But if you don't want to change all of your code, and open a security
hole, you can turn 'register_globals' on in the php.ini

Thanks John for your quick answer.
What I'm looking for is for a miraculous way to convert or adapt my existing
code.
I already detected where are each one of my lost variables. I just want to
know if the only way I have is to manually replace every old variable by the
new one.
Hope not.

You can turn 'register_globals' on in the php.ini, but it would be
better to leave it off, and change your code.

Please reply to the list, and not just me. That way, when someone else
who has this problem will be able to search it in the archives.
Okay, this is the error reporting level. In the php.ini you can set
'error_reporting' to E_ALL & ~E_NOTICE to get rid of the warnings, or
you can turn 'display_errors' to Off (restart of web server needed for
the changes to take effect). Of course, it's still better to write your
code to where you don't get these warnnings.

Hi,
I've read and re-read array_multisort(), but still can't get a grip on
how to sort my array:
Array
(
[0] => Array
(
[path_id] => 3
[year] => 2004
[month] => 02
[day] => 05
[hits] => 3
[path] => home
)
[1] => Array
(
[path_id] => 2
[year] => 2004
[month] => 02
[day] => 05
[hits] => 1
[path] => plan
)
[2] => Array
(
[path_id] => 7
[year] => 2004
[month] => 02
[day] => 05
[hits] => 1
[path] => specials
)
)
In this case, I'd like to sort the entire array on [path]. Can anyone
provide some tips or an example to start from?

... etc.
I'm pretty sure this is one where multisort() is not the best approach, and usort() (or one of its friends) is where to look.

Assuming your array is called $array1:
$paths = array();
foreach ($array1 as $data_ptr => $data)
{
if (!in_array($data['path'],$paths) $paths[] = $data;
}
sort($paths)
foreach($paths as $path_to_check)
{
foreach($array1 as $data_ptr => $data)
{
if ($data['path'] == $path_to_check)
{
/** Do your stuff here **/
}
}
}
It's a little cumbersome and probably has way too many loops, but
processor time is cheap and memory is even cheaper. I've found PHP's
array parsing to be fairly quick.
Alternatively, use the path as the index for your array; i.e:
$array1 = array("path" => array("path_id" => 3,
"year" => 2004,
"month" => "02",
"day" => "05",
"hits" => 3);
When you're parsing your log (which is what I'm assuming you're doing),
you would populate $array1 as follows:
$array1 = array();
while (parsing())
{
$array1[$path]['path_id'] = $path_id;
$array1[$path]['year'] = $year;
/** etc... **/
}
$paths = array_keys($array1);
sort($paths);
foreach($paths as $path_to_check)
{
/** Do stuff with $array1[$path_to_check] **/
}

Hi all,
is there function which scans a particual directory recurisly and stores the content in array or other way? Listing of files should be in alphabetical way and directories should come on top.
Thanks
Binay
attached mail follows:
I don't know if there's a built-in function, but I had written this
function, which does what you're trying to do, I think. You can modify
it to store the values in an array, if you like. I just have it echoing
the files (with their full paths).
Here's the function:
function readDir ($dirPath)
{
if (is_dir($dirPath)) {
$fstream = opendir($dirPath);
while ($fentry = readdir($fstream)) {
if (is_dir("$dirPath/$fentry") && ($fentry != ".") &&
($fentry != "..")) {
echo "$dirPath/$fentry";
readDir("$dirPath/$fentry");
} elseif (is_file("$dirPath/$fentry")) {
echo "$dirPath/$fentry";
}
}
closedir($fstream);
return true;
} else {
return false;
}
}
Hope this helps!

This is probably a MySQL question, and maybe an easy question, but I'm here to learn <|:)
When I order by number, it echoes 1,2,3,4,5,6,7,8,9,10 and hten jumps to 100...199 before it comes back to 11-19. Any way of ordering that differently?

