php操縱mysql的類（與odbc相對應）

class mysql_db

{
var $host="127.0.0.1";
var $user="root";
var $passwd="";
function connect()
{

$con=mysql_connect($this->host,$this->user,$this->passwd);
if(!$con)
{
echo "mysql is not connect!".mysql_error()."
";
exit();
}
$select=mysql_select_db("soohuo");
if(!$select)
{
echo "select datebase error";
}
return $con;
}
function query($con,$sql)
{
if(empty($con))
{
echo "mysql connect success value is not null!
";
exit();
}
if(empty($sql))
{
echo "mysql sql value is not null!
";
exit();
}

$result=mysql_query($sql,$con);
/*
if(!$result)
{
echo "mysql sql error!
";
exit();
}
*/
return $result;
}
function fetch_row($result)
{
if(empty($result))
{
echo "mysql query success is null!
";
exit();
}
$row=mysql_fetch_row($result);
return $row;

}
function close($con)
{
if(empty($con))
{
echo "odbc connect is not null!
";
exit();
}
mysql_close($con);
}
}
?>
不做解釋了，很好理解的
使用中的真實情況是同時串連2個庫，我一個是mysql一個是oracle，我用這2個類完成的
