error handling - PHP: How to first log an exception and then report by mail? -

i handcrafted complex order process go online soon. first time, want informed errors occur, want them logged. answer suggests first log them , mail them more secure since mailing might fail. when catch exception, it's not being logged, , when don't catch it, can't send email.

my code:

// convert errors exceptions function exception_error_handler($errno, $errstr, $errfile, $errline ) {     throw new errorexception($errstr, 0, $errno, $errfile, $errline); } set_error_handler("exception_error_handler");  try {     // ... code might cause errors or throw exceptions } catch(exception $e) {     log(...); // how can make error being logged here?     mail(...); // afterwards send email     throw $e; // re-throw way, after mailing it, cause kills process. } 

sure, write 1 logging routine, guess php in clever way i'd use.

another thing great having control makes sure no more x error emails per hour sent out.

all in seems pretty common setup, couldn't find ready solution. or idea somehow stupid in hole?

the function error_log() automatically log message web server's error_log file. if prefer, can specify custom log file vs. default error_log file.

so can log simple error message in error_log this:

error_log("this error message"); 

or log exception message in /var/log/web_error_log:

} catch (exception $e) {     error_log($e->getmessage(), 3, '/var/log/web_error_log'); } 

see http://ca2.php.net/manual/en/function.error-log.php more details on error_log.
