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

### Changelog

Version | Description
--- | ---
8.0.0 | `args` keys will now be interpreted as parameter names, instead of being silently ignored.

### Examples

Example #1 ReflectionFunction::invokeArgs() example

    <?phpfunction 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

    <?phpfunction 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.
