README

It is often useful to be able to call a function or methods using named parameters. For example to only pass a different value for the nth default parameter.

PHP does not allow to do that, this library ought to change that.

Installation

composer require functional-php/named-parameters

Basic Usage

Say you have the following function:

function return_array($a, $b, $c) {
    return [$a, $b, $c];
}

Any of the following call is equivalent:

use function FunctionalPHP\NamedParameters\call_user_func_array_np;

// traditional call with positional arguments
call_user_func_array_np('return_array', [1, 2, 3]);

// named arguments in the correct order
call_user_func_array_np('return_array', ['a' => 1, 'b' => 2, 'c' => 3]);

// named arguments in random order
call_user_func_array_np('return_array', ['c' => 3, 'a' => 1, 'b' => 2]);
call_user_func_array_np('return_array', ['c' => 3, 'b' => 2, 'a' => 1]);

Testing

You can run the test suite for the library using:

composer test

A test report will be available in the reports directory.
