This article mainly describes the PHP capture fatal error Error method, using Register_shutdown_function to catch fatal error errors, the need for friends can refer to the following
Fatal error generally does not need to be captured, but in a complex program, Fatal error can be difficult to handle if an occasional memory shortage occurs.
Like what. Fatal error when you fetch in the MySQL class. It's hard to pinpoint the real problem at this point.
PHP exception handling can be captured by Set_error_handler. But can only catch notice/warning level of error, for E_error is powerless.
Register_shutdown_function can solve the Set_error_handler deficiency.
By registering a good program with this function to end the callback function, you can catch errors that are not normally caught. Then the error is judged by Error_get_last. It is easy to find a problem that is difficult to locate.
The code is as follows:
function shutdown_function () { $e = Error_get_last (); Print_r ($e); } Register_shutdown_function (' shutdown_function ');
