# A trait to dynamically add methods to a class
[](https://packagist.org/packages/spatie/macroable)
[](https://packagist.org/packages/spatie/macroable)
This package provides a trait that, when applied to a class, makes it possible to add methods to that class at runtime.
Here's a quick example:
```php
$myClass = new class() {
use Spatie\Macroable\Macroable;
};
$myClass::macro('concatenate', function(... $strings) {
return implode('-', $strings);
});
$myClass->concatenate('one', 'two', 'three'); // returns 'one-two-three'
```
The idea of a macroable trait and the implementation is taken from [the `macroable` trait](https://github.com/laravel/framework/blob/master/src/Illuminate/Macroable/Traits/Macroable.php) of the [Laravel framework](https://laravel.com).
## Support us
[
](https://spatie.be/github-ad-click/macroable)
We invest a lot of resources into creating [best in class open source packages](https://spatie.be/open-source). You can support us by [buying one of our paid products](https://spatie.be/open-source/support-us).
We highly appreciate you sending us a postcard from your hometown, mentioning which of our package(s) you are using. You'll find our address on [our contact page](https://spatie.be/about-us). We publish all received postcards on [our virtual postcard wall](https://spatie.be/open-source/postcards).
## Installation
You can install the package via composer:
```bash
composer require spatie/macroable
```
## Usage
You can add a new method to a class using `macro`:
```php
$macroableClass = new class() {
use Spatie\Macroable\Macroable;
};
$macroableClass::macro('concatenate', function(... $strings) {
return implode('-', $strings);
});
$macroableClass->concatenate('one', 'two', 'three'); // returns 'one-two-three'
```
Callables passed to the `macro` function will be bound to the `class`
```php
$macroableClass = new class() {
protected $name = 'myName';
use Spatie\Macroable\Macroable;
};
$macroableClass::macro('getName', function() {
return $this->name;
};
$macroableClass->getName(); // returns 'myName'
```
You can also add multiple methods in one go by using a mixin class. A mixin class contains methods that return callables. Each method from the mixin will be registered on the macroable class.
```php
$mixin = new class() {
public function mixinMethod()
{
return function() {
return 'mixinMethod';
};
}
public function anotherMixinMethod()
{
return function() {
return 'anotherMixinMethod';
};
}
};
$macroableClass->mixin($mixin);
$macroableClass->mixinMethod() // returns 'mixinMethod';
$macroableClass->anotherMixinMethod() // returns 'anotherMixinMethod';
```