I assume "number" is a column name in your table. If so, I'm also

but it makes sense in an alphabetical way.
If it is character data, then it should order like this:
1
10
11
12

2
3
4
...
To correct it, put a zero at the beginning of your single digits:
01
02
03

10
11
12
That will order it correctly. Otherwise, change the number column to
type int, and it should work just fine.

Hi list!
Yesterday I've installed PHP 4.3.4 and Apache 1.3.29
on my Linux Mandrake 9.1 machine with a standard
procedure:
1. cd apache_1.3.29
2. ./configure
3. cd ../php-4.3.4
4. ./configure --with-apache=../apache_1.3.29
--enable-track-vars && make && make install
5. cd ../apache_1.3.29
6. ./configure
--activate-module=src/modules/php4/libphp4.a
7. make && make install
8. cd ../php-4.3.4
9. cp php.ini-dist /usr/local/lib/php.ini
10. In httpd.conf file: "AddType
application/x-httpd-php .php"
I've encounterd a problem with this snippet of code,
where I fill a form and I pass the data to a php page
that should visualize it. Here is the code:
//Login.php
<html>
<head>
<title>TEST</title>
</head>
<form method="post" action="second.php">
<br><br><br>
NAME : <input type="text" name="ident">
<br>
PASSWORD :<input type="password" name="psw">
<br>
<input type="submit" name="Submit" value="Submit">
</form>
</body>
</html>
//second.php
<?php
echo "NAME = $ident <br> PASSWORD = $psw";
?>
When I execute this code in my web page
http://members.lycos.co.uk/ippo80/Login.php, or in
another Apache server with PHP-4.2.3 not installed by
me, the name and password are correctly visualized
once I click the submit button:
NAME = myname
PASSWORD = mypassword
, but on my recently installed server I obtain
NAME =
PASSWORD =
indicating that variable values are not transmitted.
Have you any idea about the reason of this behaviour?
Thank you very much for the attention,
Giuliano

Thank you very much Jason: the problem was originated
by "register_globals = Off". I turned it into On and
now it works. However in the future I'll use
$_POST("...") to pass variables.
Thank you very much again,

No, that's 50 *characters* -- he wanted 50 *words*. A quick and
reasonably accurate[1] solution would be this:
Daniel,
There's a few things you need to look out for. If there's tags (like
<b> or <a>) in the text, and you chop the text inside an open tag, it
will break your pages, cause them to be invalid, and make them look
really strange. So the first thing you want to do with the text is
strip the tags.
I'd say the next issue is to only append the 'read more' link if the
article is great than the teaser limit -- that way 'read more' only
appears when it's correct.
You should wrap it in a function so that you only ever write this code
once too.
Here's a stripped-down version of what I use:
<?
function chopper($input,$wordcount,$append='')
{
$input = trim(strip_tags($input));
$words = explode(' ',$input);
$output = '';
for($i=0; $i<=$wordcount; $i++)
{
$output .= $words[$i].' ';
}
trim($output);
if( ($i == $wordcount) && (!empty($append)) )
{
$output .= $append;
}
return $output;
}

[1]: It's reasonably accurate in that it breaks words on spaces, then
glues them back together up to the limit. However, there are some
words which you may consider to have a space in them, but still be
considered one word. A perfect example would be "Leonardo da Vinci"
which the above function will see as 3 words, and you may consider it
to be 2.

Is there anything similar to 'global.asa' which is used in ASP applications

PHP Manual:
If register_globals is enabled, then each global variable can be registered
as session variable. Upon a restart of a session, these variables will be
restored to corresponding global variables. Since PHP must know which global
variables are registered as session variables, users need to register
variables with session_register() function. You can avoid this by simply
setting entries in $_SESSION.
just set the superglobal to the desired value. to remove when you're through
you can use session_unregister('foo') or unset($_SESSION['foo']). do not
unset $_SESSION itself!!!
$_SESSION['foo'] = "bar";

Hi all,
I m using Turck MMcache for php source encoding. Now the server where i will deploy those file need to have turck loader installed on it. And the procedure given in the site requires compiling the source and then including the TurckLoader.so extension in php.ini file .
Now is it possible not to compile the turck source on client's server and simply include the extension TurckLoader.so(which i'll provide them) in php.ini i.e bypassing the compile face.
Please let me know .. as this is very urgent and client is not a techy person.
Thanks

It ought to be possible providing that you compile the extension on a server
that is similar to the client's. Similar, meaning the same versions of
support libraries, apache, php etc etc.

