PHP The Good Parts

Make PHP JavaScript again

Overview

Adds support for JavaScript like prototypes on PHP classes. Now you can define prototypical methods on your PHP classes just like the magic of JavaScript. No more concrete class definitions! Now you can simply define that at runtime, or better yet, dynamically!

Installation

With Composer

composer config repositories.epfremme/php-the-good-parts vcs https://github.com/epfremmer/php-the-good-parts.git
composer require epfremme/php-the-good-parts

Examples

Basic Usage

class FooClass
{
    use Javascript;
}

FooClass::prototype()->my_method = function() {
    echo 'Hello JavaScript!!!';
    
    return $this; // $this equals the instance of FooClass
};

$foo = new FooClass();
$foo->my_method(); // outputs: 'Hello JavaScript!!!'

Runtime Definition

class FooClass
{
    use Javascript;
}

$foo = new FooClass();

if (!is_callable($foo->prototype()->my_method)) {
    $foo->prototype()->my_method = function() {
        echo 'Hello JavaScript!!!';
    };
}

$foo->my_method(); // outputs: 'Hello JavaScript!!!'

$bar = new FooClass();
$bar->my_method(); // still outputs: 'Hello JavaScript!!!'

External Scope Variables

class FooClass
{
    use Javascript;
}

$message = 'Hello JavaScript!!!';

FooClass::prototype()->my_method = function() use ($message) {
    echo $message;
};

$foo = new FooClass();
$foo->my_method(); // outputs: 'Hello JavaScript!!!'

Prototype Inheritance

class FooClass
{
    use Javascript;
}

class BarClass extends FooClass
{
    use Javascript;
}

FooClass::prototype()->my_method = function() {
    echo 'Hello JavaScript!!!';
};

$bar = new BarClass();
$bar->my_method(); // outputs: 'Hello JavaScript!!!' as defined on parent FooClass
