PHP - Error and Exception Handling

Which of the following is the correct way to declare a custom exception class named MyError in PHP?

Aclass MyError extends Error {}

Bclass MyError implements Exception {}

Cclass MyError extends Exception {}

Dclass MyError inherits Exception {}

Step-by-Step Solution

Solution:

Step 1: Recall PHP syntax for custom exceptions
Custom exceptions extend the built-in Exception class using the keyword extends.
Step 2: Check each option
class MyError extends Exception {} correctly uses extends Exception. class MyError implements Exception {} wrongly uses implements, which is for interfaces. class MyError extends Error {} extends Error, which is a different base class. class MyError inherits Exception {} uses invalid syntax inherits.
Final Answer:
class MyError extends Exception {} -> Option C
Quick Check:
Custom exception syntax = extends Exception [OK]

Quick Trick: Use 'extends Exception' to create custom exceptions [OK]
