ReflectionFunction::invokeArgs

(PHP 5 >= 5.1.0, PHP 7)

Invokes function args

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.

Returns:

Returns the result of the invoked function

Notes:

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

Examples:

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

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)
}
