What are some best practices for ensuring the smooth operation of PHP scripts when moving a website to a new hosting provider?

When moving a website to a new hosting provider, it is important to ensure that PHP scripts run smoothly to prevent any issues with the website's functionality. One best practice is to update the file paths in the PHP scripts to reflect the new server environment. This can include updating the paths for includes, requires, and file uploads to ensure that the scripts can access the necessary files and directories.

// Update file paths in PHP scripts for new hosting provider
$old_path = '/old/path/to/file.php';
$new_path = '/new/path/to/file.php';

include_once str_replace($old_path, $new_path, $old_path);
