note 99393 added to function.time

This is another function to calculate the difference between two times and output it in a relative format. This one, however, combines various units. In other words, it will return "3 days, 2 hours, 6 minutes, and 2 seconds ago" instead of "3 days ago." Please bear in mind that it is intended for times that are very close together. It will not be accurate for calculating dates more than a month apart. This is because one of the units it relies on is "weeks," which do not correspond directly with months. What I'm trying to get across is, the program assumes that a month is precisely 4 weeks long, i.e. 28 days. This also means that a "year" according to this function is 336 days. <?php function rel_time($from, $to = null) { $to = (($to === null) ? (time()) : ($to)); $to = ((is_int($to)) ? ($to) : (strtotime($to))); $from = ((is_int($from)) ? ($from) : (strtotime($from))); $units = array ( "year" => 29030400, // seconds in a year (12 months) "month" => 2419200, // seconds in a month (4 weeks) "week" => 604800, // seconds in a week (7 days) "day" => 86400, // seconds in a day (24 hours) "hour" => 3600, // seconds in an hour (60 minutes) "minute" => 60, // seconds in a minute (60 seconds) "second" => 1 // 1 second ); $diff = abs($from - $to); $suffix = (($from > $to) ? ("from now") : ("ago")); foreach($units as $unit => $mult) if($diff >= $mult) { $and = (($mult != 1) ? ("") : ("and ")); $output .= ", ".$and.intval($diff / $mult)." ".$unit.((intval($diff / $mult) == 1) ? ("") : ("s")); $diff -= intval($diff / $mult) * $mult; } $output .= " ".$suffix; $output = substr($output, strlen(", ")); return $output; } ?> The function rel_time() accepts two parameters: $from and $to. For best results, provide them as UNIX timestamps (derived from PHP's time() function). They also accept formats supported by strtotime(). $to is an optional argument and defaults to the current time. The function will calculate the difference between $from and $to. If $from occurs after $to, the function will substitue "ago" with "from now." Example usage: <?php echo rel_time("September 2, 2010 4:20 PM"); // returns "2 weeks, 4 days, 23 hours, 25 minutes, and 3 seconds from now" ?> ---- Server IP: 69.147.83.197 Probable Submitter: 72.208.240.199 ---- Manual Page -- http://www.php.net/manual/en/function.time.php Edit -- https://master.php.net/note/edit/99393 Del: integrated -- https://master.php.net/note/delete/99393/integrated Del: useless -- https://master.php.net/note/delete/99393/useless Del: bad code -- https://master.php.net/note/delete/99393/bad+code Del: spam -- https://master.php.net/note/delete/99393/spam Del: non-english -- https://master.php.net/note/delete/99393/non-english Del: in docs -- https://master.php.net/note/delete/99393/in+docs Del: other reasons-- https://master.php.net/note/delete/99393 Reject -- https://master.php.net/note/reject/99393 Search -- https://master.php.net/manage/user-notes.php
