function Query(string query) ;

This function has one parameter that is the mysql query. Because the mysql language is very complex I think that for this simple class is enought to keep this simple mode of access.

EX: $db->Query('SELECT * FROM `table`');

by default is set to 1

This function get the query string, replace the '??' with the values from the second parameter after these values was modified with mysql_real_escape_string. After that the new resulted string is sent the the Query function. It can be used either the Query function but this one is more safe against the SQL Injection attack.

EX: $db->Insert('INSERT INTO `table` (`id`, 'username', `description`) VALUES ('', '??', '??');', array('ciprian', 'this " is my descrption'));
