well, you could load lynx, then type "G" (go) and
type in "www.php.net" on the address bar, then
navigate your way to the download page from there.
(it's only one page deep into the site)

that's how i did it at work on our linux machine.

this is how you'd do it, in any of three ways,
depending on the values you want to start/stop with.

//counts from 0 to 10
$count=0;
while ($count <= 10) {
echo "$count, ";
$count++;
}
print "<BR>";

//counts from 1 to 10
$count=0;
while (++$count <= 10) {

//counts from 1 to 11
$count=0;
while ($count++ <= 10) {
echo "$count, ";

The special character I'm concerned with at the moment is the back tick ` which mysql doesn't like on an insert. I was looking for a way not to parse the entire file evertime I inserted or extracted them from the database. Its simple enough todo in perl and php just seems like it would burn alot of cpu time.

I was actually hoping mysql would have a way to encode it on the way in and decode on the way out. That way php or perl would be irrelevant. Guess not :\

tks for your help mitch

Well, as someone else already said, addslashes () is the tool of choice for the way in, and for he way out you don't need to do anything.

you dont need to have a list of field names if you insert the exact amount of fields that exist in the table...

if you have fields Name and Email, you can do: INSERT INTO mytable VALUES ('myname','myemail.com') without a problem. however, if you have fields Name, Email and Password the previous code will break, since MySQL would complain that you're inserting too few (or too many) pieces of data into the table, and it cant decide which data goes where

Hi,

I working on Redhat Linux 6.1 and I've installed MySQL-3.23.33-1.i386.rpm and MySQL-client-3.23.33-1.i386.rpm. MySql is working fine. I've even created a database also using MySqlAdmin. Regarding Php I've installed php-3.0.18-1.6.x.i386.rpm and as for Apache : apache-1.3.14-2.6.2.i386.rpm. I've even installed php-mysql-3.0.16-1.i386.rpm and mod-php3-3.0.12-2.i386.rpm.

My problem is I can't connect PHP to Mysql Db using the mysyql_connect("localhost","root","mypassword") command.

Please help me asap. Regards, George

mypassword is the same password you used for mysqladmin, and the command line interpreter for the root user, right?

Try this command and see what it returns. If the error message doesn't give you a good idea what is wrong, please post again, including the error message you receive.

mysql_connect( "localhost", "root", "mypassword" ) or die( "Unable to connect<BR>" . mysql_error());

I suggest you always use this code, along with:

mysql_select_db( "database" ) or die( "Unable to select<BR>" . mysql_error());

in every program you write. It is almost impossible to troubleshoot problems if you don't know what went wrong.

A simple solution for a site with a small number of pages would be to create an array like the following:

$location['/index.php'] = "Home"; $location['/services.php'] = "Services"; $location['/products.php'] = "Products";

Then use $SCRIPT_URL or a similar environment variable to display the proper label in the "location bar".

<?php echo $location[$SCRIPT_URL]; ?>

If you have a large number of pages (especially dynamically generated "virtual" pages) or sublevels to your site you'll probably want to use a more advanced solution.

attached mail follows:

You need to have an array or db with file and description

in ca you use array :

$location = Array( '/index.php' => 'HOME', '/prod_info.php' => 'Product Information', ..etc,,,,

);

and then

if(isset($location[$PHP_SELF])) echo $location[$PHP_SELF];

and so on ...

note: this is just a quick and dirty idea on how to do that, with a little bit of logic you can write a very sweet function with does what you need.

I don't agree with you in here,

you usually know what kind of variable you're checking, so strlen() will work just as well as

$var ? 'OK' : 'Empty'

will work or the isset() - common, it was made for checking the variables - use it.

strlen() is in fact an overhead, why would you allow your design to be some sort of untraditional? I don't think there's any necessity for it

a "good design" often would be something like this:

$var = 'whatever';

if($var) ...do this else ERROR('no var') // some your func to output the error mess or to continue with debugging

in most cases it will work better and simpler for you without spending these bazillions of important for every developer seconds.

I stand firm on strlen() for the following reasons ...

if(!$var) will sometimes act strangely (has for me in the past) when variables are set to something other than what you are expecting.

if(isset($var)) will return true if your text field is declared but not filled in.

if(empty($var)) will return true if $var is set to 0 (for obvious reason) so is only good for certain instances.

strlen() on the other hand converts the variable to a string and returns a count of characters. It's never failed or acted funky. For this reason I use it religiously.

