Connecting to database everytime You make an instance

Hello dear colleagues from the TalkPHP forum,

I am trying to build a class to read the content of all my tables.
I am calling this class record.

Everytime I create an instance of this class I am sending all the database information on the "new" sentence, meaning:

PHP Code:


			

$customer = new record("$hostname", "$user_db", "$pass_db", "$database","$record_to_pick","$table_name");

Inside the class I am performing everytime all the normal operations of accessing a database, meaning:

PHP Code:


			

public function __construct($host,$username,$password,$db,$recordtopick,$tablename)
{
$this->host         = $host;
$this->username     = $username;
$this->password     = $password;
$this->db           = $db;
$this->recordtopick = $recordtopick;
$this->$tablename   = $tablename;
$this->conectar();
} 

private function conectar()
{
$this->link = mysql_connect($this->host, $this->username, $this->password);
mysql_select_db($this->db, $this->link);
}

Most of the times, even in a very small program I am using this class many times to read several tables.

My questions are:
1) Is the fact of using this class so often, therefore connecting to the database so many times, making my programs slow down?
2) If so, how can I improve my programs?

Thanks in advance for all replies,
PP
