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.

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);

回答2:

$start = mktime(date('H'), 0, 0);
$end = mktime(date('H'), 59, 59);

Could be generalized for any timestamp, not just the current time, as:

$time = time(); // some timestamp
$start = mktime(date('H', $time), 0, 0, date('n', $time), date('j', $time), date('Y', $time));
$end = mktime(date('H', $time), 59, 59, date('n', $time), date('j', $time), date('Y', $time));
