((( Two Simultaneous Database Connections )))

[MacroPhotoPro]

I am trying to access two databases on the same php page - one that I created, and the other being the vBulletin database.

// On Server Development
$host = 'localhost';
$user = 'user";
$pass = 'passwerd';

// Define the databases
$user_database = 'forum';
$cust_database = 'custom_database';

// Establish the connections
$user_con = mysql_connect($host,$user,$pass) or die(mysql_error());
$cust_con = mysql_connect($host,$user,$pass) or die(mysql_error());

// Connect to the databases
mysql_select_db($user_database, $user_con);
mysql_select_db($cust_database, $cust_con);

// Close the connections
mysql_close($user_con);
mysql_close($cust_con);

// Demonstrate that the connections didn't throw an exception
phpinfo();


It's not working and there seems to be some mechanism preventing it from working.

Why can I not have two simultaneous connections? Is there some prohibition against having two simultaneous database connections with MYSQL? If you require additional information, please let me know.

Thank you,

Jack

MySQL returns the same connection ID if you connect to two databases at once. So if you do need to connect to two databases, you need to do so before each query.

In your case, $user_con will be the same as the $cust_con connection ID.

You can also avoid this by passing the 4th connect parameter to the second connection like this...

$cust_con = mysql_connect($host,$user,$pass,true) or die(mysql_error());
