PHP Exceptions

This lesson is part of PHP · All levels

Summary

Exception is a PHP mechanism for handling errors when a program is running in a structured manner. You can block the risky code with try, catch the problem with catch, and guarantee clearance with finally. With the exception of failure, failure can be handled without making the program immediately stop completely.

Key points

Exception thrown with throw new
Block try to host code that risks error
Block catch catches and handles the exception thrown
The block finally always runs, whether there are exceptions or not.
