A trait to dynamically add methods to a class
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:
$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 of the Laravel framework.

Installation
You can install the package via composer:
composer require spatie/macroable
Usage
You can add a new method to a class using macro
:
$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
$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.
$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';
