It is a good start! A few things:

You dont have the class instance variables x and y defined.

Code:

$this->x = $x;
$this->y = $y;

Below your database constant variables, put this

PHP Code:


			
var $x;
var $y;

Now your assignments above can actually place these variables, and if you wanted to access what you recently put through the last function call:

PHP Code:


			
$class = new math;

try {
    echo $class->plus(22, 55);
    echo 'We added ' . $class->x . ' + ' . $class->y;
}
catch(exception $e) {
    echo $e->getMessage();
}

?>

MysqlI rules, doesn't it? :D

PHP Code:


			
$db = new mysqli('localhost', 'user', 'pass', 'database');
$query = $db->query("SELECT col1, col2, col3 FROM table WHERE foo = 'bar'");

if ($query->num_rows > 0)
{
    while ($row = $query->fetch_array())
    {
        echo $row['col1'] . ' ' . $row['col2'] . ' ' . $row['col3'];
     }
}
else
{
    echo 'no records found';
}
