1.2.662. Make Magic Concrete

Speed up execution by replacing magic calls by concrete properties.

Magic properties are managed dynamically, with __get() and __set(). They replace property access by a methodcall, and they are much slower than the first.

When a property name is getting used more often, it is worth creating a concrete property, and skip the method call. The threshold for magicMemberUsage is 1, by default.

<?php

class x {
    private $values = array('a' => 1,
                            'b' => 2);

    function __get($name) {
        return $this->values[$name] ?? '';
    }
}

$x = new x();
// Access to 'a' is repeated in the code, at least 'magicMemberUsage' time (cf configuration below)
echo $x->a;

?>

Name	Default	Type	Description
magicMemberUsage	1	integer	Minimal number of magic member usage across the code, to trigger a concrete property.
