本文实例讲述了PHP串行化与反串行化。分享给大家供大家参考，具体如下：
对象也是一种在内存中存储的数据类型，他的寿命通常随着生成该对象的程序的终止而终止。有时候可能需要把对象的状态保存下来，需要时再将其回复。串行化是把每个对象转化为二进制字符串。

name = $name;
$this->sex = $sex;
$this->age = $age;
}
function say() {
echo $this->name . "在说话
"; } function run() { echo "在走路·
"; } //串行化的时候自动调用，成员$sex被忽略，只串行$name,$age function __sleep() { $arr = array("name","age"); return $arr; } //反串行化时自动调用 function __wakeup() { $this->age = 33; } } class Student extends Person { var $school; function __construct($name = "",$age = 22,$school="") { parent::__construct($name,$sex,$age); $this->school = $school; } function study() { echo $this->name."正在".$this->school."学习
"; } } class Teacher extends Student { var $wage; function teaching() { echo $this->name."正在".$this->school."教学，每月工资为".$this->wage."
"; } //如果调用了不存在的方法，将会自动调用__call()，不会报错 function __call($functionName,$args) { echo "函数名：".$functionName; print_r($args); echo "
"; } } $teacher1 = new Teacher("kaifu","男",22); $teacher1->school = "edu"; $teacher1->wage = 4000; $teacher1->say(); $teacher1->study(); $teacher1->teaching(); $teacher1->hello(1,2,3); ?>
