[SOLVED] how to subtract dates to get age?

[ted_chou12]

if my birthday is 2005-6-19, how do I get my age?
I tried strtotime() and subtract the birthdate from the current date , but it doesnt work... i get a negative big number.
Can anyone help me with this? thanks

The difference is in seconds. You'll have to do the math to figure out how many years, months, weeks, days, hours, seconds.

nope does work... that number is too small for my age as well.

here's an approximation. The months is not going to be 100%. Someone has something better somewhere, you might have to dig.

[code]<?php
$date="12 March 1983";
$total=time()-strtotime($date);
$calc=array('years'=>60*60*24*365, 'months'=>60*60*24*30,'days'=>60*60*24,'hours'=>60*60,'minutes'=>60);
do {
if(current($calc)<$total) {
echo floor($total/current($calc))." ".key($calc)."<br />\n";
$total=$total - floor($total/current($calc))*current($calc);
}
}while(next($calc));

?>[/code]
