Fatal error: Call to undefined method mysqli_stmt::rowCount()

try {
$con = new mysqli($db_host, $db_username, $db_password,$db_name);

Assuming you want a real PDO solution, rather then a mysqli one:
try {
$aOptions = array( PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC);
// play around with options
$dbh = new PDO('mysql:host='.DBHOST.';dbname='.DBNAME.';charset=utf8', ''.DBUSER.'', ''.DBPWD.'',$aOptions);
}
catch(PDOException $e) {
echo $e->getMessage();
// do something smarter then just echo error!
}
$sql = "SELECT id, name, price FROM female_products ORDER BY name";
$stmt = $dbh->query($sql);
$aArray = $stmt->fetchAll();
if(count($aArray) > 0){
// do something
}
else{
// empty result
}
I personally think PDO is a much easier style then mysqli.
Options: you certainly gonna play with it soon, so it is handy to use an array for it.
You have used prepare,but yo do not make use of a prepared statement yet??
If this code works, try to find out hoe prepared statements work: one of the best defenses against SQL attacks!!
For configuration i used constants, so you need to define theme in your config. Constants, because they will never change during execution of your script!
