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.

You can move your code from your development system to a live server without needing to go through and edit/remove the settings. You can change the settings at a single point without searching through and editing the settings in a bunch of files.By putting them in your code, they won’t cause php parse errors to be reported and displayed/logged for the file they are in since your code never runs for this type of error to even cause the settings to take effect.
