How can ReflectionClass be used to check if a class implements an interface in PHP?

To check if a class implements an interface in PHP, you can use the ReflectionClass class to inspect the class and check if it implements the specified interface. This can be useful when you need to dynamically determine if a class adheres to a specific interface before using it in your code. 

<?php
// Create a new ReflectionClass instance for the class you want to check
$reflectionClass = new ReflectionClass('ClassName');

// Check if the class implements the specified interface
if ($reflectionClass->implementsInterface('InterfaceName')) {
    echo 'Class implements InterfaceName';
} else {
    echo 'Class does not implement InterfaceName';
}
?>
