Using Just One Entry Point For An Entire Dynamic Site

[Seun Osewa]

Hi,

I'm thinking of an architecture for a medium-complexity dynamic site
as follows:

- I use one php file, say a.php as the entry point for the entire
site. PATH_INFO allows me to pass information to my script by using
URLs like http://mysite.com/a.php/user1000 or
http://mysite.com/a.php/images/10.gif and perform the appropriate
action by calling the appropriate function (which may reside in an
included php file)

- I use apache's url rewriting to redirect urls like
http://mysite.com/page25 to a.php b adding the script name -
http://mysite.com/a.php/page25

- Using Smarty to control the actual HTML output.

This seems to me like a sound and obvious way to do things (and also
rarely done) so my questions are:

- Has anyone on this group tried to do or done something like this
before, using one entry point for the entire site for maximum control?

- If so, what do you think are the pros and cons or this approach?

Regards,
Seun Osewa

This pattern is known as "Front Controller" (Martin Fowler, Patterns of
Enterprise Application Architecture), as opposed to "Page Controller",
where you have one .php file for each "page" in the application. There
are a good few applications that use it, like e.g. phpnuke and postnuke.
- If so, what do you think are the pros and cons or this approach?

Don't have the time to go into this now, but this is a very
controversial topic, with followers of both patterns deeply entrenched ;-)

For a start, take a look at this article, which also has some further links:

I just did something like this last night as a test.

I created a dir like this

/mirrors/site1/content
/mirrots/site2/content
in each siteX dir I placed an index.php file

then in my vurtual host conf file I put:
<VirtualHost ......>
ServerName site1.blablabla.com
ServerAlias site2.blablabla.com
DocumentRoot /mirrors/

ErrorDocument 404 /mirrors/
</VirtualHost>
then I put this is /mirrors/
index.php
------------------
<?
$h = $_SERVER['HTTP_HOST']]
$r = $_SERVER['REQUEST_URI'];

if ($r == "/")
$r = "index.html";

if ($h == "site1.blabla.com")
$d = "site1";

if ($h == "site1.blabla.com")
$d = "site2";

readfile("$d$r");
exit();
?>
then I just stuffef plain copies of .html website into the mirrors/siteX

Now the script actualy does the serving, so I can filter it too. or do what
every I want to each request.

This was another one of those, can I do it, a solution, in seach of a
problem.

Thanks.

I finally decided to go with Java because its more natural with this
kind of design with its persistent objects and all.
