What are the potential consequences of using the wrong method attribute in a PHP form?

Using the wrong method attribute in a PHP form can lead to errors or unexpected behavior when submitting the form. To solve this issue, ensure that the method attribute matches the HTTP method you want to use for form submission (either "GET" or "POST"). 

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