You can use this https://github.com/ajeetku/php-utility-Scripts/blob/master/load.php

you need to replace some basic values than you can dump your SQL DB

$filename = 'xxxxxx';
// MySQL host
$mysql_host = 'localhost';
// MySQL username
$mysql_username = 'xxxxxxx';
// MySQL password
$mysql_password = 'xxxxxxx';
// Database name

$mysql_database = 'xxxxxxx';

In your code, you are using php executable command

In that file you can see here All table Codes will be written problematically. It will be better for you. "BEST OF LUCK"
