What are the best practices for naming form elements, specifically the submit button, in PHP?

When naming form elements in PHP, it is important to use descriptive and meaningful names to ensure clarity and maintainability of the code. For the submit button specifically, it is recommended to use a name that reflects its purpose, such as "submit" or "submitBtn". This will make it easier to identify and handle the button in the PHP code.

<form method="post" action="process_form.php">
  <!-- Other form elements -->
  <input type="submit" name="submit" value="Submit Form">
</form>
