static 使用实例

自己以为解释static 解释比较好的列子，希望大家，也能通过它来理解

<?php// USING the same method in an instance and in a static context// If you want to have the same definition of a method that you// want to use both as static and as instance method, a classname control of $this// variable is needed. This tip can be used wether the caller context is not the same class typeclass A{ private $myProp = 'A'; public function myMethodA() { if(isset($this) && get_class($this) == __CLASS__) return $this->myProp; return 'C'; }}class B{ public $myProp = 'B'; public function myMethodB() { $a = new A; return $a->myMethodA().' ++++ '.A::myMethodA(); }}$b = new B();echo $b->myMethodB(); // output: A ++++ C// NOTE:// if you don't verify "&& get_class($this) == __CLASS__"// it will output A ++++ B, it seems that if a method is not marked as "static"// its scope would be the scope in which the function was called?>
