These are ways of utilizing the sqlite3 class. Which will you choose and why or better still which of these is the BEST

method 1 extending
<?php class MyDB extends SQLite3{
function __construct(){ $this->open('test.db');}
}
$db =new MyDB();
if(!$db){
echo $db->lastErrorMsg();
}else{
echo "Opened database successfully\n";
}
?>

method 2 wrapping
class MyDb {
function __construct(){
$data=new sqlite3();
$data->open('test.db');}
}
$db =new MyDB();
if(!$db){
echo $db->lastErrorMsg();
}else{
echo "Opened database successfully\n";
}
?>

Also i 'll be able to create functions that call the predefined functions without creating a new object instance of the sqlite3 class, this helps save ram space. Lets talk
