What is the potential issue with passing values containing spaces in a dynamic form with PHP?

When passing values containing spaces in a dynamic form with PHP, the values may get truncated or split at the spaces when submitted. To solve this issue, you can use URL encoding to encode the values before passing them in the form, and then decode them after submission to retrieve the original values. 

// Encoding the value containing spaces before passing it in the form
$value_with_spaces = "Hello World";
$encoded_value = urlencode($value_with_spaces);

// In the form
<input type="text" name="my_field" value="<?php echo $encoded_value; ?>">

// Decoding the value after form submission
$decoded_value = urldecode($_POST['my_field']);
