php__calland__callStatic

时间:2021-07-01 10:21:17 帮助过:2人阅读

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
?>
