Date and time in 24 hours format
提问by Pathik Vejani
I have a date in this format Fri, 15 Jan 2016 15:14:10 +0800, and I want to display time like this 2016-01-15 15:14:10.
我有一个这种格式的日期Fri, 15 Jan 2016 15:14:10 +0800，我想像这样显示时间2016-01-15 15:14:10。
What I tried is:
我试过的是：
$test = 'Fri, 15 Jan 2016 15:14:10 +0800';
$t = date('Y-m-d G:i:s',strtotime($test));
echo $t;
But it is displaying date in this format: 2016-01-15 7:14:10, it should be 2016-01-15 15:14:10.
但它以这种格式显示日期：2016-01-15 7:14:10，它应该是2016-01-15 15:14:10.
How can i do this?
我怎样才能做到这一点？

Use Hinstead:
使用H来代替：
$test = 'Fri, 15 Jan 2016 15:14:10 +0800';
$t = date('Y-m-d H:i:s',strtotime($test));
echo $t;
H: 24-hour format of an hour with leading zeros 00 through 23
H：小时的 24 小时格式，前导零为 00 到 23
G should be the same, but without leading zeroes though. I suspect that your PHP is set to a different timezone than +0800. Can you confirm your timezone (date_default_timezone_get())?
G 应该相同，但没有前导零。我怀疑您的 PHP 设置的时区与+0800. 您能确认您的时区 ( date_default_timezone_get()) 吗？
EDIT
编辑
OP confirmed that his timezone was set to UTC, in which case it maskes perfect sense that it shows 7 in the morning, as dateuses PHPs default timezone.
OP 确认他的时区设置为 UTC，在这种情况下，它掩盖了它显示早上 7 点的完美感觉，因为date使用 PHP 的默认时区。
If you want to "inherit" the Timezone, while getting more flexibility, you should switch to DateTime:
如果你想“继承”时区，同时获得更大的灵活性，你应该切换到DateTime：
echo (new DateTime($test))->format("Y-m-d H:i:s");
