# Dynamic Method Trait

:::{php:trait} DynamicMethodTrait
:::

## Introduction

Adds ability to add methods into objects dynamically. That's like a "trait"
feature of a PHP, but implemented in run-time:

```
$object->addMethod('test', function ($o, $args) {
    echo 'hello, ' . $args[0];
});
$object->test('world');
```

## Dynamic Method Arguments

When calling dynamic method first argument which is passed to the method will
be object itself. Dynamic method will also receive all arguments which are
given when you call this dynamic method:

```
$m->addMethod('sum', function ($m, $a, $b) {
    return $a + $b;
});
echo $m->sum(3, 5); // 8
```
