Regarding namespaces:
Be sure to include fully namespaced class path:
<?php
forward_static_call_array(
array('NAMESPACE\CLASS_NAME', 'STATIC_METHOD'),
$params
);
forward_static_call_array
(PHP 5 >= 5.3.0, PHP 7)
forward_static_call_array — Call a static method and pass the arguments as array
Descrierea
Calls a user defined function or method given by the callback
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().
Parametri
-
callback -
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.
Notă:
Note that the parameters for forward_static_call_array() are not passed by reference.
Valorile întoarse
Returns the function result, or false on error.
Exemple
Example #1 forward_static_call_array() 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(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";
}
?>
Exemplul de mai sus va afișa:
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());
