PHP_SELF inside functions

grantp

I want to write a function that will return different results depending on which page it was called from.
I would like to have it detect it's context instead of passing it.

intead of:
function foo($curURL)
{
echo "$curURL";
}
then going
foo("$PHP_SELF");

I want to go:
function foo()
{
echo "$PHP_SELF";
}
so I can just
foo();

but when I do this I get an empty string not the current URL from whence the function was called.
For some reason I feel, as it's predefined I should be able to use it as a global.
Bad thinking?

I've PHP Version 4.0.4pl1 on a stock RH7.1 system.

Thanks everyone.

try putting:-

global $PHP_SELF;

in the top of your function.

Works for me!

Uh hemm - Yep, that was sooo the right answer.
Thanks so much, I don't think I would have got that for days.

foo()
{
global $PHP_SELF;
echo "[$PHP_SELF]";
}
foo();

now shows
[/bar/foo.php]

unlike

foo()
{
echo"[$php_SELF]";
}
foo();
which shows
[]

Ta.

Hi,

I am having trouble with the $PHP_SELF
variable. I am using IIS on win2K
I always get empty for PHP_SELF.

So if i dump the following in a file:

<?php
echo "X".$PHP_SELF."X";
?>

All I get out when I load the page
is:

using
<?php
global $PHP_INFO;
echo "X".$PHP_SELF."X";
?>
doesn't work either. Any one have any suggetions?

thanx
Greg
