What are the necessary permissions and configurations required for successful file uploads in PHP?

To successfully upload files in PHP, you need to ensure that the directory where the files will be uploaded has the correct permissions set. Typically, the directory should have write permissions (e.g., 755 or 777). Additionally, you may need to adjust the PHP configuration settings related to file uploads, such as `upload_max_filesize`, `post_max_size`, and `max_file_uploads`. 

// Ensure the directory where files will be uploaded has the correct permissions
// For example, set the directory permissions to 755
chmod("upload_directory", 0755);

// Adjust PHP configuration settings for file uploads
ini_set('upload_max_filesize', '20M');
ini_set('post_max_size', '20M');
ini_set('max_file_uploads', '20');
