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>');
}

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
?>
