 5, expecting them to be the highest 5 and the lowest 5 respectively. I hope someone will take the time to halp me.

Thank you in advance.

Here is the code I am working on:

$Tickers = array("ikn", "xrx", "danky", "ibm", "rhat"); $TickersCurrent = array();

foreach($Tickers as $Ticker) { $LookupUrl = "http://finance.yahoo.com/d/quotes.csv?s=$Ticker&f=l1&e=.txt"; $Current = implode('', file("$LookupUrl")); $Current = rtrim($Current); $TickersCurrent["$Ticker"]=$Current; }

// Done for debuggin only print "<pre>\n"; print_r(array_values($TickersCurrent)); print "</pre>\n";

asort ($TickersCurrent); reset ($TickersCurrent);

echo "CTC Indice = " . array_sum($TickersCurrent) . " \n";

echo "The highest Stock is $TickersCurrent[0]";

attached mail follows:

It looks like your problem is simply in the debug line, where you echo print_r(array_values($TickersCurrent)); You shouldn't call array_values() before print_r(), since array_values generates an indexed array of only the values (quotes), not the keys (tickers), of the supplied array, essentially taking your quotes from your ticker=>quote pairs and replacing the tickers with an index. Just do print_r($TickersCurrent) and you'll get the desired result. Hope that helps, Andy
