How can form data be passed between different steps of an installation process in PHP?

When passing form data between different steps of an installation process in PHP, you can use sessions to store and retrieve the form data. By storing the form data in session variables, you can access it across different pages during the installation process. 

<?php
session_start();

// Check if form data has been submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Store form data in session variables
    $_SESSION['step1_data'] = $_POST['step1_data'];
    $_SESSION['step2_data'] = $_POST['step2_data'];
    
    // Redirect to the next step of the installation process
    header("Location: step2.php");
    exit();
}

// Retrieve form data from session variables
$step1_data = isset($_SESSION['step1_data']) ? $_SESSION['step1_data'] : '';
$step2_data = isset($_SESSION['step2_data']) ? $_SESSION['step2_data'] : '';
?>
