select from a function

[raduenea]

hy

 

I want to make a select in a class:

class test {

var $unu = array();

function __construct(){
	$link = mysql_connect("", "", "") or die("Couldn't make connection.");
	$db = mysql_select_db("", $link) or die("Couldn't select database");
	//$this->unu = $textin;	
}


function show($col){
	$q = mysql_query("SELECT $col FROM categorie");
	$qw = mysql_fetch_array($q);
	$this->unu = $qw;
	return $this->unu;
}

}

 

If I want to show how many rows are in that table:

$box = new test();

echo count($box->show("titlu"));

 

it show me that are only 2, although in "categorie" table are 10 rows.

 

Can you please tell me where is the error ?

Thanks
