Re: var static

I've found the solution myself. The db class is the next: class db{ function db (){ // funcion que se conecta con la BBDD $result = @mysql_pconnect("inforalv", "discoteca", "password"); if (!$result) return false; if (!@mysql_select_db("discoteca")) return false; } function &getInstancia(){ static $miInstancia; if (!get_class($miInstancia) == 'db') $miInstancia=new db(); return $miInstancia; } and the call to this class is the next: $conexiondb1=&db::getInstancia(); $conexiondb2=&db::getInstancia(); In the second call I obtain the same object.

Although PHP supports static variables in functions (see here), it has no support for static variables in classes. http://www.php.net/manual/en/language.variables.scope.php (espero que te sirva) saludos aniceto lópez :: DYNAMICAL.BIZ web development & host services Barcelona - Spain -----Mensaje original----- Asunto: [PHP] var static I want to obtain only one instance of one class. In other to do that, I call to a static method, that creates the instance(if it doesnt exit) or returns the reference of the instance. The call to the static method is the next: $conexiondb=db::getInstancia(); Well, but if I call to db::getInstancia() another time, I obtain another new object :-( The code of the db class is the next (it is a Singleton Pattern, but it doesnt work) 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; } } I think that the problem is that the var _miInstance is not static and I dont know how to do it. Could you please tell me if there is anything wrong? Thanks. Alvaro -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
