Php Set_error_handler
it is possible to catch Fatal Errors through a shutdown function which cannot be caught using set_error_handler(). However, I couldn't find out how to determine if the shutdown has occured due to a fatal error or due to the script reaching its end. Additionally, the debug backtrace functions seem to be defunct in the shutdown function, making it pretty worthless for logging the stack trace where the Fatal Error occured. So my question is: what is fatal error in php what's the best way to react on Fatal Errors (especially undefined function calls) while keeping the ability to create a proper backtrace? php error-handling fatal-error share|improve this question asked Dec 10 '10 at 15:55 ThiefMaster♦ 188k38353466 add a comment| 4 Answers 4 active oldest votes up vote 40 down vote accepted This works for me: function shutdown() { $error = error_get_last(); if ($error['type'] === E_ERROR) { // fatal error has occured } } register_shutdown_function('shutdown'); spl_autoload_register('foo'); // throws a LogicException which is not caught, so triggers a E_ERROR However, you probably know it already, but just to make sure: you can't recover from a E_ERROR in any way. As for the backtrace, you can't... :( In most cases of a fatal error, especially Undefined function errors, you don't really need it. Pinpointing the file/line where it occured is enough. The backtrace is irrelevant in that case. share|improve this answer edited Dec 10 '10 at 16:22 answered Dec 10 '10 at 16:05 netcoder 43k985123 add a comment| up vote 5 down vote One way to distinguish between fatal error and proper application shutdown with the register_shutdown_function is to define a constant as the last line of your program, and then check if the constant is defined: function fatal_error() { if ( ! defined(PROGRAM_EXECUTION_SUCCESSFUL)) { // fatal error has occurred } } register_sh

Php Set_exception_handler
set_error_handler() doesn’t catch fatal errors — as the PHP docs say:The following error types php error_get_last 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/4410632/handle-fatal-errors-in-php-using-register-shutdown-function 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.
