How can PHP be used to pass data between pages using form submissions and SQL queries?

To pass data between pages using form submissions and SQL queries in PHP, you can collect the form data using POST method, process it in a PHP script, insert it into a database using SQL queries, and then retrieve the data on another page by querying the database. 

// Form submission page
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $data = $_POST['data'];
    
    // Insert data into database
    $sql = "INSERT INTO table_name (column_name) VALUES ('$data')";
    // Execute SQL query
}

// Data retrieval page
// Connect to database
$sql = "SELECT * FROM table_name";
// Execute SQL query
// Fetch data and display it on the page
