PHP: Problem with strtotime

问题:

What's going on with strtotime here?

$today = date('m.d.y H:i', time());
echo strtotime($today);

It does not output anything... What's going on?

回答1:

strtotime can only parse certain formats, not any random assortment of numbers and letters. "m.d.y H:i" is not a format strtotime can parse. You'll need to parse that manually using, for example, strptime.

回答2:

Use DateTime::createFromFormat() if you know source format of date ('m.d.y H:i') in your example

print DateTime::createFromFormat('m.d.y H:i',$date)->getTimestamp()

Manual
DateTime::createFromFormat
DateTime::getTimestamp

回答3:

strtotime works with US dates. Try

$today = date('m/d/y H:i', time());
echo strtotime($today);

回答4:

strtotime() is a function for formatting the date, before it is outputted. It seems like the date is already formated in the date() function, and that you make no attempt to format the date in the second line.

Correct code

$today = date("Y-m-d-H.i");
$datenumber = date('Y-m-d',strtotime($today));
$timenumber = date('H.i',strtotime($today));

You can echo all those variables.
