There is a way to cope with your task and actually you can set a custom error handler on fatal errors.
You can do it this way:
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); }

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.

You should be able to handle a fatal error with register_shutdown_function()

@SebastiánGrignoli: There is no clean way to detect if there was an error in that function.

<?php function cleanup(){ print_r(error_get_last()); } register_shutdown_function("cleanup");asdfasdf();Sebastián Grignoli
I agree it's not 100% clean, but it's enough for logging the error, I think.

Re "It is not possible to handle fatal errors using a custom error handler.": Did it change with PHP 7 or not?
Now in PHP 7 it is possible to catch fatal errors:
try { ggggg(); // <---- make a fatal error } catch(Throwable $e) { var_dump($e); } 1 Comment

In PHP 7 there's a new and very useful
Throwable class, which finally uniforms errors and exceptions, but to implement it you must typecast the error/exception object to Throwable: try { ggggg(); } catch(\Throwable $e) { var_dump($e); }You could have all your base classes belong to a super-class utilizing method overloading:
class Base { public function __call($name) { MyLog::logError(...); trigger_error("Function ".get_class($this)."::$name doesn't exist", E_USER_ERROR); } } Attempts to invoke non-existing methods of classes derived from Base would be ultimately handled by Base::__call(). For static methods, accordingly, there's __callStatic() (as of PHP 5.3).

What does the strikeout for "base" mean? Is it an old revision? - can it be deleted? Or something else?
Linus Kleen
"All your base." Get it?
Something like:
if(!method_exists($obj, 'method')){ $db->log('What you want to log'); //log in your DB error_log('message');//Write to php's error log }
