问题 How to get the UNIX timestamp range of the current hour, i mean one of the first second and the other for the last second. so if it's 18:45 i would get the timestamp of 18:00 and 18:59. Thanks 回答1: You can get the components of the current time with getdate() , and use mktime() to find the timestamps: $date = getdate(); $start = mktime($date['hours'], 0, 0); $end = $start + (60*60); You can also use date() , which is slightly simpler: $start = mktime(date("H"), 0, 0); $end = $start + (60*60);
