What potential issues can arise when running the same PHP application on different servers?

One potential issue that can arise when running the same PHP application on different servers is differences in server configurations. This can lead to compatibility issues with the application, resulting in errors or unexpected behavior. To solve this problem, you can use a configuration file that contains server-specific settings and adjust them accordingly for each server. 

// config.php
$server = $_SERVER['SERVER_NAME'];

if ($server === 'server1') {
    // Server 1 specific configurations
    $db_host = 'localhost';
    $db_user = 'user1';
    $db_pass = 'password1';
} elseif ($server === 'server2') {
    // Server 2 specific configurations
    $db_host = 'remotehost';
    $db_user = 'user2';
    $db_pass = 'password2';
}

// Use $db_host, $db_user, $db_pass in your application
