URL variables do not come across with PHP

[ojav]

I just installed PHP 5.0.18 on a SuSE Linux server. Everything else seems to work allright, but the variables which are sent with URL are ignored.

On a page with URL
mypage.php?variable=3


This code should print ´3´ , but it does not.
echo "$variable";


Did I overlook something when I installed PHP?

PHP does not automatically create the variables for you to use. Instead, they are passed in a special array depending on how they were passed: $_POST for POST variables, and $_GET for GET variables. If you don't care, then you can use $_REQUEST.

So we can one of the following:

echo $_GET['variable'];
echo $_REQUEST['variable'];

Hope that helps.

$_GET[] and $_REQUEST[] do work, but why does this code give different resul on my recently installed server than on my old server

<?php
echo "<a href=mypage.php?var=2>click</a>";
echo "<br>first ";
echo $var;
echo "<br>second ";
echo $_REQUEST['var'];
?>

On my new server clicking on the link produces page like this

click
first
second 2

whereas the old server gives a page like this

click
first 2
second 2

Otherwise I would not mind, but there will be one helluva lot of work in adding "$_REQUEST" to my formerly written codes.

This is a change made in PHP 4.2.0. It is well explained at:
PHP: Using Register Globals - Manual

I get it. Thanks
