有这样一个函数,递归调用的,同时里面又有循环,可是递归之后,应该是由于$v被重新赋值的原因吧,循环就不再进行了。麻烦问高手们怎么解决?
------解决方案--------------------
试试加一句 reset($reply_arr)在循环前,
另外你那个$layer又在参数里(但是调用没用到),又global了,好像有点不妥
------解决方案--------------------
你把 show_child($v['pid']); 拿到if外面试试
------解决方案--------------------
你的意思是在第五层停止继续进行递归是不是?
如果是的话可以这么实现。
如果是我理解错了,就当我没有来过这里。
