1.2.247. Could Be A Static Variable¶

This global is only used in one function or method. It may be transformed into a ‘static’ variable, instead of global. This allows you to keep the value between call to the function, but will not be accessible outside this function.

<?php
function foo( ) {
    static $variableIsReservedForX; // only accessible within foo( ), even between calls.
    global $variableIsGlobal;       //      accessible everywhere in the application
}
?>
