To begin, it's important to note that though MySQL doesn't have classic try catch in PHP statements, it does provide conditions, which are similar to Exceptions. And an exception that isn't caught anywhere in your application causes an error, which stops the program from running. If a thrown exception is caught someplace in your application, program execution resumes from where the exception was caught. As a result, we can claim that exceptions are recoverable, whereas certain errors are not.

However, some faults are unrecoverable and cause the software to stop working.Įxceptions, on the other hand, are intentionally thrown by the code and are meant to be detected at some point in your application. You will be able to control faults in this manner. It is vital to realize that exception handling and error handling are not the same thing. All exceptions are instances of the Exception base class, which we can modify to add our own custom exceptions.
