What are common pitfalls when transferring PHP scripts to a new domain?

One common pitfall when transferring PHP scripts to a new domain is hardcoded URLs that are specific to the old domain. To solve this issue, you can use PHP's built-in functions like `str_replace` to dynamically replace the old domain with the new one in your script.

// Replace old domain with new domain in URLs
$old_domain = 'https://old-domain.com';
$new_domain = 'https://new-domain.com';
$content = file_get_contents('your_script.php');
$new_content = str_replace($old_domain, $new_domain, $content);
file_put_contents('your_script.php', $new_content);
