.htaccess for rewriting a personal system - php

Question

I can't get my head around exactly what I want to do using mod_rewrite.
I want to be able to type in a url such as:
http://site.com/project/project-title/people/alex-coady
or
http://site.com/project/project-title/tasks/task-list-title
which will then be processed at handle.php with the variables available such that:
$_GET['project'] would equal 'project-title'
$_GET['people'] would equal 'alex-coady' (first example)
$_GET['tasks'] would equal 'task-list-title' (second example)
To reiterate: All requests will be managed by handle.php, but if any additional variables are tacked onto the URL, first the keyword people, tasks, projects (and any others I manually add) would be checked and the value immediately after them would be added in the form suggested above.
ie. http://site.com/handle.php?project=project-title&people=alex-coady&tasks= (first example)
Thank you.

Answer 1

How I would handle this is to forget about project,people,tasks and pass everything to the handle.php and then process it there, else you could end up having a rewrite rule for each request you add in the future.
So your mod_rewrite would look like:
RewriteEngine On
Options -Indexes
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ handle.php?route=$1 [L,QSA]
And your handle/router would look something like this (example)
<?php
//Get Route from request
$route = (!isset($_GET['route']))?'':$_GET['route'];
/*Split the parts of the route*/
$parts = explode('/', $route,4);
//http://site.com/project/project-title/people/alex-coady
//http://site.com/project/project-title/tasks/task-list-title
$project = (isset($parts[0]))?$parts[0]:null; //project/
$p_title = (isset($parts[1]))?$parts[1]:null; //project-title/
$action = (isset($parts[2]))?$parts[2]:null; //people or tasks
$sub_action = (isset($parts[3]))?$parts[3]:null; //alex-coady or task-list-title
//Then work with the above variables
?>

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^project/([^/]+)/([^/]+)/([^/]+)$ handle.php?project=$1&people=$2&tasks=$3 [L]
Or
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^project/(.*) handle.php?data=$1 [L]
And in handle.php
list($project, $task, $people, $foo, $bar) = explode('/', $_GET['data]);
