$PHP_SELF A Strange Behavior!?

saidbakr

As we know $PHP_SELF is a PHP predifined variable. It handles the current file name and extension.
I have a file contains commonly used functions. it's named func.php. Inside some of these functions, I use $PHP_SELF.
I perform include for this file in another file called index.php.
The strange behavior is, in some code area $PHP_SELF does not return any value, in other word,
it does not return index.php. However, in other areas it works properly!
So What's the cause of this problem?
Is it bug in my PHP?
I use PHP Ver 4.2.3 on Apache, and windows ME. All this from phpdev423 package.
😕

Are you properly declaring global variables that you attempt to use inside functions?

If by "other areas" you mean other sites, the convention these days is to use $_SERVER['PHP_SELF'] instead, because since PHP4.1 $PHP_SELF is no longer defined by default, and unless you deliberately state otherwise, is not defined inside functions anyway.

If by "other areas" you mean other pages on the same site, and that the same functions are working on those other pages, then seeing some code would be helpful: what is different about how index.php uses those functions and how the other pages use them?

What I meant by other area, is other line of code in the same page,
Suppose,
the func.php contains fox_it() and do_it() functions
each one uses $PHP_SELF in it.
in index.php

fox_it();
do_it();

The problem is like that fox_it() print out the page name index.php
while do_it does not.
at the same time.

Yes some of these functions contains global variables.
Is this the cause?!:eek:
