VALUES (...);"); $query->execute(array( '...' => $..., '...' => fatal error in php means $... )); } catch(Exception $e){ $GLOBALS['errors'][] = $e; } Here is the problem: When the connection to the DB is OK, everything works, When the connection fails but I don't use the DB, I have the $GLOBALS['errors'][] array and the script is still running afterwards, When the connection to the DB has failed, I get the following fatal error: Notice: Undefined variable: db in C:\xampp\htdocs[...]\test.php on line 32 Fatal error: Call to a member function prepare() on a non-object in C:\xampp\htdocs[...]\test.php on line 32 Note: Line 32 is the $query = $db->prepare(...) instruction. That is to say, the script crashes, and the try/catch seems to be useless. Do you know why this second try/catch don't works and how to solve it? Thanks for the help! EDIT: There are some really good replies. I've validated one which is not exactly what I wanted to do, but which is probably the best approach. php try-catch fatal-error share|improve this question edited Oct 17 '12 at 7:04 asked Oct 17 '12 at 6:35 Ploppe 61117 add a comment| 5 Answers 5 active oldest votes up vote 18 down vote accepted try/catch blocks only work for t

a useful technique (Google search for more info/examples)Unfortunately, php 7 catch fatal error set_error_handler() doesn’t catch fatal errors — as the PHP docs say:The following error types
Php Set_error_handler
cannot be handled with a user defined function: E_ERROR, E_PARSE, E_CORE_ERROR, E_CORE_WARNING, E_COMPILE_ERROR, E_COMPILE_WARNING, and most of E_STRICT raised http://stackoverflow.com/questions/12928487/php-try-catch-and-fatal-error in the file where set_error_handler() is called.Handily, I just discovered it’s possible to catch fatal E_ERROR errors and direct them to your custom error handler using a combination of register_shutdown_function() and error_get_last():set_error_handler('myErrorHandler');register_shutdown_function('fatalErrorShutdownHandler');function myErrorHandler($code, $message, $file, $line) { ...}function fatalErrorShutdownHandler(){ $last_error https://insomanic.me.uk/php-trick-catching-fatal-errors-e-error-with-a-custom-error-handler-cea2262697a2 = error_get_last(); if ($last_error['type'] === E_ERROR) { // fatal error myErrorHandler(E_ERROR, $last_error['message'], $last_error['file'], $last_error['line']); }}The key is that functions registered with register_shutdown_function() are called even on a fatal error - including out of memory errors. error_get_last() can then be used to detect whether we’re ending the script because of a fatal error, and pass the error info to your custom error handler if so.UncategorizedDevPHPBlockedUnblockFollowFollowingAndy YoungStartups.

An exception can be thrown, and caught ("catched") within PHP. Code may be surrounded in a try block, to facilitate the catching of potential exceptions. Each try must have at least one corresponding catch or finally block. The thrown object must be an instance of the Exception class or a subclass of Exception. Trying to throw an object that is not will result in a PHP
