strtotime()不返回false

strtotime(" ") doesn't return false when I provide string containing just space or any other character.

Are there any less code solutions to make it return false?

I can't use preg_match, because date formats are all different depending on locale of each user.

http://php.net/manual/en/function.strtotime.php

Returns a timestamp on success, FALSE otherwise. Previous to PHP 5.1.0, this function would return -1 on failure.

Edit: I need to validate the date string, not to trim spaces or other user-provided characters.

    Apply trim() as a workaround to remove leading and trailing whitespace before calling strtotime().

    strtotime(' ') returns current time.

    strtotime('') (strtotime(trim(' '))) returns false.

    This behavior of the function is already reported as a bug and has a fix based on trimming, but it looks like the patch has not yet been accepted by the PHP team for some reason.
