What is the recommended method to pass variables between PHP pages using POST method?

When passing variables between PHP pages using the POST method, it is recommended to use the $_POST superglobal array to retrieve the values sent from the previous page. This array contains key-value pairs of the form data sent via POST method. To pass variables between PHP pages, you can set the form action attribute to the target PHP page and use the $_POST array to access the values. 

// Source PHP page
<form method="post" action="target_page.php">
    <input type="text" name="username">
    <input type="submit" value="Submit">
</form>

// Target PHP page (target_page.php)
<?php
if(isset($_POST['username'])){
    $username = $_POST['username'];
    echo "Hello, " . $username;
}
?>
