What are the main error types in PHP and how do they differ?
In PHP there are three main type of errors:
Notices – Simple, non-critical errors that are occurred during the script execution. An example of a Notice would be accessing an undefined variable.
Warnings – more important errors than Notices, however the scripts continue the execution. An example would be
include() a file that does not exist.
Fatal – this type of error causes a termination of the script execution when it occurs. An example of a Fatal error would be accessing a property of a non-existent object or
require() a non-existent file.
Understanding the error types is very important if you are new to programming because they help you understand what is going on during the development, and they will help you know what you should look for in the code during debugging.
