I have written this code:
class db{
var $_miInstancia;
function db (){
// funcion que se conecta con la BBDD
static $miInstancia;
$this->_miInstancia=&$miInstancia;
$result = @mysql_pconnect("inforalv", "discoteca",
"password");
if (!$result)
return false;
if (!@mysql_select_db("discoteca"))
return false;
}
function getInstancia(){
if (!isset($this))
$_miInstancia=new db();
return $_miInstancia;
}
}
This is a Singleton Pattern, but it doesnt work.
I want to obtain only one instance of db class but when I do this...:
$conexiondb=db::getInstancia();
$conexiondb=db::getInstancia();
In the two calls I get a new db object.
Could you please tell me if there is anything wrong?
Thanks.
