Join them; it only takes a minute: Sign up MySQLi Error Handling? up vote 0 down vote favorite 1 I started using OO-MySQLi after procedural MySQL and I have a problem. In production environment my error handling system displays all errors as a custom page. MySQLi errors is an "error" too and I want catch them, but in documentation described only one way to do this: if (!$mysqli->query("SET a=1")) { exit('An error occurred: ' . $mysqli->error); } (just for example). This is a very bad way, because in my system I'm doing many things when error occurred, like logging, calling events, etc. Of course, I can extend mysqli class, for example: class myMysqli mysqli error handling { public function __construct(/* ... */) { parent::__construct(/* ... */); } public function query(/* .. */) { parent::query(/* ... */); if($this->errno !== 0) { // An error occurred } } } $mysqli = new myMysqli(/* ... */); $mysqli->query(/* ... */); But this way I need to extend almost ALL methods where error can occur. Moreover, MySQLi provides prepared statements (mysqli_stmt class) that has its own errors! Can you know a better way to handle MySQLi errors? Thank you in advance. Added About exceptions: Do I understand correctly that with exceptions I need do something like this: try { $mysqli->query(/* ... */); } catch (Exception $e) { // An error occurred } But this is similar to if(!$mysqli->query(/* ... */)) { // An error occured } What a difference? php architecture mysqli share|improve this question edited Feb 5 '13 at 16:47 asked Feb 5 '13 at 16:37 Max Stern 4841722 3 Look into exceptions –John Conde Feb 5 '13 at 16:38 1 Or just write a method that logs the error and shows a user friendly message, and call that method when an error occurs. –Green Black Feb 5 '13 at 16:40 @JohnConde yes, I can, but this way I need to surrond any MySQLi call with if/else block... –Max Stern Feb 5 '13 at 16:41 see php.net/manual/en/class.mysqli-sql-exception.php and the con
