//How to connect and get results from any mysql table


$DB = new DB_MYSQL('localhost','3306','root','password', 'mysql'); //connect to database (host, port, user, password, database)

//$DB = new DB_MYSQL('localhost','3306','root','password', 'mysql', 2); //connect to database with debug mode = 2


$query1 = $DB->query('SELECT host FROM user'); //send query
$query2 = $DB->query('SELECT password FROM user'); //send query
$query3 = $DB->query('SELECT * FROM help_topic'); //send query :)
$query4 = $DB->query('SELECT user FROM user'); //send query :)



#First option -> u use only $DB->fetch() and $buffer will get result from LAST query


   
while($buffer = $DB->fetch()) //fetch result to array - basic method
       
{
    echo
$buffer['user'].'<br>'; //where 'user' is a name of desired row in table
       
}

#Second option -> you can choose, from which query you want to get result $DB->fetch($query2)


   
while($buffer = $DB->fetch($query2))

        {
    echo
$buffer['password'].'<br>';
