PHP中serializen()与json_encode()的性能差异

结论

serializen的效率远高于json，特别是在反序列化方面。

实地测试

对同一个巨大数组分别进行10000次序列化和反序列化，得到如下测试结果：

测试环境
CPU: Intel i5-3317U

PHP: 7.0.12
SRV: Apache 2

json_encode    2.7458431720734 s
json_decode    7.1210720539093 s
serialize    1.899829864502 s
unserialize    0.033617973327637 s
