How old I am
I just happen to know I was born at 1:25pm on my birthday. This solution works, but a little funny. I'm specifying that there are 365.251 days in a year because my 6th grade math teacher taught me so (every hundred years an additional leap day occurs and February has 30 days.

<?
        $bday = mktime(13,25,0,7,25,1979);

        $calc = time()-$bday;

        $years = floor($calc/60/60/24/365.251);
        $cdr = (($calc/60/60/24/365.251)-floor($calc/60/60/24/365.251));
        $months = floor(12*$cdr);
        $cdr = (12*$cdr)-floor(12*$cdr);
        $days = floor(30.5*$cdr);
        $cdr = (30.5*$cdr)-floor(30.5*$cdr);  // cheap math, averaging 31 days to 30.5
        $hours = floor(24*$cdr);
        $cdr = (24*$cdr)-floor(24*$cdr);
        $mins = floor(60*$cdr);
        $cdr = (60*$cdr)-floor(60*$cdr);
        $secs = floor(60*$cdr);
       
        echo "I am ".$years." years, ".$months." months, ".$days." days, ".$hours." hours, ".$mins.", minutes, ".$secs." seconds old... and completely fascinated by life.";
?>


Ok, so the code above is fairly ugly. The following is something I found in at php.net by jason at thinking man. Its lengthy, but concise.

<?php
define('INT_SECOND', 1);
define('INT_MINUTE', 60);
define('INT_HOUR', 3600);
define('INT_DAY', 86400);
define('INT_WEEK', 604800);

function get_formatted_timediff($then, $now = false)
{
    $now      = (!$now) ? time() : $now;
    $timediff = ($now - $then);
    $weeks    = (int) intval($timediff / INT_WEEK);
    $timediff = (int) intval($timediff - (INT_WEEK * $weeks));
    $days     = (int) intval($timediff / INT_DAY);
    $timediff = (int) intval($timediff - (INT_DAY * $days));
    $hours    = (int) intval($timediff / INT_HOUR);
    $timediff = (int) intval($timediff - (INT_HOUR * $hours));
    $mins     = (int) intval($timediff / INT_MINUTE);
    $timediff = (int) intval($timediff - (INT_MINUTE * $mins));
    $sec      = (int) intval($timediff / INT_SECOND);
    $timediff = (int) intval($timediff - ($sec * INT_SECOND));

    $str = '';
    if ( $weeks )
    {
        $str .= intval($weeks);
        $str .= ($weeks > 1) ? ' weeks' : ' week';
    }

    if ( $days )
    {
        $str .= ($str) ? ', ' : '';
        $str .= intval($days);
        $str .= ($days > 1) ? ' days' : ' day';
    }

    if ( $hours )
    {
        $str .= ($str) ? ', ' : '';
        $str .= intval($hours);
        $str .= ($hours > 1) ? ' hours' : ' hour';
    }

    if ( $mins )
    {
        $str .= ($str) ? ', ' : '';
        $str .= intval($mins);
        $str .= ($mins > 1) ? ' minutes' : ' minute';
    }

    if ( $sec )
    {
        $str .= ($str) ? ', ' : '';
        $str .= intval($sec);
        $str .= ($sec > 1) ? ' seconds' : ' second';
    }
   
    if ( !$weeks && !$days && !$hours && !$mins && !$sec )
    {
        $str .= '0 seconds ago';
    }
    else
    {
        $str .= ' ago';
    }
   
    return $str;
}
?>
