php中foreach循环里面做if判断

大概就是两种数组，一种是JSON串，一种就是纯数字的。问题是现在页面foreach循环的时候判断这个长度没有用呢。

解决了，直接在返回的数组里面加了一个数组长度，页面取值的时候eq一下就好了。

判断里面是 <foreach name="zhuye" item="zhuye_item" key="zhuye_key"> <div>头像： <if condition='mb_strlen(zhuye_item.note5uuidHeadIdx) gt 10'>{$zhuye_item.smallUrl}<else/>{$zhuye_item.note5uuidHeadIdx}</if> 用户： {$zhuye_item.note5uuidAnonym} <eq name="zhuye_item.type" value="0"> 评论： {$zhuye_item.content}</eq><eq name="zhuye_item.type" value="1"> 打分：{$zhuye_item.content}</eq></div> </foreach> 循环里头像这块判断不成功
