What are the best practices for encoding URLs in PHP to avoid errors?

When encoding URLs in PHP, it is important to use the urlencode() function to properly encode special characters and avoid errors. This function ensures that the URL is correctly formatted and can be safely used in web requests. Additionally, it is recommended to use rawurlencode() for encoding the entire URL, including the scheme and host. 

$url = "https://www.example.com/?search=query with spaces";
$encodedUrl = urlencode($url);
echo $encodedUrl;
