"Modern versions of PHP support error handling through the use of exceptions. PHP has several different predefined types of exceptions and also allows you to define your own exception types by creating new classes that inherit from the generic Exception class. PHP uses the standard try-catch-finally control structure to handle exceptions and allows you to throw your own exceptions.\n\nThough PHP defines several different types of exceptions, we’ll only cover the generic Exception class. We can throw an exception in PHP by using the keyword throw and creating a new Exception with an error message.\n\nthrow new Exception(\"Something went wrong\");\n\nBy using a generic Exception, we can only attach a message to the exception (which can be printed by code that catches the exception). If we want more fine-grained control over the type of exceptions, we need to define our own exceptions."
