Smarty中的iteration,index学习备忘
.iteration
iteration contains the current loop iteration and always starts at one, unlike index. It is incremented by one on each iteration.
iteration包含当前循环次数，与index不同，从1开始，每次循环增长1。
.index
index contains the current array index, starting with zero.
.index包含当前数组索引，从零开始。
每行显示5条数据
