Pseudo-Named Argument in PHP (this is a bad idea because you loose type hinting)

argument.php

<?php

class Foo {
    
    public static function getBar($args)
    {
        $args += [
            'foo'   => null,
            'bar'   => false,
            'baz'   => null
        ];
        
        extract($args);
        
        //...
    }
}

Foo::getBar(['foo' => 'foo']);
