How can PHP developers efficiently handle form data from multiple forms on a webpage without using $_SESSION or $_GET?

When handling form data from multiple forms on a webpage without using $_SESSION or $_GET, PHP developers can utilize the $_POST superglobal array to access the form data submitted via POST method. By setting unique names for form elements within each form, developers can differentiate between the data submitted from different forms. Using conditional statements based on the form names or IDs can help in processing the form data efficiently.

if ($_SERVER["REQUEST_METHOD"] == "POST") {
    if(isset($_POST['form1_submit'])) {
        // Process form data from form 1
        $form1_data = $_POST['form1_data'];
    } elseif(isset($_POST['form2_submit'])) {
        // Process form data from form 2
        $form2_data = $_POST['form2_data'];
    }
}
