php5 的对象新增了一个专用方法 __call(),这个方法用来监视一个对象中的其它方法。如果你试着调用一个对象中不存在的方法,__call 方法将会被自动调用。
__call() is triggered when invoking inaccessible methods in an object context.
__callStatic() is triggered when invoking inaccessible methods in a static context.
<?php class MethodTest { public function __call($name, $arguments) { // Note: value of $name is case sensitive. echo "Calling object method '$name' " . implode(', ', $arguments). "\n"; } /** As of PHP 5.3.0 */ public static function __callStatic($name, $arguments) { // Note: value of $name is case sensitive. echo "Calling static method '$name' " . implode(', ', $arguments). "\n"; } } $obj = new MethodTest; $obj->runTest('in object context'); MethodTest::runTest('in static context'); // As of PHP 5.3.0 ?>