Hi Larry, many thanks for the recommendation. That will be just perfect.
I've informed my manager about it, and I imagine he'd be happy for the fact that we'll be saving quite a lot of money as well.
Also thanks for the other recommendations - but unfortunately, we need Solaris compatibility now.
Thanks again!

We have a server that need to be as secure as possible, since it's containing some very sensitive personal data.
We have hardened the box, setup very restrictive firewall rules to it, keeping up to date with the security patches, and so on. But just in case that a cracker still manage to break in, we'd like to make it a real hassle for him/her to read the content in the server.
So I was tasked to create a PHP application which will enable the following scenario:
# Webteam will still create contents in Dreamweaver
# Once done, upload the contents to the server using the upload script.
# The upload script will put and encrypt the contents in the server using the strongest encryption available
# Users will access the content using the second script, which will decrypt the content on-the-fly; so the URL will be something like this:
https://www.mydomain.com/view.php?file=/mydata/index.html
As you can see, the content will be secured, but the script is now becoming the weak point since it'll store the encryption key needed to decrypt the content.
So double-encoding it (using a PHP encoder) will make life finally very hard for said cracker.
by the way, if anyone's interested on such application, I'm planning to release it as an open-source application, so you'll be able to utilise it as well.
cheers, HS

I hope you don't mean that literally. If you're really being security conscious, the encryption keys should be in an include file that lives *outside* the Web document tree. If your include path is given relative to the including script, a hacker also has to know the local pathname to the script in order to deduce the location of the included file containing the keys.
On my site, the *only* PHP scripts visible to the Web server look like this:
<?php
ini_set('include_path', '../../relative/path/to/includes/');
require 'real_script.php';
?>
... and the only reason that the include_path is set there and not in php.ini or equivalent is that I'm not the admin of the server and don't have access to configuration files!
Cheers!
Mike

Of course we'll do it like that.
And anyway I was talking about if the cracker has actually gained (root) access to that server itself - which makes putting the keys outside the web directory irrelevant.

So there's a reasonably easy way to decrypt those encoded files then ? (despite those vendors' claim...)

OK, good -- I kind of assumed so, given your other precautions, but just
thought I'd clarify for any novices coming upon this thread in the
archives... ;)

hi at all,
i've a very strange problem but i don't know if this a real bug or only my
imcompetence?!
it is a problem with class variables set by __constructor() function in
PHP5...
look at this code:
<?
class MyClass extends DomNode { // remove "extends DomNode" and
everything is fine
private $__arr = Array();
public function __construct() {
//$this->__arr = Array(); // uncomment this line for testing
$this->__setVar("value set inside constructor");
}
public function __setVar($classname) {
print("\n\nexecuting __setVar()\n");
print("trying to push \"" . $classname . "\" into \$this->__arr
with array_push\n");
// array_push only works in several cases...
array_push($this->__arr, $classname);
// comment following line for testing
//$this->__arr[] = $classname;
/*
foreach($this->__arr as $parentClassname) {
print($parentClassname . "\n");
}
*/
}
}
print("<pre>");
$node = new MyClass();
print_r($node);
$node->__setVar("value set outside object method");
print_r($node);
print("</pre>");
?>
output:
*******************************************
executing __setVar()
trying to push "value set inside constructor" into $this->__arr with
array_push
MyClass Object
(
[__arr:private] => Array
(
)
)
executing __setVar()
trying to push "value set outside object method" into $this->__arr with
array_push
MyClass Object
(
[__arr:private] => Array
(
[0] => value set outside object method
)
)
*******************************************
ok, in my opinion the Array $this->_arr should have a value "value set
inside constructor" after creating the object set by array_push (see output
line 2)!
But there are several cases in which this bug does not appear:
- remove "extends DomNode" from code and it works fine
...but what does DomNode with my __construct() function?!
- uncomment line 6 and it will work
...don't ask me why it works now?!
- uncomment line 19 and it will work
...seens that array_push does not work correctly.
by the way i'm using PHP5 cvs-version from 2004-05-02 10:30...
maybe you could help me out of this dilemma..
another question for the php experts: is this information enough for sending
a bug to php.bugs?
thanks for your attention.

