Getting a url string variable

[thepez]

Out of all the tutorials I've read on PHP, not one of them has showed me how to get a URL string variable! All I want to do is pass a variable in the url and retrieve it and see if it exists. Jeeeeeezzz !.. Help.. 🙂

Hi,

Here is a simple example:

page 1:

<?php
$variable1="42";

<a href=\"http://www.somepage.com/somefile.php?colID=$variable1\">click here</a>
?>

page 2:
ie when you click on the above link

if ($colID){
    /*the variable has arrived*/
    echo $colID;
}else{
    /*no variable*/
}

hope this helps

/s
