PHP将PM和AM转换为24小时

问题描述：

所以我需要离开PHP到pm / am到24小时的时间，我们使用Yahoo API来获取汇率，但是他们似乎是在am / pm给我们。

So I need away to in PHP turn pm / am into 24 hour time, We use Yahoo API to get currency rates, but they seem to give it to us by am/pm.

我以为日期可能正常，但是当我阅读这个功能时，将无法将pm转换成24小时。

I thought date might work, but when I read into that function it would had no way to turning pm into 24 hours.

5: 55pm

答

date("H:i", strtotime("5:55 pm"));

如果你想要另一种方式，

and if you want to go the other way,

date("g:i a", strtotime("17:55"));
