PHP:如何计算几个月+天的人的年龄？

Question

我想用出生日期计算人的月龄加上几天(例如:1986-08-23).

例如:

0 months and 25 days old.
5 months and 20 days old.
150 months and 4 days old.
285 months and 30 days old.

任何的想法？谢谢.

Answer 1

$date = new DateTime('1990-10-13');
$diff = $date->diff(new DateTime());
printf("%d months and %d days old", $diff->y*12 + $diff->m, $diff->d);

请注意,DateTime::diff()需要PHP 5.3.0或更高版本.
