Use PDO instead

[swordwoman]

Original File
mysql_connect(“localhost”,“root”,"") or die(“Cannot connect to server”);
mysql_select_db(“data”) or die(“Cannot select Database”);

Edit
mysql_connect(“databases.000webhost.com”,“root”,“123456”) or die(“Cannot connect to server”);
mysql_select_db(“id3399948_data”) or die(“Cannot select Database”);

You can’t use root
