Here is something I found (and changed) that outputs the difference, something like "272 days 17 hours 33 mins". Hope ya'll can use it! [code] <?php $current_date = date("Y-m-d"); $current_time = date("h:i:s"); $user_date = "2006-12-1"; $user_time = "1:00:00"; function unix_diff($first_date,$first_time,$second_date,$second_time) { // Author: Tone. // edited by Davidude // Date : 15-12-2003. // Ref: Dates go in "2003-12-31". // Ref: Times go in "12:59:13". // Ref: mktime(HOUR,MIN,SEC,MONTH,DAY,YEAR). // Splits the dates into parts, to be reformatted for mktime. $first_date_ex = explode("-",$first_date); $first_time_ex = explode(":",$first_time); $second_date_ex = explode("-",$second_date); $second_time_ex = explode(":",$second_time); // makes the dates and times into unix timestamps. $first_unix = mktime($first_time_ex[0], $first_time_ex[1], $first_time_ex[2], $first_date_ex[1], $first_date_ex[2], $first_date_ex[0]); $second_unix = mktime($second_time_ex[0], $second_time_ex[1], $second_time_ex[2], $second_date_ex[1], $second_date_ex[2], $second_date_ex[0]); // Gets the difference between the two unix timestamps. $timediff = $first_unix-$second_unix; // Works out the days, hours, mins and secs. $days=intval($timediff/86400); $remain=$timediff%86400; $hours=intval($remain/3600); $remain=$remain%3600; $mins=intval($remain/60); $secs=$remain%60; // Returns a pre-formatted string. Can be chagned to an array. return $days . " days " . $hours . " hours " . $mins . " mins"; } $diff = unix_diff($current_date,$current_time,$user_date,$user_time); $diff = str_replace("-", "", $diff); echo $diff; ?>[/code]
