save echo "User saved."; return true; } } It uses another class named Validator, which we put in validator.php: class Validator { public function validate_email($email) { if (!filter_var($email, FILTER_VALIDATE_EMAIL)) { throw In this case we will catch a DatabaseException and only that catch block will get executed.

    I have implemented a pre_system hook on my codeigniter applications so that I can get my fatal errors through emails, and this helped me finding bugs that were not reported (or file_exists($file)  || ! getMessage() − message of exception getCode() − code of exception getFile() − source filename getLine() − source line getTrace() − n array of the backtrace() getTraceAsString() − formated string of trace Plus many times calls were interspersed with set_error_handler calls and handlers.

    Since then my ErrorHandler is capped at 100 emails per webserver. –Bob Fanger Sep 23 '09 at 8:12 14 That's not true. In debug situations i also have an exception handler that outputs an asp.net like page. It’s a more language-syntax-integrated way of doing error handling than writing custom error handling functions.Exceptions are represented in PHP by the class Exception. Or you can use a site-wide error handling setting as well.

    If an exception is not caught, a PHP Fatal Error will be issued with an "Uncaught Exception ..." message, unless a handler has been defined with set_exception_handler(). This is like an E_WARNING set by the programmer using the PHP function trigger_error() 512 9 E_USER_NOTICE User-generated notice. else : ?> NULL

    Once we call the save() method, it will utilize the Validator class for checking the email format, which might return an exception: include('user.php'); include('validator.php'); $u = new User(); $u->name = 'foo'; In real world scenarios every clock cycle counts. Each level is represented by an integer value and named constant which can be used by the programmer. This allows you to specify what Exception error is handled where (in a clean and simple way) at the point in your code where it makes the most sense.

    Or you might want to do something (such as logging) with each Exception that is thrown from a certain region (catch it, pass it to the logging function, then rethrow it). PHP provides a few configuration directives related to logging and displaying errors.
