Are there any best practices for linking multiple forms within a PHP document?

When linking multiple forms within a PHP document, it is best practice to use unique form IDs and action attributes to differentiate between the forms and ensure they are submitted to the correct processing script. Additionally, using POST method for form submissions is recommended for better security and to prevent sensitive data from being displayed in the URL.

<form id="form1" action="process_form1.php" method="post">
  <!-- Form 1 fields here -->
</form>

<form id="form2" action="process_form2.php" method="post">
  <!-- Form 2 fields here -->
</form>
