Weird: $PHP_SELF not working inside function

chakotha

Hi

I have a function in which I wish to compare a filename against $PHP_SELF but I can't seem to reference $PHP_SELF from inside the function

eg. A trimmed down example

[PHP] <?
function show_this_page() {
echo("PHP_SELF from inside function =".$PHP_SELF."<br><br>");
}
show_this_page();

echo("PHP_SELF from outside function =".$PHP_SELF."<br><br>");

?> [/PHP]

is returning

PHP_SELF from inside function =

PHP_SELF from outside function =/test.php

WTF? Many Thanks

Perhaps you need to pass $PHP_SELF in as an argument?

i take it your register_globals is turned off..

use the superglobals, $_SERVER[PHP_SELF]

[PHP]
<?
function show_this_page() {
echo("PHP_SELF from inside function =".$_SERVER[PHP_SELF]."<br><br>");
}
show_this_page();

echo("PHP_SELF from outside function =".$PHP_SELF."<br><br>");
?>
[/PHP]

Thanks $_SERVER["PHP_SELF"] did it - thought I'd cured myself of those habits!

<?
function show_this_page() {
global $PHP_SELF;
echo("PHP_SELF from inside function =".$PHP_SELF."<br><br>");
}
show_this_page();

echo("PHP_SELF from outside function =".$PHP_SELF."<br><br>");

?>


No global var's are accessable within functions in PHP, so you must declare them as such.

Also if you wanted to create a new global variable within the function you would use
global $MY_VAR = "bleh";

using it with any assignment basically just imports it into the function though.
