How can the correct URL protocol (http:// instead of ftp://) impact the functionality of PHP scripts and HTML forms when submitting data to a MySQL database?

When submitting data to a MySQL database, using the correct URL protocol (http:// instead of ftp://) is crucial for ensuring that the data is transmitted securely and accurately. Failure to use the correct protocol can result in errors or data loss when submitting data through PHP scripts and HTML forms. To fix this issue, always ensure that the URL protocol is specified correctly in the form action attribute or the PHP script that handles the form submission.

<form action="http://example.com/process_form.php" method="post">
  <!-- form fields go here -->
</form>
