从XML构建PHP字符串到时间。

I'm trying to convert the following XML into a Time:

我想把下面的XML转换成时间:

 <time hour="18" minute="05" timezone="Eastern" utc-hour="-4" utc-minute="00" />

I'm parsing the XML using SimpleXML, and storing that in a class. I also tried printing out the following:

我使用SimpleXML解析XML，并将其存储在类中。我也尝试打印以下内容:

print strtotime($x->time->attributes()->hour . ":" . $x->time->attributes()->minute) . "<br>\n";

The results I got from that print looked something like this:

我从打印出来的结果是这样的:

1249254300

I guess the result I'm expecting would be either 18:05 or 6:05 PM

我猜我预期的结果是18:05或者6:05

Is there any way I can get it to convert to the style I'm expecting? Also, if I were to add the timezone onto the end is there any way for it to figure that out?

我有什么办法把它转换成我想要的样式吗?另外，如果我把时区加到最后有没有办法让它算出来?

3 个解决方案

#1

I would advise against using strtotime here. Instead try mktime.

我建议不要在这里使用strtotime。而不是尝试mktime。

$time=mktime($x->time->attributes()->hour,$x->time->attributes()->minute,0,0,0,0)

Also you need to format the time stamp (what you printed out was the unix representation). You can do this with the date function.

您还需要格式化时间戳(您输出的是unix表示)。您可以使用date函数来实现这一点。

date("H:i", $time);

#2

You can bring it into a form strtotime() understands (including the timezone info)

您可以将它转换成strtotime()理解的表单(包括时区信息)

<?php
$x = new SimpleXMLElement('<x>
    <time hour="18" minute="05" timezone="Eastern" utc-hour="-4" utc-minute="00" />
</x>');

$ts = sprintf('%02d:%02d %+03d%02d', $x->time['hour'], $x->time['minute'], $x->time['utc-hour'], $x->time['utc-minute']);
$ts = strtotime($ts);
echo gmdate(DateTime::RFC1123, $ts), "\n", date(DateTime::RFC1123, $ts);

My local timezone is CET/CEST (utc+2 in this case), therefore the script prints

我的本地时区是CET/CEST(在本例中是utc+2)，因此脚本打印。

The strToTime function will recognize a date or time in string format, and then convert it to a Unix Timestamp (the number of seconds since the Unix Epoch (the Unix epoch being January 1, 1970 a midnight, UTC).

strToTime函数将以字符串格式识别日期或时间，然后将其转换为Unix时间戳(Unix纪元后的秒数(Unix纪元是1970年1月1日午夜UTC)。

So, what you need to do is take the resul of your strToTime function, and use the date function to format them in a more human readable way

因此，您需要做的是获取strToTime函数的结果，并使用date函数以更人性化的方式格式化它们

//24 hour clock
print date(
      'H:i',
      strtotime($x->time->attributes()->hour . ":" . $x->time->attributes()->minute) . "<br>\n");

//12 hour clock
print date(
      'h:i a',
      strtotime($x->time->attributes()->hour . ":" . $x->time->attributes()->minute) . "<br>\n");

Full formatting options can be found the date entry on php.net

可以在php.net上找到完整的格式化选项。
