What are the potential security risks associated with passing sensitive data through URL parameters in PHP?

Passing sensitive data through URL parameters in PHP can expose the data to potential security risks such as interception, manipulation, and exposure in server logs. To mitigate these risks, sensitive data should be passed through POST requests instead of GET requests, as POST requests do not expose data in the URL. Additionally, sensitive data should be encrypted before transmission to ensure its security. 

<form method="post" action="process_data.php">
  <input type="hidden" name="sensitive_data" value="<?php echo encrypt($sensitive_data); ?>">
  <input type="submit" value="Submit">
</form>
