PHP Carbon diffInMonths

Question

我有一个PHP函数的问题。在某些情况下，我得到了错误的结果。例如：

$start = \Carbon\Carbon::create(2017, 4, 1);
$end   = \Carbon\Carbon::create(2017, 5, 1);

echo $start->diffInMonths($end);

我应该得到1，但我得到了0。我使用的是PHP7.1和Laravel 5.4。

有没有人有同样的问题？我怎么才能修复它？谢谢你的帮助!

Answer 1

$start = \Carbon\Carbon::create(2017, 4, 1);
$end   = \Carbon\Carbon::create(2017, 5, 1);

echo round($start->floatDiffInMonths($end));

Answer 2

正如github上的碳问题所说的那样，这是一个错误。这是more。

<?php
$d1 = new DateTime("2015-03-01 00:00:00.000000", new DateTimeZone('Europe/London'));
$d2 = new DateTime("2015-05-01 00:00:00.000000", new DateTimeZone('Europe/London'));

$diff = $d2->diff($d1);

print_r($diff);

输出

DateInterval Object ( [y] => 0 [m] => 1 [d] => 30 [h] => 0 [i] => 0 [s] => 0 [f] => 0 [weekday] => 0 [weekday_behavior] => 0 [first_last_day_of] => 0 [invert] => 1 [days] => 61 [special_type] => 0 [special_amount] => 0 [have_weekday_relative] => 0 [have_special_relative] => 0 )
