What is the correct way to pass values from a homepage to a PHP program and display them back on the homepage?

To pass values from a homepage to a PHP program and display them back on the homepage, you can use a form on the homepage to collect user input and submit it to a PHP script using POST method. In the PHP script, you can retrieve the values using $_POST superglobal, process them, and then display the processed values back on the homepage. 

// Homepage (index.php)
<form method="post" action="process.php">
    <input type="text" name="name" placeholder="Enter your name">
    <input type="submit" value="Submit">
</form>

// process.php
<?php
if(isset($_POST['name'])){
    $name = $_POST['name'];
    echo "Hello, " . $name . "!"; // Display the processed value back on the homepage
}
?>
