Subject: RE: [PHP-DEV] Namespace
From: scott.mcnaught@synergy8.com

Quick question... If I wanted to override or extend php's functions... Could
this work?

Say I want to change the implementation of var_dump() to make it more html
friendly... 

function var_dump($mixedVariable)
{
	echo('<pre>');
	::var_dump($mixedVariable);
	echo('</pre>');
}

Subject: Re: [PHP-DEV] Namespace

Once you say "namespace xyz ;" everything in the file is now relative to
namespace xyz. To refer to the global namespace, you use the following

<?php

namespace xyz ;

function substr() {
	return true ;
}

substr(); // calls substr in current namespace
::substr(); // calls substr in global namespace

?>
