What are common pitfalls when changing upload paths in PHP scripts?

Common pitfalls when changing upload paths in PHP scripts include incorrect file permissions, not updating the file paths in the script, and potential security vulnerabilities if the new path is not properly secured. To solve this, make sure the new upload path has the correct permissions, update all instances of the old path in the script, and use proper sanitization and validation techniques to secure the new path. 

// Set the new upload path
$new_upload_path = '/path/to/new/upload/directory/';

// Update the upload path in the script
$_FILES['file']['tmp_name'] = $new_upload_path . $_FILES['file']['name'];

// Ensure the new upload path is secure
if (strpos($_FILES['file']['tmp_name'], $new_upload_path) !== 0) {
    die('Invalid upload path');
}
