What is the importance of using $_POST instead of $_GET for form submissions in PHP?

Using $_POST instead of $_GET for form submissions in PHP is important because it helps to keep sensitive information, such as passwords, hidden from the URL. This helps to improve the security of the website and prevent unauthorized access to sensitive data. Additionally, using $_POST is a best practice for submitting data that will be processed and stored on the server side.

<form method="post" action="process_form.php">
    <input type="text" name="username">
    <input type="password" name="password">
    <button type="submit">Submit</button>
</form>