Others might say "well it's extra overhead" to which I reply "I'll take an extra bazillionth of a second to know for sure I have what I need"

You are COMPLETELY wrong here. isset() is designed to check if a variable is SET - NOT if it has something in it. empty() is designed for strings NOT for ints - so if it's set to 0 it will fail. Finally in PHP 4 + you have problems when you do checks and variables aren't set.

I do this, like I said before, because the extra 1 billionth of a second is worth the overhead. I've programmed for sites ranging from a few hundered hits a day to a few million hits a day and this works ALL the time.

have I said it won't work, Joe?

I said that using strlen() might not be necessary. (re-read my post) On my own opinion the same things could be done without using the string functions. Am I wrong in something there? then thanks for correcting me - will know it for the feature.

You're wrong in saying that you "usually know what the variable will be" - you never know what it's going to be. You aren't entering it.... you need to remember that mostly idiots are inputting the data :O)

Whatever they input is not the objects, right?

then (I've just double-checked it, to be sure I am not saying some 'BULL')

$var = 0;

if($var) echo '<P>var matched';

if(isset($var)) echo '<P>var is set';

when the $var is 0 the second condition will return true, the first will be false instead... Obviously if they enter anything else then 0 and NULL (I mean nothing) it will return true in both cases, if($var.., if(isset($var... if(strle($var ...

What's wrong with isset() in here? I am on PHP4.0.4!

explain me again, why on user input strlen() would do better then isset() ?

the SOLUTION:

strlen() is the length of string, right? Then instead of doing

1. comparison 2. function execution

(I am talking here about your 1/bazillions of a second)

a perfect solution would be :

if($var!='')

and, this is only

1. comparison

am I right?

Now, no matter how much you care of thinking that the variable you need to match positive is a string longer then 0 characters

if($var!='')

will always do the same of strlen() but with less overhead and will add that 1/bazillion of a second to execution of your application...

I am so 'HOT' on this issue because it looks to me more silly then needed an extra string function during execution of a conditional.

nice day, Joe!

For the last time - put an input box on a page and submit with NOTHING in the box. Now I want SOMETHING in that box (like a name) - isset() will return true even though it's empty.

Hi (Soma Interesting?)

I am also a developer here in Tokyo and have done few I-Mode websites using PHP and mySQL. (I've used PostgreSQL with Japanese, but not for I-Mode) ( see www.japaninc.com/i )

There's no particular problems of storing the 2-bit data in your databases, the only thing is that to do sorting you have to compile the databases with the language needed ( regardless of which database you use - see their docs they all support that).

With PHP there's a little problem using string functions. strlen(), for instance will return you the number of bytes. In Latin characters ASCII 1-255 a character is a byte, but that doesn't apply to Japanese which use double bits (some characters are even three bits), so a strlen() will not return you the number of Hiragana & Kanji in string - it will return you the number of bits these Kanji were composed from - VERY, VERY UGLY....

You need to use PHP3 Japanese interpretation to do that kind of tasks.

In our company we use a different server for Japanese characters running PHP3 JIS, and the pages are being included form there.

IE: www.fusion-2000.net runs both PHP4 and PHP3 JIS with PostgreSQL at the back end.

While www.japaninc.com/i goes on PHP4.0.1pl2 and mySQL, (check out that game)

So, no worries, it is all possible to do, except there's a pain with choosing PHP version for the server.

Sincerely,

Maxim Maletsky Founder, Chief Developer

Hello everyone,

I'm currently working a project that is intended to handle Japanese character sets - and now I'm told ideally iMode too. :) The iMode isn't such an issue at the moment - but the article below has spooked me a little. At an early point in the project we tested if putting some input into a web form, which ultimately was handled by php then stored in postgres would return fully intact - and it did. This left me comfortable that PHP and Postgres don't seem to care what language they're storing in fields or variables. I'm 'guessing' that this is because the data, whether its English or Japanese is being stored in binary (or something else?). Of course I wouldn't be able to sort the data or do anything else that would require PHP/Postgres to be able to interpret the data. However if I compile Postgres with locals support for the character set/language in question - then postgres will be able to sort Japanese. Is this right?

Have I got this all right so far? I have attempted to do my research on this - but finding a real beginners guide to international web development has been a trick. And the best sources I have found on this topic generally are specific to Oracle. Any links would be appreciated.

