TraitConstantAccessedDirectly

A trait constant is accessed directly (e.g., MyTrait::CONST_NAME). In PHP, trait constants cannot be accessed directly; they must be accessed through a class that uses the trait.

Example

<?php
trait MyTrait {
    const NAME = 'trait';
}

class MyClass {
    use MyTrait;
}

// Error: accessing trait constant directly
echo MyTrait::NAME;

How to fix

Access the constant through a class that uses the trait:

<?php
trait MyTrait {
    const NAME = 'trait';
}

class MyClass {
    use MyTrait;
}

// Correct: access through the class
echo MyClass::NAME;
