Fatal error generally does not need to be captured, but in a complex program, if Fatal errors caused by occasional insufficient memory are difficult to handle. For example, fatal errors occur when fetching in the MySQL class. At this time, it is difficult to locate the real problem.

register_shutdown_function can solve the shortcomings of set_error_handler.

Register the program end callback function through this function, and you can Capture errors that cannot be caught normally. Then use error_get_last to judge the errors. It is easy to find problems that are difficult to locate.

The code is as follows:function shutdown_function() {

print_r($e);
}
register_shutdown_function('shutdown_function');
