Regarding namespaces:
Be sure to include fully namespaced class path:
<?php
forward_static_call_array(
array('NAMESPACE\CLASS_NAME', 'STATIC_METHOD'),
$params
);
(PHP 5 >= 5.3.0, PHP 7, PHP 8)
forward_static_call_array — 调用静态方法且参数作为数组传递
通过 callback
参数指定调用用户定义的函数或者方法。此函数必须在方法上下文中调用,不能在类外使用。它使用后期静态绑定。转发方法的所有参数都作为值和数组传递,类似于
call_user_func_array()。
返回函数的结果,失败时返回 false
。
示例 #1 forward_static_call_array() 示例
<?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(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";
}
?>
以上示例会输出:
B B more,args C other,args

one of academic example, when forward_static_call() can be useful
<?php
class A
{
public static function test()
{
var_dump('we were here');
return static::class;
}
}
class B extends A
{
public static function test()
{
return self::class;
}
}
class C extends B
{
public static function test()
{
$grandParent = get_parent_class(parent::class); // $grandParent is A
return forward_static_call([$grandParent, __FUNCTION__]); // calls A::test()
}
}
// prints
// string(12) "we were here"
// string(1) "C"
var_dump(C::test());
