Someone asked this on the PHP list today, so here it is for everyone!

$_SERVER['PHP_SELF'] (or even just $PHP_SELF on most PHP installs) is great for getting the name of
the script/url currently being executed, or for pointing a script to itself, etc etc.

But sometimes you also need the querystring (everything after the '?') as well.

The one line version:
<?php
$foo
= $_SERVER['PHP_SELF']."?".$_SERVER['QUERY_STRING'];
?>


... this works fine, but if there's no query string, it will still have the '?', so the better
version:

<?php
if($_SERVER['QUERY_STRING']) {
   
$foo = $_SERVER['PHP_SELF']."?".$_SERVER['QUERY_STRING'];
} else {
   
$foo = $_SERVER['PHP_SELF'];
}
?>


In the case of a URL like http://www.preshrunk.com/history.php?page=browse&year=2002, $foo would
contain 'page=browse&year=2002'.

The above assumes PHP >= 4.1 (superglobal arrays used).

Consider the case of an included script 

If it needs to know it`s own location (and you don`t want to hardcode it) how does that script know it`s location?
