When building querystrings, you often need to pass original arguments into the new querystring. An
easy way to combine a bunch of default values, plus some overwrites into a new array, is using the
Array operator +. This works great with http_build_query:
<?php
# Suppose $_GET is set like this.
# or put some default values in here.
$_GET = Array( 'page' => 'item', 'id' => 14, 'action'
=> 'view' );
$edit_url = http_build_query( Array( 'action' => 'edit' ) + $_GET );
echo "<a href=\"$edit_url\">Edit</a>";
/* Prints
<a href="action=edit&page=item&id=14">Edit</a>
*/
?>
