How to convert Unix timestamp (ie. 1286374738) to hhmmss?
答
date('His', $timestamp);
其中$ timestamp包含unix时间戳，H =带有零的小时的24小时格式，可以使用h = 12小时格式的一个小时与前导零; i =带前导零的分数，s =秒，前导零
where $timestamp contains the unix timestamp , H = 24-hour format of an hour with leading zeros , can use h = 12-hour format of an hour with leading zeros ; i = Minutes with leading zeros , s = Seconds, with leading zeros
