What are the potential issues with using the GET method in PHP form submissions?

When using the GET method in PHP form submissions, sensitive data such as passwords or personal information is exposed in the URL, which can be easily accessed and viewed by anyone. To solve this issue, it is recommended to use the POST method instead, which sends form data in the HTTP request body rather than in the URL.

<form method="post" action="submit.php">
    <!-- Form fields go here -->
</form>
