使用哪个ClassNotFoundException？

Question

I am currently working on a Laravel project and I have a bit of code where I want to throw an exception if the class of the given type cannot be found.

$className = $type . 'Field';

if (!class_exists($className))
{
    // Throw exception
}

However my IDE (IntelliJ) is giving me auto-complete for 3 different classes belonging to different packages that all have the same name.

• Prophecy\Exception\Doubler\ClassNotFoundException
• Symfony\Component\Debug\Exception\ClassNotFoundException
• PhpSpec\Exception\Fracture\ClassNotFoundException

What is the difference between these and which one should I use in this scenario and why?

Answer 1

You should be using Symfony\Component\Debug\Exception\ClassNotFoundException.

Other two Exception handlings are for PhpSpec (Testing) and Prophecy (a mocking framework for phpspec).

Since you are trying to throw an exception for ClassNotFound, you should be using the Symfony Exception Handler.
