Ok my dear
here is a php script for displaying actual date of birth of user.

Code:

<div class="fields">
[COLOR=#000000][COLOR=#0000BB]<?php
    $year_diff [/COLOR][COLOR=#007700]= [/COLOR][COLOR=#0000BB]date[/COLOR][COLOR=#007700]([/COLOR][COLOR=#DD0000]"Y"[/COLOR][COLOR=#007700]) - ([/COLOR][COLOR=#0000BB]$user[/COLOR][COLOR=#007700]->[/COLOR][COLOR=#0000BB]profile_dob[/COLOR][COLOR=#007700]{[/COLOR][COLOR=#0000BB]year[/COLOR][COLOR=#007700]});
    [/COLOR][COLOR=#0000BB]$month_diff [/COLOR][COLOR=#007700]= [/COLOR][COLOR=#0000BB]date[/COLOR][COLOR=#007700]([/COLOR][COLOR=#DD0000]"m"[/COLOR][COLOR=#007700]) - ([/COLOR][COLOR=#0000BB]$user[/COLOR][COLOR=#007700]->[/COLOR][COLOR=#0000BB]profile_dob[/COLOR][COLOR=#007700]{[/COLOR][COLOR=#0000BB]month[/COLOR][COLOR=#007700]});
    [/COLOR][COLOR=#0000BB]$day_diff [/COLOR][COLOR=#007700]= [/COLOR][COLOR=#0000BB]date[/COLOR][COLOR=#007700]([/COLOR][COLOR=#DD0000]"d"[/COLOR][COLOR=#007700]) - ([/COLOR][COLOR=#0000BB]$user[/COLOR][COLOR=#007700]->[/COLOR][COLOR=#0000BB]profile_dob[/COLOR][COLOR=#007700]{[/COLOR][COLOR=#0000BB]day[/COLOR][COLOR=#007700]});
    if ([/COLOR][COLOR=#0000BB]$month_diff [/COLOR][COLOR=#007700]< [/COLOR][COLOR=#0000BB]0[/COLOR][COLOR=#007700])
      [/COLOR][COLOR=#0000BB]$year_diff[/COLOR][COLOR=#007700]--;
    elseif ([/COLOR][COLOR=#0000BB]$month_diff [/COLOR][COLOR=#007700]== [/COLOR][COLOR=#0000BB]0 [/COLOR][COLOR=#007700]&& [/COLOR][COLOR=#0000BB]$day_diff [/COLOR][COLOR=#007700]< [/COLOR][COLOR=#0000BB]0[/COLOR][COLOR=#007700])
      [/COLOR][COLOR=#0000BB]$year_diff[/COLOR][COLOR=#007700]--;
[/COLOR][COLOR=#0000BB]?>[/COLOR][/COLOR]
<p>AGE: [COLOR=#000000][COLOR=#0000BB]<?php [/COLOR][COLOR=#007700]print [/COLOR][COLOR=#0000BB]$year_diff[/COLOR][COLOR=#007700]; [/COLOR][COLOR=#0000BB]?>[/COLOR][/COLOR] </p>
</div>

Thanks for the reply.
But i found it.

$age = floor((time() - strtotime($birthdate))/(60*60*24*365.2425));

i m not implement this. but i think it works.

thanks

That code is not sufficient. may be it will work....i am not sure but you have another code also what i suggest you before.
