Initially I was using Andrew's function to convert a timestamp into a formatted age. It has
issues with times greater than a day (div by 0). I also added recursion to produce a result similar
to "2 decades 6 months 3 weeks 2 days 6 hours 56 minutes 52 seconds" when input a
timestamp from 1986. Hopefully someone will find this useful.
<?php
public static function TimeAgo($timestamp){
// Store the current time
$current_time = time();
// Determine the difference, between the time now and the timestamp
$difference = $current_time - $timestamp;
// Set the periods of time
$periods = array("second", "minute", "hour", "day",
"week", "month", "year", "decade");
// Set the number of seconds per period
$lengths = array(1, 60, 3600, 86400, 604800, 2630880, 31570560, 315705600);
// Determine which period we should use, based on the number of seconds lapsed.
// If the difference divided by the seconds is more than 1, we use that. Eg 1 year / 1 decade =
0.1, so we move on
// Go from decades backwards to seconds
for ($val = sizeof($lengths) - 1; ($val >= 0) && (($number = $difference /
$lengths[$val]) <= 1); $val--);
// Ensure the script has found a match
if ($val < 0) $val = 0;
// Determine the minor value, to recurse through
$new_time = $current_time - ($difference % $lengths[$val]);
// Set the current value to be floored
$number = floor($number);
// If required create a plural
if($number != 1) $periods[$val].= "s";
// Return text
$text = sprintf("%d %s ", $number, $periods[$val]);
// Ensure there is still something to recurse through, and we have not found 1 minute and 0
seconds.
if (($val >= 1) && (($current_time - $new_time) > 0)){
$text .= self::TimeAgo($new_time);
}
return $text;
}
