forward_static_call_array
Call a callback with an array of parameters, preserving the
current called class
Description
mixed forward_static_call_array(callable $callback, array $args)
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::.
Note:
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
-
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.
-
args
-
The parameters to be passed to the callback, as an array.
Note:
To pass a parameter by reference, the corresponding element in
args must be a reference.
Return Values
Returns the function result, or false on error.
Examples
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";
}
?>
The above example will output:
B
B more,args
C other,args
