是否有任何函数以相反的顺序对数组进行排序？

Question

Is there any php function built in to make it easy to take a database of information and reverse the order in which it echo's while fetching it from a PHP script?

For instance a comment system, it would make it a lot easier if there was a function to reverse the order of the echo's to make the newest comment on the top.

Answer 1

yes...instead of echoing it out as you fetch row, you can first put the rows in an array and use rsort or arsort and then loop through and echo..or..you can do it in the mysql query (ideal) by adding ...order by columnname desc to your query
