This is what i have done so far
    function save_menu()
    {
        $menu = $_POST['menu'];
        foreach($menu as $key => $item) 
        {
            $sql = "INSERT INTO tbl_menu (`title`,`parent`) values ('".$item['title']."','')";  
            mysql_query($sql);
        }
    }

Answer 1

function save_menu()
{
    $menu = $_POST['menu'];

        svae_data($menu)  
}

public function save_data($menu)
{

      foreach($menu as $key => $item) 
      {
           $sql = "INSERT INTO tbl_menu (`title`,`parent`) values  ('".$item['title']."','')";  
           mysql_query($sql);

           if(isset($item['childs']))
           {
                save_data($item['childs'])
           }
     }

}

Answer 2

这是您想要的代码，但是请注意注入，并且自PHP 5.5以来mysql_函数已被弃用，因此使用PDO或mysqli。链接中的更多信息，请参见下文。

PHP PDO

mysql_real_escape_string

How can I prevent SQL injection in PHP?

function save_menu_recursive($menu, $parent = null) {
    if (!$parent) {
        $sql = "INSERT INTO tbl_menu(`title`) VALUES('{$menu->title}')";
    }
    else {
        $sql = "INSERT INTO tbl_menu(`title`, `parent`) VALUES('{$menu->title}', {$parent})";
    }
    mysql_query($sql);
    if (isset($menu->childs) && is_array($menu->childs)) {
        $insertedId = mysql_insert_id();
        foreach($menus->childs as $child) {
            save_menu_recursive($child, $insertedId);
        }
    }
}
