note 76736 deleted from function.time by aidan

Note Submitter: Sean Sullivan ---- Fixed divide by zero warnings given by the timeDiff function. The change is that the for loop doesn't count down to 0 anymore, just 1. I dont think it has any side effects. <?php # max_detail_levels - how deep to go down? If max_detail_levels is set to 2, text will output something like "3 days 4 hours" instead of "3 days 4 hours 10 minutes 55 seconds" # precision_level - this is what rspenc29 was trying to accomplish. If you want to only report a minimum value of say 1 hour, then you should set this to "hour" function timeDiff($timestamp,$detailed=false, $max_detail_levels=8, $precision_level='second'){ $now = time(); #If the difference is positive "ago" - negative "away" ($timestamp >= $now) ? $action = 'away' : $action = 'ago'; # Set the periods of time $periods = array("second", "minute", "hour", "day", "week", "month", "year", "decade"); $lengths = array(1, 60, 3600, 86400, 604800, 2630880, 31570560, 315705600); $diff = ($action == 'away' ? $timestamp - $now : $now - $timestamp); $prec_key = array_search($precision_level,$periods); # round diff to the precision_level $diff = round(($diff/$lengths[$prec_key]))*$lengths[$prec_key]; # if the diff is very small, display for ex "just seconds ago" if ($diff <= 10) { $periodago = max(0,$prec_key-1); $agotxt = $periods[$periodago].'s'; return "just $agotxt $action"; } # Go from decades backwards to seconds $time = ""; for ($i = (sizeof($lengths) - 1); $i>0; $i--) { if($diff > $lengths[$i-1] && ($max_detail_levels > 0)) { # if the difference is greater than the length we are checking... continue $val = floor($diff / $lengths[$i-1]); # 65 / 60 = 1. That means one minute. 130 / 60 = 2. Two minutes.. etc $time .= $val ." ". $periods[$i-1].($val > 1 ? 's ' : ' '); # The value, then the name associated, then add 's' if plural $diff -= ($val * $lengths[$i-1]); # subtract the values we just used from the overall diff so we can find the rest of the information if(!$detailed) { $i = 0; } # if detailed is turn off (default) only show the first set found, else show all information $max_detail_levels--; } } # Basic error checking. if($time == "") { return "Error-- Unable to calculate time."; } else { return $time.$action; } } ?> [EDIT by danbrown AT php DOT net: Modifications from the original below up to this version were deleted from the user notes.
