</select>
and in the PHP part :
在 PHP 部分：
$cars = $_POST['cars'];
print_r ($cars);
回答by Alaa M. Jaddou
you must do the following:
您必须执行以下操作：
//$_POST or $_GET is the method of your form request
//$_POST 或 $_GET 是你的表单请求的方法
foreach ($_POST['cars'] as $selected_option) {
echo $selected_option;
}
that's it.
就是这样。
