# ReflectionFunction::invokeArgs

(PHP 5 >= 5.1.2, PHP 7)

ReflectionFunction::invokeArgs — Invokes function args

### Description

public ReflectionFunction::invokeArgs ( array `$args` ) : mixed

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

Returns the result of the invoked function

### 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.
