The class_uses Function

The class_uses function returns an array with the names of traits used by the specified class or object. The function takes one mandatory parameter - a class or object, and one optional parameter that determines whether to include traits from parent classes.

Syntax

class_uses(object|string $class, bool $autoload = true): array

Example

Let's create several traits and a class that uses them:

<?php
	trait TraitA {
		public function methodA() {}
	}
	
	trait TraitB {
		public function methodB() {}
	}
	
	class MyClass {
		use TraitA, TraitB;
	}
	
	$res = class_uses('MyClass');
	print_r($res);
?>

Code execution result:

[
	'TraitA' => 'TraitA',
	'TraitB' => 'TraitB'
]

Example

Let's check traits for an object:

<?php
	$obj = new MyClass();
	$res = class_uses($obj);
	print_r($res);
?>

Code execution result:

[
	'TraitA' => 'TraitA',
	'TraitB' => 'TraitB'
]

Example

Working with inheritance:

<?php
	class ParentClass {
		use TraitA;
	}
	
	class ChildClass extends ParentClass {
		use TraitB;
	}
	
	$res = class_uses('ChildClass');
	print_r($res);
?>

Code execution result:

[
	'TraitB' => 'TraitB'
]
