范例

Example #1 forward_static_call() example

<?phpclass A{    const NAME = 'A';    public static function test() {        $args = func_get_args();        echo static::NAME, " ".join(',', $args)." \n";    }}class B extends A{    const NAME = 'B';    public static function test() {        echo self::NAME, "\n";        forward_static_call(array('A', 'test'), 'more', 'args');        forward_static_call( 'test', 'other', 'args');    }}B::test('foo');function test() {        $args = func_get_args();        echo "C ".join(',', $args)." \n";    }?>

以上例程会输出：

B
B more,args 
C other,args
