php操纵mysql的类（与odbc相对应）

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);

}

}

?>

不做解释了，很好理解的

使用中的真实情况是同时连接2个库，我一个是mysql一个是oracle，我用这2个类完成的
