forward_static_call_array
(PHP 5 >= 5.3.0, PHP 7, PHP 8)
Call a callback with an array of parameters, preserving the current called class
Description
Calls a user defined function or method given by the callback parameter, with arguments passed as an array, similarly to call_user_func_array(). When called from within a method context and calling a method callback, it makes a forwarding call, so static:: inside the method resolves to the same called class as in the caller. This is useful for static method callbacks that should behave like self:: or parent::.
Unlike forward_static_call(), this function does not require an active class scope: calling forward_static_call() outside a class throws an Error, while this function does not.
Parameters
callbackThe 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.
argsThe parameters to be passed to the callback, as an array.
NoteTo pass a parameter by reference, the corresponding element in
argsmust be a reference.
Return Values
Returns the function result, or false on error.
Examples
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";
}
?>The above example will output:
B
B more,args
C other,args
