序列化对象销毁,触发__destruct,判断op值如果强等于“2”则把op重置为“1”,注意这里的“2”是字符串,然后把content置空,执行process函数,进入process函数后先判断op,op等于“1”进入write函数,op等于“2”进入read函数(write函数实现一个文件写入的功能,read函数实现一个文件读取的功能)...

Note: If the method is called several times, you can use the following syntax to return different values for each call:$prophecy->read('123')->willReturn(1, 2, 3); This feature is actually not recommended for most cases. Relying on the order of calls for the same arguments tends to ...
