Simple PHP Quiz
// Fun little quiz
Assuming this string: "January 5th, 2012"
In the shortest amount of code possible, place:
- 'January' within a $month variable
- '5th' within a $day variable
- '2012' within a $year variable.
See if you can accomplish this with one line of code. (And no snarky $month = 'January' answers.
Assume that the format always stays the same, but month, day, and year values can change with each referesh.

Was thinking about doing a fun little quiz/riddle each day. Nothing that will require more than a few minutes.

Do it!

Ironically, this is almost exactly (minus the comma) one of the examples on the PHP manual's sscanf page. :D

Nice quiz. Just know it late :(

@thecrypticace Haha good spot! I still think the preg_split method looks alot nicer than sscanf() even though it's a bit longer (6 chars) !

@JeffreyWay Thanks, didn't know about it. What about non-space separators? Try e.g.

sscanf('2012-25-12', '%d-%d-%d', $y, $m, $d)

It doesn't work. Instead, I'd need:

sscanf('2012-25-12', '%[^-]-%[^-]-%[^-]', $year, $month, $day)

when

list($year, $month, $day) = explode('-' , '2012-25-12');

is ok. Or am I missing something in the sscanf syntax?

// array
date_parse(trim("January 5th, 2012",','));
//vars
extract(date_parse(trim("January 5th, 2012",',')));

Of course, my calendar has 30 months of 12 days each :D

@topdown, what is the point of the trim() since there are no leading/following commas?

Combining @letsallplaygolf with @thecrypticace I get:

extract(date_parse(date('F jS Y')));

@xeoncross trim is stripping the comma
trim has an optional parameter for specifying a character list http://php.net/manual/en/function.trim.php
Wasn't thinking about date_parse already handling it.

@topdown I think @xeoncross was pointing out that trim() only trims characters from the beginning/end of a string, not the middle. So trim isn't required in your code :)

@JeffreyWay Nice teaser though. I didn't know about the sscanf() function.
