你能以你想要的形式添加json示例输出吗？我无法从你的问题中理解。检查你正在插入元素的循环，以你不想要的方式。你的结构有点复杂。尝试在
$arr['submenu']=array（）之后添加if（$count1>0）
。可能您只是忘记了在下一个循环之前截断子菜单数组。@ihsan我把我想要的东西放到了json输出中，是的，它非常有用complicated@Narekthx为您提供信息，我尝试了您的指令，但它不好工作不工作我尝试了您的指令$arr=[]；您好@ihsan thx为您提供评论和线索“在下一个循环之前先重置数组”，我尝试使用$arr=array（）；并且工作得很好hihi，，thx all master:）@arolehaqi关于$arr=[]；一些编辑器称这是一个错误，但是我没有看到php反对它。你很好。
