But is that an acceptable or standard practice? From what I've read, that would halt the execution and make it jump straight to the catch block (just as a failed if statement will go to the else block), where I could then output the error message. I have been reading about try/catch and have been thinking of putting all of my code inside a try statement, then let the code run sequentially without any if/else blocks and if something fails just throw an exception. This doesn't seem like a smart way of doing things. The way I'm doing things works, but it's very cumbersome and tedious for what is probably obvious: suppose that I call a function somewhere in the middle of my code, or want to check the value of a variable, or verify a DB query returned a valid result, and if it fails I want to output an error? I would have to make another if/else block and move all of the code inside the new if block. display whatever error occurred on the page $error = 'something is not a valid value' $error = 'something is most definitely not OK.' ': '.$this->getMessage().Right now my pages look something like this: if($_GET = 'somevalue') Lets try to throw an exception without catching it: If an exception is not caught, a fatal error will be issued with an "Uncaught PHP will try to find the matching "catch" block. When an exception is thrown, the code following it will not be executed, and To jump to another place in the code at a specified point. Note: Exceptions should only be used with error conditions, and should not be used We will show different error handling methods: Depending on the situation, the handler may then resume the execution from the saved code state, terminate the script execution or continue the script from a different location in the code.The code execution will switch to a predefined (custom) exception handler function.This is what normally happens when an exception is triggered: With PHP 5 came a new object oriented way of dealing with errors.Įxception handling is used to change the normal flow of the code execution ifĪ specified error (exceptional) condition occurs.
