help with manipulating $_SERVER statement

When I use the code

<?php
$path = $_SERVER['REQUEST_URI']; 
echo $path;
?>

PHP:

I get an echo similar to "/example/index.php?a=test". I was wondering it it was possible only to echo out what follows the "=" sign? Any ideas?

 

ya use preg_split, through this you can do that, but i dont know exactly.........!

it's my idea..! but it is possible with that sure.

 

what do you mean?
get the 'a' value?

 

You can access the full query string only (the bit after ?) by using $_SERVER['QUERY_STRING']

If you know which variable you are trying to get the value of, you can access it, as per your example, as $_GET['a']
