Functionality:

This script uses ~80 URL requests and writes ~8000 arrays to a file (~50Mb-150Mb).

Performance:

The only goal is making this script as fast/efficient (performance) as possible. There are alternative methods (such as relevant question), which I'm not sure how to implement. Would you be so kind and review my modified working code?

Alternative getSymbols():

public static function getSymbols() {

     return array_map(function($line){ return str_getcsv($line, "t"); }, file(__DIR__ . self::SYMBOLS_PATH));

}

Entire Modified Code (Version II):

// local server and live

if($_SERVER['LOGNAME']==="NAME_OF_LOGNAME_GOES_HERE"){

  error_reporting(E_ALL);

}else{

  error_reporting(0);

}
