Object creation in PHP, which approach is faster? new, clone or unserialize???

benchmark.php

<?php

function leSerialize()
{
    for ($i = 0; $i < 1000; $i++)
        unserialize('O:8:"stdClass":0:{}');
}

function leNew()
{
    for ($i = 0; $i < 1000; $i++)
        new stdClass();
}

function leClone()
{
    $a = new stdClass();
   
    for ($i = 0; $i < 1000; $i++)
        clone $a;
}

leSerialize();

leNew();

leClone();

function leClone()
{
    $a = new stdClass();
    
    for ($i = 0; $i < 1000; $i++)
        clone $a;
}

function leJson()
{
    $json = '{}';
    
    for ($i = 0; $i < 1000; $i++)
        json_decode($json);
}

function leReflection()
{
    $class = new ReflectionClass('stdClass');
    
    for ($i = 0; $i < 1000; $i++)
        $class->newInstance();
}

leSerialize();

leNew();

leClone();

leJson();

leReflection();

i'm burn.
Cool, our job discuss... maybe we can use reflection, json_decode and others too

You should run the tests in separate processes.
