If you cannot use the PDO extension. Or you are having trouble building your database class with prepared statements.
How to use for insert update, delete and insert:
$db = new database();
$db->query = "INSERT INTO blabla (name,date,number) VALUES(?,?,?)";
$db->params = array($name,$date,$number);
$db->type = 'ssi'; //s=string,i=integer
if($db->insert())
echo 'success';

$array = array();
$db = new database();
$db->query = "SELECT * FROM blabla WHERE id=? and someother=?";
$db->params = array($id,$other);
$db->type = 'is';
$r = $db->fetch();
//$r[0]['id'] for row 1
//$r[0]['name'] for row 1
//$r[1] .... For row 2
//$r[2] .... For row 3
//etc...
