PHP两个时间相差 年/月/日 的计算方法

/**
 * 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');
    $time['a']         = $interval->format('%a');    // 两个时间相差总天数
    return $time;
}


# 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
)
