我是这样的意思

改写为

然后我页面调用的时候 直接 就可以了
取回的是数组 你这种需求反人类...难道你要在function里把格式都写好,那也是反人类设计.
所以 我觉得你还是按照你原来的额写法写算了，别搞function了....
function你能看懂 剩下的不就是循环出数据 拼接成你要的样子吗？这个地方也不熟悉的话 我建议你先弄清楚返回的数据结构...
不知道怎么说了
查找别的问题 偶然解决了这个， 回来做个标记 顺便吧解决方法贴上来留着
function index($title,$limit){$text="select * from test wheretag like '%$title%' order by test.id desc limit $limit"; return $text;}echo index('条件','可以多个');
