PHP calculates the number of years, months and days between two dates

<code>/**
 * function：计算两个日期相隔多少年，多少月，多少天
 * param string $date1[格式如：2011-11-5]
 * param string $date2[格式如：2012-12-01]
 * return array array('年','月','日');
 */
function diffDate($date1,$date2)

    $datetime1 = new \DateTime($date1);
    $datetime2 = new \DateTime($date2);
    $interval = $datetime1->diff($datetime2);
    $time['y']         = $interval->format('%Y');
    $time['m']         = $interval->format('%m');
    $time['d']         = $interval->format('%d');
    $time['h']         = $interval->format('%H');
    $time['i']         = $interval->format('%i');
    $time['s']         = $interval->format('%s');

# 使用实例
$sss = diffDate('2015-12-25 12:30:30', '2015-12-26 15:00:00');
print_r($sss);

# 输出
Array
(
    [y] => 00
    [m] => 0
    [d] => 1
    [h] => 02
    [i] => 29
    [s] => 30
    [a] => 1
