php中serialize序列化与json性能测试的示例分析(2)

json :156
serialize :222
json_encode :0.1087498664856
json_decode :0.12652111053467
serialize :0.041656017303467
unserialize :0.040987968444824

测试结果看出json效率稍微比serialize差点，在php5.2可能会更差。应该是在php5.3之后，json扩展做了优化。

然后使用大数组做测试(代码放到最后，因为代码的数组比较长)：

测试结果：

json :5350
serialize :8590
json_encode :0.90479207038879
json_decode :1.753741979599
serialize :1.3566699028015
unserialize :1.3003630638123

我们可以看出，serialize比json差了快一个数量级。

总结：

1） 空间的比较

serialize在编码后大概是json的1.5倍。

原因：

serialize后字符串包含了子串的长度，这可能是速度方面的优化，但是测试结果不尽人意。 serialize有更加详细的类型区分，而json只有四种类型，并且是以简单的符号表示。 2）速度的比较 在较小数据的情况下， serialize比json快数量级。

在大数据量的情况下，json比serialize稍微差一点

3）处理对象
json无法处理对象方法等数据。

4）使用范围

序列化使用serialize，特别是对象的存储。这是其存在的意义。 与对象无关的数据存储可以使用json，如包含大量数字的数组等。 在前后端交互一般都使用JSON，另外，目前JSON只支持UTF-8编码的数据。
