What could be the reason for the change in behavior of the script when switching web hosting providers?

The change in behavior of the script when switching web hosting providers could be due to differences in server configurations, PHP versions, or installed extensions. To solve this issue, you should review the error logs to identify any specific errors or warnings that are causing the script to behave differently. Additionally, make sure that the PHP code is compatible with the new hosting environment and update any deprecated functions or syntax.

// Example of checking for errors in PHP code
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Your PHP code here
// Make sure to update any deprecated functions or syntax
