What is the purpose of specifying the action attribute in a form element in PHP?

Specifying the action attribute in a form element in PHP is important because it tells the form where to send the data once it is submitted. This attribute specifies the URL of the script that will process the form data. Without specifying the action attribute, the form data will not be sent anywhere and the form will not be functional.

<form action="process_form.php" method="post">
  <!-- form fields go here -->
  <input type="submit" value="Submit">
</form>
