How can PHP developers effectively handle 403 Forbidden errors when trying to access external resources like CSS files for an editor integration?

When PHP developers encounter 403 Forbidden errors when trying to access external resources like CSS files for an editor integration, they can try setting user-agent headers to mimic a browser request. This can sometimes bypass the restriction set by the server. 

$url = 'https://example.com/style.css';
$user_agent = 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3';
$options = array(
    'http' => array(
        'header' => "User-Agent: $user_agent\r\n"
    )
);
$context = stream_context_create($options);
$css_content = file_get_contents($url, false, $context);
echo $css_content;
