How can I log fatal errors in PHP?
It is not possible to handle fatal errors using a custom error handler.
The best solution is simply enabling error logging (e.g. to syslog) in your php.ini and then using a tool like logcheck/logsentry to receive regular emails about unusual syslog entries.
Instead of syslog PHP can also log errors to a file — simply have a look at the error logging options of php.ini.
log_errors = On error_log = syslog error_log = /path/to/some/folder/phperrors.log Obviously you only want to use one of the error_log lines.
There is a way to cope with your task and actually you can set a custom error handler on fatal errors.
ini_set('error_reporting', E_ERROR); register_shutdown_function("fatal_handler"); function fatal_handler() < $error = error_get_last(); // Do whatever you want with this error. For example: YourDBApplicationLayer::writeFatal($error); >Now in PHP 7 it is possible to catch fatal errors:

Is it possible in PHP to prevent «Fatal error: Call to, Some years back I started using this same strategy, but I abandoned it because it interferes with most IDE’s ability to do static analysis. Being able to have an IDE tell me all the places in my code base which call certain method is very valuable, and when doing dynamic method calls (like this sample does), they can no longer …
How to email PHP Fatal Errors only?
set_error_handler allows you to specify a user-defined error handling function for deciding what to do with certain (but only non-fatal) errors. You can then handle specific types of errors in any fashion you deem necessary, for example notifying a system administrator via email, or saving to a specific log file. See: PHP Doc for further details.
With regards to your request you could the following approach:
function myErrorHandler($errno, $errstr, $errfile, $errline) < if (!(error_reporting() & $errno)) < // This error code is not included in error_reporting return; >switch ($errno) < case E_USER_ERROR: case E_ERROR: case E_COMPILE_ERROR: echo "My ERROR [$errno] $errstr
\n"; echo " Fatal error on line $errline in file $errfile"; echo ", PHP " . PHP_VERSION . " (" . PHP_OS . ")
\n"; echo "Aborting.
\n"; emailErrorFunction($errno,$erstr,$errfile,$errline); exit(1); break; default: echo "Unknown error type: [$errno] $errstr
\n"; break; > /* Don't execute PHP internal error handler */ return true; > // Report all errors error_reporting(E_ALL); // User a custom error handler to print output set_error_handler( 'myErrorHandler' ); As that error-handling does not work for Fatal Errors (Parse errors, undefined functions etc.), you need to tape this with register_shutdown_function as outlined in a related question:
Alerternatively you can use (if you have shell access) a log watcher shell script. This allows to catch any error, including parse errors (which you cannot catch with register_shutdown_function).
#!/bin/bash tail -f /path_to_error_log/php_error.log|while read LINE;do if grep -q "PHP (Parse|Fatal) error" <(echo $LINE); then ( echo "From: server@example.com" echo "To: me@example.com" echo "Subject: PHP Error" echo $LINE ) | sendmail -t fi done This is imho more harmless because this is just a side process, and allows you to rely on other technology (shell script or whatever), in case errors happen because of php environment itself, you will still be notified.
Init following function inside your php file.
register_shutdown_function('mail_on_error'); //inside your php script /** If any file having any kind of fatal error, sln team will be notified when cron will become fail : following is the name of handler and its type E_ERROR: 1 | E_WARNING: 2 | E_PARSE: 4 | E_NOTICE: 8 */ function mail_on_error() < global $objSettings; $error = error_get_last(); //print_r($error); if ($error['type'] == 1) < // update file path into db $objSettings->update_records($id=1,array('fatal_error' => json_encode($error))); $exception_in_file_path = __FILE__; fatal_error_structure($exception_in_file_path); >// end if >// end mail_on_error fatal_error_structure should be defined on some global location. like function.inc.php .

PHP ErrorException
Introduction
PHP's Exception class implements the Throwable interface. ErrorException class extends the Exception class. ErrorException is meant to be explicitly thrown when you want to catch and handle errors that would otherwise be ignored, such as Notices or Warnings.
PHP core consists of following predefined error constants
| Value | Constant | Description |
|---|---|---|
| 1 | E_ERROR | Fatal run-time errors. |
| 2 | E_WARNING | Run-time warnings (non-fatal errors). |
| 4 | E_PARSE | Compile-time parse errors. |
| 8 | E_NOTICE | Run-time notices. |
| 16 | E_CORE_ERROR | Fatal errors that occur during PHP's initial startup. |
| 32 | E_CORE_WARNING | Warnings (non-fatal errors) that occur during PHP's initial startup. |
| 64 | E_COMPILE_ERROR | Fatal compile-time errors. |
| 128 | E_COMPILE_WARNING | Compile-time warnings (non-fatal errors). |
| 256 | E_USER_ERROR | User-generated error message. |
| 512 | E_USER_WARNING | User-generated warning message. |
| 1024 | E_USER_NOTICE | User-generated notice message. |
| 2048 | E_STRICT | If Enabled PHP suggests changes to your code to ensure interoperability and forward compatibility of your code. |
| 4096 | E_RECOVERABLE_ERROR | Catchable fatal error. |
| 8192 | E_DEPRECATED | Run-time notices. |
| 16384 | E_USER_DEPRECATED | User-generated warning message. |
| 32767 | E_ALL | All errors and warnings, E_STRICT |
In addition to properties and methods inherited from Exception class, ErrorException class introduces one property and one method as follows −
protected int severity ; final public getSeverity ( void ) : int
The severity of exception is represented by integer number associated with type of error in above table
ErrorException example
In following script, a user defined function errhandler is set as Error handler with set_error_handler() function. It throws ErrorException when fatal error in event of file not found for reading is encountered.
Example
throw new ErrorException("Fatal Error:No such file or directory", 0, E_ERROR); > set_error_handler("errhandler"); /* Trigger exception */ try < $data=file_get_contents("nofile.php"); echo $data; >catch (ErrorException $e)< echo $e->getMessage(); > ?> Above example displays following output
Output
Fatal Error:No such file or directory
