Calculating number of years between 2 dates in PHP

Question

I need to get the number of years from 2 dates provided. Here's my code:

function daysDifference($endDate, $beginDate) {    $date_parts1=explode("-", $beginDate);    $date_parts2=explode("-", $endDate);     $start_date=gregoriantojd($date_parts1[1], $date_parts1[2], $date_parts1[0]);    $end_date=gregoriantojd($date_parts2[1], $date_parts2[2], $date_parts2[0]);    $diff = $end_date - $start_date;    echo $diff;    $years = floor($diff / (365.25*60*60*24));    return $years; }  echo daysDifference('2011-03-12','2008-03-09'); 

The $diff gives a number output. When I return $years, am getting 0. What have I done wrong?

Answer 1

$d1 = new DateTime('2011-03-12'); $d2 = new DateTime('2008-03-09');  $diff = $d2->diff($d1);  echo $diff->y;
