E_ERROR – the script cannot continue running and it is being terminated.Script execution won’t break and none of the errors will be thrown. E_NOTICE – the engine will just print out an informational message.E_PARSE – your syntax could not be parsed so your script won’t start.The script will continue to run without any errors thrown. E_STRICT – similar to E_DEPRECATED, this indicates that you are using a language feature that is not standard currently and might not work in the future.The script will definitely continue to run without errors. E_DEPRECATED – the interpreter will generate this type of warnings if you use a deprecated language feature. ![]() Here are some of the most commonly seen error codes: These constants are used when configuring PHP to hide or display errors of certain classes. PHP has a lot of constants that are used in relation to errors. Here is the output for the script: Notice: Undefined variable: someNotSetVariable on line 3Įrror caught: Call to undefined function someNoneExistentFunction () Trying to call a function that does not exist would result in a fatal error in earlier versions of PHP, but in PHP 7.1 you can catch it. ![]() This script will output a notice error for the attempt to access an invalid variable. Also, it provides a single point for catching both types of error in a single statement: getMessage() It only has one exception to notice, it cannot be implemented in userland classes directly, but only through extending the Exception class.
