For your troubles (source) - the internet is awesome:
/* takes an argument in unix time (seconds) */ function time_since($original) { // array of time period chunks $chunks = array( array(60 * 60 * 24 * 365 , 'year'), array(60 * 60 * 24 * 30 , 'month'), array(60 * 60 * 24 * 7, 'week'), array(60 * 60 * 24 , 'day'), array(60 * 60 , 'hour'), array(60 , 'minute'), ); $today = time(); /* Current unix time */ $since = $today - $original; // $j saves performing the count function each time around the loop for ($i = 0, $j = count($chunks); $i < $j; $i++) { $seconds = $chunks[$i][0]; $name = $chunks[$i][1]; // finding the biggest chunk (if the chunk fits, break) if (($count = floor($since / $seconds)) != 0) { // DEBUG print "<!-- It's $name --> "; break; } } $print = ($count == 1) ? '1 '.$name : "$count {$name}s"; if ($i + 1 < $j) { // now getting the second item $seconds2 = $chunks[$i + 1][0]; $name2 = $chunks[$i + 1][1]; // add second item if it's greater than 0 if (($count2 = floor(($since - ($seconds * $count)) / $seconds2)) != 0) { $print .= ($count2 == 1) ? ', 1 '.$name2 : ", $count2 {$name2}s"; } } return $print; } echo time_since(strtotime('2011-05-13 12:22:11')); // 1 day, 2 hours