I have been messing around now for some hours and Im going mad!
Im pulling some heavy data from mySQL with count and grouping,
after this I have to calculate som values and then sort the outcome.
Therefore Im not able to let mySQL do the accuall sort.
So i stuff it into an array, and I need to sort the array and thats where
the problem occures.
1. I declare an array :
$stats_unsorted = array();
for loop start ...
1. fetch mySQL data
2. calculate values
array_push($stats_unsorted,$sum,$user);
// Eks. array_push($stats_unsorted,10,Ola);
// Eks. array_push($stats_unsorted,-5,Kaare);
// Eks. array_push($stats_unsorted,203,Nils);
// Eks. array_push($stats_unsorted,-20,Lars);
for loop end ...
We now have, e.g. this :
Array
(
[0] => Array
(
[0] => 10
[1] => Ola
)
[1] => Array
(
[0] => -5
[1] => Kaare
)
[2] => Array
(
[0] => 203
[1] => Nils
)
[3] => Array
(
[0] => -20
[1] => Tone
)
)
- - - - - - - - - - - - - - - - - - - -
Then comes the sorting part, I want to sort by this :
$stats_unsorted[x][0]
meaning the numbers, ofcourse I would surely like to know
how to sort by the names aswell, $stats_unsorted[x][1],
but I would think that is easy if I could figure out the
main command to sort this in the first place.
Ive tried several times with array_multisort(); but I cant get this
to work, :(
Help would be appretiated!
$stats_SORTED = ???;
Thanks in advance!

OK, typically when finally biting the dust and asking for help
the answer comes falling down from above...
I figured out that a simple :
sort($stats_unsorted);
This would infact sort the first field of the subarrays.
This would mean by throwing the results back and forth
between several arrays I would in the end be able to sort
whatever I would need.
I could also insert back into the SQL and sort it by a select
statement, but I feel Arrays are there for a reason, and there
should not be any reason to bother the SQL for such a trivial
thing as sorting.
If any of you have another sollution I would sure love to know it,
since my array infact is multidimensional, and the sort() isnt,
though it for some reason solved the problem aslong as Im
sorting the first field.

You can use usort for multi dimension arrays:
<?php
function cmp($a, $b) {
if ($a[0] == $b[0]) {
return 0;
}
return ($a[0] < $b[0]) ? -1 : 1;
}
$a = array(
0 => Array(0 => 10,1 => 'Ola'),
1 => Array(0 => -5,1 => 'Kaare'),
2 => Array(0 => 203,1 => 'Nils'),
3 => Array(0 => -20,1 => 'Tone'));
usort($a, "cmp");
print_r($a);
?>

Hi,
I've been working with a PHP for a few years now. I've always thought
that on production servers, to have them working at peak efficiency, I
should have the Apache and PHP compiled as a static build. I recently
got into a debate with someone over whether this had any worthwhile
savings. Can anyone tell me which is the best solution, or point me in
the direction of a solution? I realise that it would vary from situation
to situation, so I'll tell you that my situation is high load servers
required to run as fast as possible. They get restarted once a day, and
(ideally) only get php+apache rebuilt when there's new versions out.
Thanks for any advice you can offer,
John
