php - Proper way to handle unavoidable warnings -


there're many old procedural functions can emit warnings due error conditions happen on regular operation, e.g.: fopen(), mail(), oci_connect()...

  • the most obvious workaround said expensive , has side effect of hiding everything:

    echo @file_get_contents(oops_forgot_dollar);

  • a custom error handler looks overkill:

    private function warninghandler($errno, $errstr, $errfile, $errline/*, array $errcontext*/){     if(error_reporting()===0){         return false;     }else{         throw new errorexception($errstr, 0, $errno, $errfile, $errline);     } }  // ....  try{     set_error_handler('csvloader::warninghandler', e_warning);     $this->fp = fopen($filename, 'r');     restore_error_handler();      $this->readdata(); }catch(errorexception $e){     restore_error_handler();     throw new csvloaderexception("could not open file: {$e->getmessage()}"); }

  • letting warning pass through annoying in configured server:

    • in developement display in middle of , can break things
    • in production flood error log useless data

what's recommended practice? how php gurus handle it?

the error_log not useless data

i find it's easy enough keep on top of if there's hourly cron job emails contents of error_log file .....

soon you'll have added in appropriate checks code base , problems sorted.

i have model ( article ) field (the name type ) of type enum('source', 'translated') , return 1 article ordered type field. source articles should returned before translated articles. like: article.findone(order: [ { type: [ 'source', 'translated' ] } ]); unfortunately there appears no built-in solution sorting enums. instead have sort by case , couldn't find documentation on how sequelize. what conventional approach here? sorting case hard in sequelize, sort field (the second answer in linked post) should possible: order: sequelize.fn('field', sequelize.col('type'), 'source', 'translated') it's supported mysql far know though
