用AM / PM将PHP字符串转换为DateTime [英] PHP String to DateTime with AM/PM

问题描述

是否可以将这种格式为 AH：im / d / y的字符串转换为php中的DateTime？

It is posible to convert my string with this format "A H:i m/d/y" to a DateTime in php?

示例字符串：AM 05:28 13/07/08

Example string: AM 05:28 07/08/13

这不起作用

$date = DateTime::createFromFormat('A H:i m/d/y', 'AM 05:28 07/08/13');

这有效：

$date = DateTime::createFromFormat('H:i m/d/y', '05:28 07/08/13');

$date = DateTime::createFromFormat('H:i m/d/y A', '05:28 07/08/13 AM');

丑陋的解决方法：

$myDate = 'AM 05:28 07/08/13';
$myDate = substr($myDate, 3, strlen($myDate)-3)." ".substr($myDate, 0, 2);

$date = DateTime::createFromFormat('H:i m/d/y A', $myDate);

推荐答案

这是php bug 。尝试使用下一个函数：

This is a php bug. Try to use next function:

function createFromFormat($format, $time)
{       
    $is_pm  = (stripos($time, 'PM') !== false);
    $time   = str_replace(array('AM', 'PM'), '', $time);
    $format = str_replace('A', '', $format);

    $date   = DateTime::createFromFormat(trim($format), trim($time));

    if ($is_pm)
    {
        $date->modify('+12 hours');
    }

    return $date;
}


$date = createFromFormat('H:i m/d/y A', '05:28 07/08/13 AM');
var_dump($date->format('d.m.Y H:i')); //  string(16) "08.07.2013 05:28" 

$date = createFromFormat('H:i m/d/y A', '05:28 07/08/13 PM');
var_dump($date->format('d.m.Y H:i')); //  string(16) "08.07.2013 17:28"
