PHP 忒聊 綴豖 梒 14. 濬迵勤砓 ヶ輛 The magic functions __sleep and __wakeup serialize() checks if your class has a function with the magic name __sleep. If so, that function is being run prior to any serialization. It can clean up the object and is supposed to return an array with the names of all variables of that object that should be serialized. The intended use of __sleep is to close any database connections that object may have, committing pending data or perform similar cleanup tasks. Also, the function is useful if you have very large objects which need not be saved completely. Conversely, unserialize() checks for the presence of a function with the magic name __wakeup. If present, this function can reconstruct any resources that object may have. The intended use of __wakeup is to reestablish any database connections that may have been lost during serialization and perform other reinitialization tasks. 綴豖 れ萸 ヶ輛 唗蹈趙勤砓ㄜ頗趕笢腔勤砓 奻珨撰 References inside the constructor
