Apache Redirection to a single PHP file

This little snippet was developed when I built a web site to hold date stamped data files. The files are stored based on collection date so the format for the storage is  /data/YYYY/MM/DD/<data-file>.

Rather than using the default Apache indexing system, I wanted to use a custom PHP app developed using a Bootstrap GUI and I did not want to dynamically put an index.php file into every directory to achieve that.

The solution turns out to be rather simple, place 1 index.php file in the document root (/data) and if a URI fetch results in a call to a path with no index.php, force the one in the root to be executed.

Changes do need to be made to the  index.php to collect the URI. This snippet of code below collects the URI, we then need to postfix it to the actual file system root path to get the file system path to the required directory.

function get_path()
{
$uripath = htmlspecialchars($_SERVER[‘REQUEST_URI’]);
if($uripath == “/”)
$dir=”/data/”;
else
$dir=”/data”.$uripath;
chdir ( $dir );
…. do something……
?>

Also note that in my application there are no query parameters after the path. If you need to process query parameters for any reason then you need to strip them from the URI from the “?” onwards.

The vhost file for the defined web site (located in /etc/httpd/vhosts.d/) its pulled in by the httpd.conf file with an Include (along with dozens of others).

<VirtualHost *:80>
ServerAdmin webmaster@dummy-host.example.com
serverName datadump.test.com
DocumentRoot /data
<Directory /data>
Options +Indexes
DirectoryIndex index.php
RewriteEngine on
RewriteCond %{REQUEST_URI} !^/?index.php$
RewriteRule . /index.php
</Directory>
</VirtualHost>

This could also be used if your trying to AutoLoad PHP classes in a large application, I have not tried it yet but logically it should work.
