Global space

(PHP 5 >= 5.3.0, PHP 7)

Examples:

Using global space specification

Without any namespace definition, all class and function definitions are placed into the global space - as it was in PHP before namespaces were supported. Prefixing a name with \ will specify that the name is required from the global space even in the context of the namespace.

<?php
namespace A\B\C;
 
/* This function is A\B\C\fopen */
function fopen() { 
     /* ... */
     $f = \fopen(...); // call global fopen
     return $f;
} 
?>
