How can PHP beginners ensure proper form handling when using buttons within a foreach loop?

When using buttons within a foreach loop in PHP, beginners should ensure that each button has a unique name or identifier to handle form submissions correctly. One way to achieve this is by appending the loop index or a unique identifier to the button name. This allows the PHP script to differentiate between different button submissions and process them accordingly.

<?php
$items = ['Item 1', 'Item 2', 'Item 3'];

if ($_SERVER["REQUEST_METHOD"] == "POST") {
    foreach ($items as $key => $item) {
        if (isset($_POST['submit_' . $key])) {
            // Handle form submission for the specific button
            echo "Button $key clicked!";
        }
    }
}

foreach ($items as $key => $item) {
    echo "<form method='post'>";
    echo "<label>$item</label>";
    echo "<input type='submit' name='submit_$key' value='Submit'>";
    echo "</form>";
}
?>
