PHP中的序列化方法性能对比

对比以下四个方法

1、json_encode
序列化后可阅读&＃xff0c;多语言通用协议。2、serialize
序列化后可阅读&＃xff0c;非通用协议&＃xff0c;只能用在PHP。3、swoole_serialize
序列化后不可阅读&＃xff0c;非通用协议&＃xff0c;只能用在PHP。4、msgpack
序列化后不可阅读&＃xff0c;多语言通用协议。


PHP版本 7.2.27

安装扩展

pecl install swoole_serialize-0.1.1
pecl install msgpackextension&＃61;msgpack
extension&＃61;swoole_serializephp --ri msgpack
php --ri swoole_serialize


使用 var_export($list, true) 原样导出数组

$arr &＃61; array(0 &＃61;>array(&＃39;id&＃39; &＃61;> 673,&＃39;userid&＃39; &＃61;> 209778,&＃39;activity_id&＃39; &＃61;> 27,&＃39;from_type&＃39; &＃61;> 1,&＃39;type&＃39; &＃61;> 127,&＃39;award_type&＃39; &＃61;> 1,&＃39;award_value&＃39; &＃61;> 5,&＃39;createtime&＃39; &＃61;> &＃39;2020-02-17 15:26:40&＃39;,),1 &＃61;>array(&＃39;id&＃39; &＃61;> 675,&＃39;userid&＃39; &＃61;> 4887823,&＃39;activity_id&＃39; &＃61;> 27,&＃39;from_type&＃39; &＃61;> 1,&＃39;type&＃39; &＃61;> 127,&＃39;award_type&＃39; &＃61;> 1,&＃39;award_value&＃39; &＃61;> 5,&＃39;createtime&＃39; &＃61;> &＃39;2020-02-17 20:32:17&＃39;,),2 &＃61;>array(&＃39;id&＃39; &＃61;> 680,&＃39;userid&＃39; &＃61;> 4987463,&＃39;activity_id&＃39; &＃61;> 27,&＃39;from_type&＃39; &＃61;> 1,&＃39;type&＃39; &＃61;> 127,&＃39;award_type&＃39; &＃61;> 1,&＃39;award_value&＃39; &＃61;> 5,&＃39;createtime&＃39; &＃61;> &＃39;2020-02-18 17:45:58&＃39;,),3 &＃61;>array(&＃39;id&＃39; &＃61;> 681,&＃39;userid&＃39; &＃61;> 4987463,&＃39;activity_id&＃39; &＃61;> 27,&＃39;from_type&＃39; &＃61;> 1,&＃39;type&＃39; &＃61;> 127,&＃39;award_type&＃39; &＃61;> 1,&＃39;award_value&＃39; &＃61;> 30,&＃39;createtime&＃39; &＃61;> &＃39;2020-02-18 17:50:28&＃39;,),4 &＃61;>array(&＃39;id&＃39; &＃61;> 686,&＃39;userid&＃39; &＃61;> 4987463,&＃39;activity_id&＃39; &＃61;> 27,&＃39;from_type&＃39; &＃61;> 1,&＃39;type&＃39; &＃61;> 127,&＃39;award_type&＃39; &＃61;> 1,&＃39;award_value&＃39; &＃61;> 30,&＃39;createtime&＃39; &＃61;> &＃39;2020-02-18 21:13:17&＃39;,),5 &＃61;>array(&＃39;id&＃39; &＃61;> 689,&＃39;userid&＃39; &＃61;> 4987463,&＃39;activity_id&＃39; &＃61;> 27,&＃39;from_type&＃39; &＃61;> 1,&＃39;type&＃39; &＃61;> 127,&＃39;award_type&＃39; &＃61;> 1,&＃39;award_value&＃39; &＃61;> 30,&＃39;createtime&＃39; &＃61;> &＃39;2020-02-19 00:10:00&＃39;,),6 &＃61;>array(&＃39;id&＃39; &＃61;> 694,&＃39;userid&＃39; &＃61;> 5026514,&＃39;activity_id&＃39; &＃61;> 27,&＃39;from_type&＃39; &＃61;> 1,&＃39;type&＃39; &＃61;> 127,&＃39;award_type&＃39; &＃61;> 1,&＃39;award_value&＃39; &＃61;> 5,&＃39;createtime&＃39; &＃61;> &＃39;2020-02-19 07:46:00&＃39;,),7 &＃61;>array(&＃39;id&＃39; &＃61;> 698,&＃39;userid&＃39; &＃61;> 5061307,&＃39;activity_id&＃39; &＃61;> 27,&＃39;from_type&＃39; &＃61;> 1,&＃39;type&＃39; &＃61;> 127,&＃39;award_type&＃39; &＃61;> 1,&＃39;award_value&＃39; &＃61;> 5,&＃39;createtime&＃39; &＃61;> &＃39;2020-02-19 12:42:48&＃39;,),8 &＃61;>array(&＃39;id&＃39; &＃61;> 699,&＃39;userid&＃39; &＃61;> 5061307,&＃39;activity_id&＃39; &＃61;> 27,&＃39;from_type&＃39; &＃61;> 1,&＃39;type&＃39; &＃61;> 127,&＃39;award_type&＃39; &＃61;> 1,&＃39;award_value&＃39; &＃61;> 5,&＃39;createtime&＃39; &＃61;> &＃39;2020-02-19 12:44:40&＃39;,),9 &＃61;>array(&＃39;id&＃39; &＃61;> 700,&＃39;userid&＃39; &＃61;> 5061307,&＃39;activity_id&＃39; &＃61;> 27,&＃39;from_type&＃39; &＃61;> 1,&＃39;type&＃39; &＃61;> 127,&＃39;award_type&＃39; &＃61;> 1,&＃39;award_value&＃39; &＃61;> 10,&＃39;createtime&＃39; &＃61;> &＃39;2020-02-19 12:45:40&＃39;,),

打印结果

由此可见&＃xff1a;

• swoole_pack 可将数据压缩的最小&＃xff0c;并且耗时最小&＃xff0c;但只能用在PHP语言&＃xff1b;
• msgpack_pack 耗时和 serialize 差不多&＃xff0c;但是数据压缩的更小&＃xff0c;并且多语言通用协议&＃xff1b;
• 如果数据存储在redis&＃xff0c;那么数据压缩比例是个很重要的指标&＃xff1b;
• serialize 和 json 相比&＃xff0c;占用存储空间大&＃xff0c;但耗时缩短了一倍&＃xff1b;
• 很明显反序列化的耗时是序列化的3倍左右&＃xff1b;
