同时对以下几种PHP的序列化方案进行了测试：
- serialize() and unserialize()
- json_encode() and json_decode()
- msgpack_serialize() and msgpack_unserialize()
- igbinary_serialize() and igbinary_unserialize()
测试环境：
- OS: Archlinux 32-bit
- CPU: CORE 2 DUO T9400, 2.53GHz
- Mem: DDR3, 3G
- Server: nginx v1.0.0
- PHP: php v5.3.6 + php-fpm
- Profiler: xhprof v0.9.2
测试代码块：
```php value = str_repeat('a', 1000); } } function produce($num) { $arr = array(); for ($i = 0; $i < $num; $i++) { $arr[] = new Test(); } $data = serialize($arr); $arr = unserialize($data); $data = json_encode($arr); $arr = json_decode($data); $data = msgpack_serialize($arr); $arr = msgpack_unserialize($data); $data = igbinary_serialize($arr); $arr = igbinary_unserialize($data); } produce(10000); ?> ```测试结果：
- 序列化性能：serialize() 24.611ms > msgpack_serialize() 32.687ms > igbinary_serialize() 36.012ms > json_encode() 132.142ms
- 反序列化性能：igbinary_unserialize() 12.141ms > msgpack_unserialize() 17.185ms > unserialize() 28.723ms > json_decode() 183.141ms
- 综合性能：igbinary 48.153ms > msgpack 49.872ms > serialize 53.334ms > json 315.283ms
测试结果并没有像传说中的那样，官方的序列化和反序列化函数性能与msgpack和igbinary两个第三方的扩展相差不大，而JSON性能非常差。
