Again, I'm not clear on what you are trying to serve. We probably
have to back up to the beginning and erase the assumption that PHP
has a one-to-one correspondence between a URL (or page) and a PHP
file. Having erased that, we have to ask what kind of content you
are trying to serve, then we have to look at PHP examples.
Here's a simple example: a news site backed by a database. URLs like
http://www.example.com/news/2007/07/05
http://www.example.com/news/2007/07/06
http://www.example.com/news/2007/07/07
http://www.example.com/news/2007/07/08
...
return pages which contain that day's headlines extracted from the
database.
One script, no more, must handle all dates. (I don't really care if
there are 2 or 3 scripts, but I do not want to have to write a
separate page for each URL. The number of PHP scripts must be finite
and fixed. It should not increase with the number of URLs the script
services.)
The only way I've ever seen this done in PHP is by using mod_rewrite,
though they're a couple of other interesting suggestions in the thread
I need to explore further. Do you have a suggestion?
Typical MVC front controller. A "news" script like /news/index.php gets
passed 2007 07 and 05 as params via the front controller, so one script
handles all news/year/month/day URLs. Most frameworks provide an MVC
front controller.
For me (a search engine optimizer) the core questions come later... how
does that MVC front controller handle "exceptions" like:
/news/2007 (missing params) -> should 301 to default URL like
/news/2007/01/01/ or throw a 404
/news/dfsrdf/07/06 (invalid year) -> 404 error
/news/ -> either 301 to default URL like /news/2007/01/01/ or throw a 404
/news -> 301 redirect to /news/ ? Too much redirection... either 301 to
default URL like /news/2007/01/01/ or throw a 404
/news/2007/07/07 (no trailing slash) -> 301 to trailing slash version
/news/2007/07/07/
/news/2007/06/07/whatever (excess params) -> 404
Admittedly, not many PHP coders care about such things. Some actually
think flexible dispatching is a feature! Imagine that! ;-)
