PHP script does not understand the variables from the URL?

PHP script does not understand the variables from the URL?

Hello, can you please help me with the following very strange problem? It is the first time I ever see a problem like this: the PHP script does not understand the variables passed to it by URL. To explain the point I made a very simple script test.php consisting of the text:

<?php
echo $signal;
?>

So if we call this script by browser as:
www.MyServer.com/test.php?signal=777
then it need output the text “777”. However, it does not do that.

To test if PHP in general works on this server I made another simple script like:

<?php
$signal = 888;
echo $signal;
?>

Which DID output the text “888”

Can somebody have an idea what is the problem?

Thank you!

hi,

That will only work if register_globals is turned on. If it isn't, which has been the default for some years now (due to security reasons), you need to grab the variable from the $_GET array:

PHP Code:

---

<?php
echo $_GET['signal'];
?>

Thank you very much! It worked.
