1.2.1158. Static Variable In Namespace¶

Static variables may be declared outside a function scope, but it has no usage. Static variables are persistent between function calls, and there is not such thing as namespace call (including an ‘include’ call).

<?php

namespace A {
     // Static has no value here.
     static $a = 1;

     function foo() {
             // One useful static variable
             static $static = 2;
     }
}

?>
