forward_static_call_array — Call a static method and pass the arguments as array

说明

forward_static_call_array ( callable $function , array $parameters ) : mixed

Calls a user defined function or method given by the function parameter. This function must be called within a method context, it can't be used outside a class. It uses the late static binding. All arguments of the forwarded method are passed as values, and as an array, similarly to call_user_func_array().

参数

function

The function or method to be called. This parameter may be an array, with the name of the class, and the method, or a string, with a function name.

parameter

One parameter, gathering all the method parameter in one array.

Note:

Note that the parameters for forward_static_call_array() are not passed by reference.

返回值

Returns the function result, or false on error.

范例

Example #1 forward_static_call_array() 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(array('A', 'test'), array('more', 'args'));        forward_static_call_array( 'test', array('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
