[manashi_130582]

hi...
i want to know when we should use $_SERVER['QUERY_STRING']
and how it works..
the code is ..

<?php

$tmp = $_SERVER['QUERY_STRING'];
$tmp = explode("=",$tmp);
$id = $tmp[1];

if(!$id)
{
echo "<p>No id passed";
include("footer.html");
return;
}
?>

Usually, never. It can be used for special cases such as to get the path to the current directory from the browser's point of view. For the above, $_GET['id'] will work fine.

P.S. close that <p> tag!

From the query string? Wouldn't that particular case be covered by the REQUEST_URI property?

Not necessary, though it is something that I always do. The more important markup problem is the erroneous use of heading elements. Never use a heading element - of any level - just because you think it looks right. For a start, it may not in someone else's browser but, more importantly, nothing but headings should be marked-up by heading elements.

Yes, but the query string would work too.
