Execute a PHP Script

I have a script that imports data from one system to another so it is a system that requires time since it passes almost 300,000 records.

For this I have created a class with PHP using the laravel framework but I get an error 504 when executing the script

  

Gateway Timeout The gateway did not receive a timely response from the   upstream server or application.

     

Apache / 2.4.29 (Ubuntu) Server at local Port 80

That's why what I do is, in the constructor class, set a series of parameters of the php, but with all that I keep getting the error.

The class code is just like this:

class CarsController extends Controller
{

function __construct() {
    ini_set('max_execution_time', 999999);
    ini_set('max_input_time', 999999);
    ini_set('default_socket_timeout', 999999);
    ini_set('memory_limit','4096M');

    parent::__construct();
}


public function readMigration()
{
//Realizar las acciones SQL
}
}

The php configuration uses php7.2-fpm and I have the following

; Default timeout for socket based streams (seconds)
; http://php.net/default-socket-timeout
default_socket_timeout = 60
