Date difference

[plisken]

How can I find a persons age based on his birthdate?

[xentrix]

<?
$birthday = "19730730"; //in yyyymmdd format

$date = Date ("Ymd");

$age = $date - $birthday;
$age = floor ($age/10000);

echo $age;
?>

thanks, but I forgot to mention that the birth-date format is dd.mm.yyyy

Any ideas? Thanks

try this:

$birthday = "03.30.1983";
$birthday = strtotime($birthday);
$birthday = date("Ymd", $birthday);

$now = date("Ymd");
$age = floor(($now - $birthday)/10000);

echo($age);

strtotime doesn't do the 03.30.1983 well...need to replace the '.'

$birthday = "03.30.1983";
$birthday = str_replace( ".", "/", "$birthday");
$birthday = strtotime($birthday);
$birthday = date("Ymd", $birthday);

$now = date("Ymd");

$age = floor(($now - $birthday)/10000);

echo("<br>$age");
