ReflectionFunction::invokeArgs — Invokes function args

Description

public mixed ReflectionFunction::invokeArgs ( array $args )

Invokes the function and pass its arguments as array.

Parameters

args

The passed arguments to the function as an array, much like call_user_func_array() works.

Return Values

Examples

Example #1 ReflectionFunction::invokeArgs() example

<?php function title($title, $name) {     return sprintf("%s. %s\r\n", $title, $name } $function = new ReflectionFunction('title' echo $function->invokeArgs(array('Dr', 'Phil') ?>

The above example will output:

Dr. Phil

Example #2 ReflectionFunction::invokeArgs() with references example

<?php function get_false_conditions(array $conditions, array &$false_conditions) {     foreach ($conditions as $condition) {         if (!$condition) {             $false_conditions[] = $condition;         }     } } $function_ref     = new ReflectionFunction('get_false_conditions' $conditions       = array(true, false, -1, 0, 1 $false_conditions = array( $function_ref->invokeArgs(array($conditions, &$false_conditions) var_dump($false_conditions ?>

The above example will output:

array(2) { [0]=> bool(false) [1]=> int(0) }

Notes

Note: If the function has arguments that need to be references, then they must be references in the passed argument list.
