Hi,

I just upgraded to 4.2.3 with apache 2.0.42 this evening and my scripts no longer function as before.

For example if I send a GET_Method URL to my server:
http://www.geomagnet.com/redirect.html?url=www.atomflash.com

the script:

<?

        header("Location:http://$url");
        exit;

?>

No longer functions unless I add this line before the header function.

$url=$_GET["url"];

Do I have to now define the variables (as in PERL)?
or is this a bug.

Thanks
Scott STolpmann

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Since PHP 4.2.0 register_globals are off by default, this is why $url is blank. If you turn them on in php.ini, you will be able to use $url.

In PHP 4.2.0, the 'register_globals' setting default changed to
'off'. See http://www.php.net/release_4_2_0.php for more info.
We are sorry about the inconvenience, but this change was a necessary
part of our efforts to make PHP scripting more secure and portable.
