Do I need a php mysql connection in each function that uses database?

Question

I am creating a php restful API and currently I have the database connection information in each function.

//Connect To Database
    $hostname=host;
    $use         


        

Answer 1

Why won't you move out the connection information into config and the call to mysql_connect into some factory?

E.g.

class ConnectionFactory {
    public static MysqlConnection CreateConnection() {
        $connection = mysql_connect(Config::$host, Config::$port etc);
        mysql_select_db($connection, Config::$schema);
        return $connection;
    }
}

and then in your code

$connection = ConnectionFactory::CreateConnection();
mysql_query($connection, $sqlApiAccess) or die('Error, insert query failed');