Ok the next part of this message is an article I thought would be generally interesting so I'm not hesitating to post it entirely. It was forwarded to me so I'm not sure of the source.

For the postgres folks, these developers went with MySQL - I've chosen Postgres. Is there anything MySQL does that Postgres doesn't in terms of language support that I should be aware of?

Hello,

I am working on a PHP script for an e-commerce site that mails out calling card pin numbers after somebody purchases them online. Turing testing I not noticed that aol users were not receiving the messages. AOL seems to be filtering them out without sending a bounce or anything. We tried it with multiple aol users, and nothing I tried when using the mail function got through, but messages sent from the server with pine and the php mail package SquirrelMail do get through. The messages are received on every other mail system I have tried.

I know this is more of a mail question, but I was hoping somebody here and encountered this before and knew of a workaround. I noticed that SquirrelMail doesn't use the mail function, they chose to write their own SMPT package. I wonder why?

Anyway, my test scripts look like this: <?php

mail("steveexit1mile.com", "Test 1", "This is a test", "From: SteveExit1Mile.com\nReply-To: SteveExit1Mile.com\nX-Mailer: My test mail program\nX-Sender: SteveExit1Mile.com\nContent-Type: text/plain; charset=\"us-ascii\"");

echo "Mail sent!"; ?>

I tried playing around with different headers and nothing made any difference. I sent them to myself and they sure look like valid email messages to me. Does anybody else have this problem? What did you do about it?

Thanks,

Steve

<rant>

I have noticed a lot of people do not put quotes on their array indexes (e.g. VBulletin is a prime offender) - imho this is a really bad practice because your code becomes ambiguous.

Example:

<?php define("foo", "donkey");

$test = array("foo"=>"orange", "bar"=>"purple");

echo $test[foo]; ?>

Now, I think that should print nothing (or an error), because there is no index matching "donkey" (the value of the constant "foo"). But for some reason PHP looks for an array index matching the string "foo" as well, encouraging this kind of sloppy programming.

I'm using a remote host, and when I call mail() with all the var's pulling values from form fields, it still shows as nobody in from header. Is this a server situation? Theyre using php4 support and they claim its that I'm not using appropriate variables in the function.

Read the http://php.net/FAQ about the NULL character problem.

I'm betting you have some funky character that confuses that browser in the output that the other browsers just ignore.

You can also use an RC4Encryption / Decryption class made in PHP.

Hi Dhaval, You said in your previous e-mail 'C:\'. Are you using a NT based server or Unix based? If your server is a unix based one, consider trying this command: chmod 777 /path/to/directory Warning, this is a bit dangerous and might be vulnerable, are you running your webserver with nobody? Anyone else has access to write cgi scripts on your servers? If everything's set up carefully, you can chown your directory to nobody. It will work with the current permission. Ahmad Anvari

Hi, I'd like to do: $function = "build_result()"; $result = $$function; but it doesn't seem to work. The reason why I think I need it is that I have a generic function, but within it I have to call another function depending on who called it. I could build a switch within the generic function deciding which function to call, but tht seems less elegant, as I'd have to adjust the generic function every time a new function calls it. The build_result() function only gets called in certain cases by the generic function (if it's not cached), so I can't just put it outside fo the generic function. Any hints? Thanks!

Hi Kaab, There must be another problem, it should work. Maybe it helps if you send your code here. To see how a simple script works, try this tiny script named test.php:

<form action=test.php> <input type=submit name=more> </form> <?php if ($more) {print "<p>Submit is pressed</p>"; }; ?>

If you first load the php page, you don't see anything rather than a submit button. If you press submit, you will see a message.

The website I am working on has several forms, a search, and a login that can take close to a minute depending on much traffic it is recieving.

Here?! Sunny today! ;-) I highly suggest you use client side scripting in this case. onLoad Event handler. A load event occurs when Navigator finishes loading a window or all frames within a <FRAMESET> tag. The onLoad event handler executes JavaScript code when a load event occurs.

Here's a sample code for your result page:

<body onload=document.loadingimage.src='blank.gif'> ...... Some Coding Here ....... <p align=center><img src=loading.gif name=loadingimage></p> ...... The rest of coding...... </body>

That's the snippiest piece of code. [I didn't test it, however, I'm sure that it work out] Create a loading.gif animation gif which shows a [Loading...] animation.
