Apache PHP Code Control Tutorial
It might be tempting to ask, after the event, with web application code on an Apache web server, can controlling code be added to an existing web application codeset, that does not rely on changes to any existent code? The answer is yes, with a lot of provisos …

We were kind of sad and relieved at the same time seeing that to apply this .htaccess approach of allowing for introductory Notification welcome messages up at the RJM Programming domain’s Noughts and Crosses web application we tried it on, but it did not work, whereas trying to apply it to our Apache MAMP (local web server) environment via …
- downloaded existing code to MAMP place in Games/Noughtsandcrosses off the MAMP Document Root folder …
- tweaked the changed tictactoe.js … in a way that suited allowing new introductory Notifications welcoming players in both MAMP and RJM Programming domain brands of Apache web servers, but in different ways … please note that this change to existent code would not have been needed had the RJM Programming domain accepted the .htaccess methodologies, and we were not wanting the same Noughts and Crosses codeset suiting both Apache environments …
- renamed the Games/Noughtsandcrosses index.html (default web application filename) to index.php … to allow for an Apache .htaccess methodology to possibly work (but only does, for us, at MAMP) … it’s only noticed when PHP code is involved (even if there are no starting <?php and ending ?> delimitations in the code, as in our, what was, index.html case) …
- created a 644 permissions .htaccess in Games/Noughtsandcrosses off the MAMP Document Root folder …

… but along the way we wanted to call it …
are_you_happy_with_my_or_do_you_think_my_derriรจre_needs_work.html
… but this didn’t work as an RJM Programming website filename. Rather than make it work, we compromised, and called it (the final) are_you_happy_with_my_or_do_you_think_my_derriere_needs_work.html it ended up as. But this didn’t stop us wondering about all this language and the relationship of these language characters and where and how you can or can’t use those characters outside those usual US-keyboard type characters.
And that brings us to the great MAMP local Apache/PHP/MySql web server product, as a place to experiment, comforted in the knowledge that the Mac OS X Terminal application …

… and knowledge of inodes (all the way to their “extreme case Linux system file removal talents) you can read about at Linux Inode File Removal Tutorial would probably protect me from home grown stupidities.
So what followed for me was a quick look at MAMP’s relevant php.ini file and its httpd.conf configuration files to see that the web server default “goto look for” file list for the web server directory can be altered by a change of …
DirectoryIndex index.html index.php

Within the php.ini configuration file we found interesting, in particular …

Am sure you can feel yourself, there is so much more to explore in this topic area, and we’ll be returning soon to this neck of the woods soon, we hope. In the meantime, take a look at our tutorial picture for a bit of what we did on MAMP with some of these concepts not changing any configuration files at all.
