What are the potential challenges of accessing a DB2 database from a PHP application running on a remote server?

One potential challenge of accessing a DB2 database from a PHP application running on a remote server is ensuring that the necessary drivers are installed and configured correctly on the remote server. Additionally, network latency can impact the performance of the database queries. To address these challenges, make sure to install the appropriate DB2 drivers on the remote server and optimize the database queries to minimize network latency. 

// Example code to connect to a DB2 database from a PHP application on a remote server

$db = db2_connect('DATABASE=sample;HOSTNAME=remote_server_ip;PORT=50000;PROTOCOL=TCPIP;UID=username;PWD=password', 'username', 'password');

if ($db) {
    echo "Connected to the DB2 database.";
} else {
    echo "Failed to connect to the DB2 database.";
}
