Register_shutdown_function Fatal Error
414 down vote favorite 181 I can use set_error_handler() to catch most PHP errors, but it doesn't work for fatal (E\_ERROR) errors, such as calling a function that doesn't exist. Is there another way to catch these errors? I am trying to call mail() for all errors and am running PHP 5.2.3. php fatal-error share|improve this question edited Dec 22 '13 at 19:26 aksu 3,94451434 asked Nov 10 '08

For example: function format_error( $errno, $errstr, $errfile, $errline ) { $trace = print_r( debug_backtrace( false ), true ); $content = "

VALUES (...);"); $query->execute(array( '...' => $..., '...' => $... )); } 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

of errors. For example, if you try to call a non-existing function from your script, PHP will probably render a white page on your production server… if your settings are like the one I defined in my article about error display. Using register_shutdown_function() For Fatal Errors The solution to this isn’t the cleanest I found, but it works. We’ll use the method register_shutdown_function(). Keep in mind that this method will be called after the end of each one of your scripts! So, don’t do any super costly operations in this custom handler, or all of your scripts will be slow. Add this piece of code to the previous script we made in the post : register_shutdown_function('fatalErrorHandler'); function fatalErrorHandler() { $last_error = error_get_last(); if ($last_error['type'] === E_ERROR) { errorHandler(E_ERROR, $last_error['message'], $last_error['file'], $last_error['line']); } } The 1st line is the line registering our custom 'shutdown function'. You can register as many function as you want with this function. For this example, we only need to register one handler that will check for fatal errors. The 4th line inside our custom shutdown handler is a piece of code that will get the last error that happened (if there was an error). The 5th line will check that the error is a fatal error. We don't want this handler to handle other types of errors because we already do this with our custom error_handler. The 6th line is where we call our custom error handler we made in the previous post, so that the same logic is reused. Conclusion That’s it! If
