Just upgraded to PHP 5

Notice: Undefined index: REFERER

[gms3651]

Here is my php code

<?php
$testvar = $_SERVER['REFERER'];
echo $testvar;
?>

For some reason this produces the error 'Notice: Undefined index: REFERER in /web/apple/adduser.php on line 2'.

Any help would be appreciated.

Thank You

echo $_SERVER['HTTP_REFERER'];

Predefined Variables [us2.php.net].

Also, if you just upgraded, did you upgrade to PHP 5.2.0 [webmasterworld.com]? ;)

Thanks...that worked. Is that a change with PHP 5 to use $_SERVER['HTTP_REFERER']; instead of $_SERVER['REFERER'];?

Thanks

No; it's been that way as far as I can remember.
