Ahh ... named patterns, how extremely ugly :-)
$date = "/2007/08/06";
preg_match("/(?P<year>[0-9]{4})\/(?P<month>[0-9]{2})\/(?P<day>[0-9]
{2})/", $date, $match);
print_r($match);

Hey,
It so happens I'm working on a CMS component and the 'Many pages one
script' discussion has inspired me to add mod_rewrite capability. I
have a catch-all RewriteRule that just sends everything through
index.php at the top of which I have a "handler table" that maps the
REQUEST_URI to a handler class. I'm using preg_match to do the match
and collect the parameters.
So an example regex looks like:
'@/news/([0-9]+)/([0-9]+)/([0-9]+)@'
This works fine with REQUEST_URIs like:
/news/2007/10/31
but it does not match any of the following:
/news/2007/10
/news/2007
/news
I would like to match these. For example, if the day parameter is not
provided the match array returned by preg_match should simply have
one
fewer elements.
So how does one designate parts of a preg_match expression as
optional?
Mike
How optional? Why use preg_match at all?
list( $app, $year, $month, $day ) = explode( '/', $uri );
