1.2.1416. Variable Is A Local Constant

A variable that is written once, then never modified : it behaves like a constant. Some other rule may take advantage of this.

<?php

function foo() {
    $localConstant = 'Hello';
    echo $localConstant;

    $variable = 'Hello, ';
    $variable .= date('r');
    echo $variable;
}

?>
