[RESOLVED] PHP_SELF and IIS ?

wscreate

HI,

I have this wierd situation I have never seen before... I have php 5.2.4 installed on a WinIIK3 Server with IIS6. I use $PHP_SELF in my forms to repost back to the same page.

Example
<form method='post' action='$PHP_SELF'>

However, the value of $PHP_SELF is not correct. It duplicates itself.

Example when viewing a page called "test.php"
<?
print "PHP_SELF = " . "$PHP_SELF";
?>

Will display this....

PHP_SELF = /test.php/test.php

What might be causing this to duplicate? I have double checked and I do not have $PHP_SELF listed twice in the print command.

Where do you define the variable $PHP_SELF? (The pre-defined variable is $_SERVER['PHP_SELF'].)

It shows up as a duplicate whether I use the pre-defined variable or state the variable as

$PHP_SELF = $_SERVER['PHP_SELF'];

It is the strangest thing. The attached .jpg file shows a screenshot of part of the phpinfo read-out that shows the duplicate for PHP_SELF

There's no way for us to know what's wrong without seeing the code. I would suggest you start by searching through the source and look at each line where you reference the variable in question in order to find out how it gets set or modified.

I uninstalled PHP 5.2.4 (cgi-binary on Windows) and resintalled it. Same problem. I then uninstalled the cgi-binary again and reinstalled it as an ISAPI module.

Installing PHP 5.2.4 as an ISAPI module fixed the problem. I have no idea why the issue was present in the cgi-binary installation and not the isapi module.

This is resolved for me, so I will mark it so.

BTW... what are you talking about? $PHP_SELF will always reflect the page you are using the variable on. Ergo, $PHP_SELF . It works by default with a php installation.

Example
You can put only a single print statement in a page called "test.php" and it will display the page name. You do not have to "set" anything.

<?
print "Page Name: $PHP_SELF";
?>

Would output Page Name: test.php

Just an FYI for anyone who may have become confused.

$PHP_SELF will only be set if register_globals is turned on. As I always have it turned off (since it is considered to be deprecated and can have adverse side-effects), for me it was an undefined variable until I decided to see what would happen if I turned register_globals on.

As to why you were getting doubled-up values for it in you initial configuration, I have no idea; but I do recommend turning off register_globals and using $_SERVER['PHP_SELF'] instead.
