What is the best way to hide query parameters in the URL and display only the main URL in PHP applications?

When passing sensitive information through query parameters in a URL, it is important to hide these parameters to prevent them from being easily visible to users. One way to achieve this is by using POST requests instead of GET requests to send data. By using POST requests, the parameters are not visible in the URL and are sent in the request body instead. 

<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    // Process the form data
    $username = $_POST['username'];
    $password = $_POST['password'];
    
    // Perform necessary actions with the data
}
?>

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