我正在使用此代碼：

$due_date = new DateTime($_POST['due_date']);

$today = new DateTime();

$months = $due_date->diff($today);

$months->format("%m");

$fine = 0.02 * $price * $months; // i got error in this line

$bill = $price + $fine;

我想計(jì)算一下,如果有人遲到,那么他們將每月被罰款.錯(cuò)誤消息是：

Object of class DateInterval could not be converted to int

解決方法:

出現(xiàn)錯(cuò)誤消息是因?yàn)?months不是一個(gè)int,而是一個(gè)類似這樣的Datetime對(duì)象：

DateInterval Object

(

[y] => 0

[m] => 4

[d] => 12

[h] => 6

[i] => 56

[s] => 9

[weekday] => 0

[weekday_behavior] => 0

[first_last_day_of] => 0

[invert] => 0

[days] => 133

[special_type] => 0

[special_amount] => 0

[have_weekday_relative] => 0

[have_special_relative] => 0

)

你可以這樣獲得月份的整數(shù)值

$due_date = new DateTime('13-02-2016');

$today = new DateTime();

$months = $due_date->diff($today);

echo $months->m;

所以基本上你的代碼看起來(lái)像

$due_date = new DateTime($_POST['due_date']);

$today = new DateTime();

$months = $due_date->diff($today);

$fine = 0.02 * $price * $months->m; // i got no error in this line

$bill = $price + $fine;

標(biāo)簽：date-math,dateinterval,datetime,php,date
