Is it possible to create a global namespace alias?

["Matt Palermo" <palermomatt@xxxxxxxxx>]

ïIs it possible to create a global namespace alias in PHP or does the alias have to be defined in EVERY file that I use?  Here is an example:

file:  main.php
<?php
use \this\is\my\custom\namespace\Item as nsItem;
?>


file:  index.php
<?php
require_once âmain.phpâ;

// Attempt to use namespace alias defined in main.php file
nsItem::test();
?>


The above code doesnât work for me.  The namespace alias defined in the main.php file isnât accessible in the index.php file.  Is there a way to make the ânsItemâ alias a âglobalâ one, so that I donât have to define it in EVERY file that I want to use?
