In PHP, how do I validate traits with built-in functions?

In PHP, you can validate traits by checking if a class uses a particular trait using the built-in `trait_exists()` function. This function allows you to ensure that the specified trait is defined and usable within your class.

Example of Validating Traits in PHP


        <?php
        trait MyTrait {
            public function myTraitMethod() {
                return "Method from MyTrait";
            }
        }

        class MyClass {
            use MyTrait;
        }

        // Checking if the trait exists
        if (trait_exists('MyTrait')) {
            echo "Trait MyTrait is valid and exists!";
        } else {
            echo "Trait MyTrait does not exist.";
        }
        ?>
