$PHP_SELF on Windows

lucianoes

I am writing a script with a lot of links that require $PHP_SELF, but $PHP_SELF is not available on Windows. How do you deal with that?

$PHP_SELF should be available on windows...maybe you don't have register globals turned on. try sticking

global $PHP_SELF;

in your scripts and seeing if it clears up..

Actually $PHP_SELF won't be available if register globals is turned off, you can access the same result via $_SERVER['SCRIPT_NAME'].. or in older versions of PHP ( < 4.1.x) $HTTP_SERVER_VARS['SCRIPT_NAME']

In that case I should get an error saying the variable doesn't exist. What happens instead is nothing is printed. Blank, zilch, nada.

Here is what the manual has to say:

"$PHP_SELF: The filename of the currently executing script, relative to the document root. If PHP is running as a command-line processor, this variable is not available."

I have PHP running as a command-line processor, not as a server module. So I guess that means it is just not available in my Windows setup.

ahh, very true if using in CGI.

try the isapi version if its a critical part of your script 🙂

just tried it on my install.

WinXP
Apache 1.3.22
PHP 4.1.1 using php4apache.dll and php4ts.dll
MySQL 3.23.47

ran %webroot%/authmain.php

returned

/authmain.php
as expected.

Do you need this as part of you scripts?...

The reason is that when you call php.exe as a CGI executable, it exists in a temp space to do work and then disappears...

using the isapi versions you have php "running" as a library...and hence can use it to call "itself" as far as which script it is running

isa what????
oh, well, back to the manual...

Here's the news: I remembered I had used $PHP_SELF in another script weeks ago. I found the script and it works! Now I just gotta find out why it works in one and not in the other.

Thanks for all the help so far.

From my book:

<quote>Apache for WIndows version 1.3 series is implemented in synchronous calls. This poses an enormous problem for CGI authors, who won't see unbuffered results sent immediately to the browser. This is not the behavior described for CGI in Apache, but it a side effect of the Windows port. Apache 2.0 is making progress to implement the expected asynchronous behavior, and we hope to discover that the NT/2000 implementation enables CGI to behave as documented</quote>

"From my book" like in "from this book on my shelf next to my head" or "From my book" like in "from the book that I wrote, has been published and is available at the best establishments in the literature retail business near you"?

Please accept my apologies, I forgot to say that I am using Xitami. There is something in Apache that I hate: every time I run a script (or access it with the browser), two DOS windows pop-up in front of everything, very annoying.

to lose the dos windows , at a command prompt cd to the apache directory

cd c:\apache\apache.exe -i

this will install apache as a service (on 98 & NT etc) then apache will start up when windows does - no more boxes - better still no more xitami 😉

Thanks, but I run Win 95.
Seriously.
