What are some best practices for passing values in PHP using bookmarks?

When passing values in PHP using bookmarks, it is best practice to encode the values to prevent any special characters or spaces from causing issues. This can be achieved by using the urlencode() function to encode the values before appending them to the URL. When retrieving the values, you can use the urldecode() function to decode them back to their original form. 

// Encoding the value before appending it to the URL
$value = 'example value';
$encoded_value = urlencode($value);
$url = "example.php?value=$encoded_value";

// Decoding the value when retrieving it from the URL
$decoded_value = urldecode($_GET['value']);
echo $decoded_value;
