(PHP 5, PHP 7, PHP 8)

ReflectionFunction::invoke — Invokes function

Description

public ReflectionFunction::invoke(mixed ...$args): mixed

Invokes a reflected function.

Parameters

args

The passed in argument list. It accepts a variable number of arguments which are passed to the function much like call_user_func() is.

Return Values

Returns the result of the invoked function call.

Examples

Example #1 ReflectionFunction::invoke() example

<?php
function title($title, $name)
{
    return sprintf("%s. %s\r\n", $title, $name);
}

$function = new ReflectionFunction('title');

echo $function->invoke('Dr', 'Phil');
?>

The above example will output:

Dr. Phil

Notes

Note:

ReflectionFunction::invoke() cannot be used when reference parameters are expected. ReflectionFunction::invokeArgs() has to be used instead (passing references in the argument list).
