Answer 1

Hi Please try code given below,

$link = @mysql_connect("Ip Addres to another website","username for mysql 2","passowrd 2 ")or die("Couldn't make connection.") or die(mysql_error());

mysql_select_db("qatarlab_test",$link)or die("Couldn't select database", $link) or die(mysql_error());

$factorRes = @mysql_query("SELECT count(id) FROM `factor` " , $link) or die(mysql_error());

$factorRow = @mysql_fetch_array($factorRes);        

echo "<pre>";
print_r($factorRow);
echo "</pre>";

Here $link will be for specific database connection and die(mysql_error()) for if any error in or query or database connection.

thanks

In your first line: mysql_connect you are passing the IP Address and Username for connecting the DB.

Make sure that the user has the privilege to connect to the DB remotely (ie via a machine other than the Localhost). In general, when a user is added in the DB its default access is for the localhost. Check out this link: http://dev.mysql.com/doc/refman/5.1/en/adding-users.html

You basically need to add user using: CREATE USER 'admin'@'IP Address of Website 1'; All the CPanel's have this provision in their interface as well.

Firstly, you must enable remote database connection in the original site so that the new site can connect to it. you can do this in the control panel->Database(Remote Database Connection) of the original site.

You could specify the IP or domain of the new site to that it allows only the new site to connect or you could just add wildcard (%) to allow any external connection to the database.

when this is done, run ur query again.

hope it helps
