Have a "challenge" for you guys...
*This is not homework, an assignment, etc.. this is to help me complete a task that would otherwise take forever and curious if someone could whip out a quick solution*

I have 202 .html files and at the beginning of each file, I need to add a chunk of php code. I could make this myself, but to be honest, it would take me forever and I might as well just manually edit them lol...

All the .html files are in one folder.
Majority of the files begin with this line:

Code:
<?php require_once('Connections/connCJ.php'); ?>
I would like to replace that line with:

Code:
<?php include('mobile_device_detect.php'); mobile_device_detect('http://www.campjellystone.mobi/','http://www.campjellystone.mobi/','http://www.campjellystone.mobi/','http://www.campjellystone.mobi/','http://www.campjellystone.mobi/','http://www.campjellystone.mobi/','http://www.campjellystone.mobi/',false); ?><?php require_once('Connections/connCJ.php'); ?>
If it does not find that line, then nothing is changed on the file. This is important! I can not just simple add that line of text to the beginning of every file, it HAS to find that line before it adds anything.

Can someone knock something out that will do this?

Note: Please don't explain to me how it is done. I KNOW how it can be done, I just think that someone on here could knock it MUCh faster than I could and it would save me a LOT of time.

Thanks!

EDIT: one other thing that would be VERY cool, is if it could add the files that are not edited to a listbox or an outputted text file.
