# forward_static_call

(PHP 5 >= 5.3.0, PHP 7)

forward_static_call — Call a static method

### 说明

forward_static_call ( callable `$function` [, mixed `$parameter` [, mixed `$...` ]] ) : mixed

Calls a user defined function or method given by the `function` parameter, with the following arguments. This function must be called within a method context, it can't be used outside a class. It uses the late static binding.

### 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`

  Zero or more parameters to be passed to the function.

### 返回值

Returns the function result, or `FALSE` on error.

### 范例

Example #1 forward_static_call() example

    <?php

    class 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
