If you throw a general exception type, such as ErrorException, RuntimeException, or Exception in a library or framework, it forces consumers to catch all exceptions, including unknown exceptions that they do not know how to handle.

Instead, either throw a subtype that already exists in the Standard PHP Library, or create your own type that derives from Exception.

Noncompliant Code Example

throw new Exception();  // Noncompliant

Compliant Solution

throw new InvalidArgumentException();
// or
throw new UnexpectedValueException();

Exceptions

Generic exceptions in the signatures of overriding methods are ignored.

@Override
public void myMethod() throws Exception {...}

• CERT, ERR07-J. - Do not throw RuntimeException, Exception, or Throwable
