1.2.177. Collect Local Variable Counts

This analysis collects the number of local variables used in a method or a function.

The count applies to functions, methods, closures and arrow functions.

Arguments and global variables are not counted. Static variables are.

<?php

function foo($arg) {
    global $w;

    // This is a local variable
    $x = rand(1, 2);

    return $x + $arg + $w;
}

?>
