<?php
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    echo '<script>';
    echo 'var result = confirm("Are you sure you want to delete this item?");';
    echo 'if (result) {';
    echo '  // Code to delete the item';
    echo '} else {';
    echo '  // Code if user cancels delete operation';
    echo '}';
    echo '</script>';
}
?>
