it works when I am testing it on my computer with xampp but when I try to run this on my server it doesn't work. I have Tesseract installed along with ImageMagick and all my php files are set to 775 but I still get an internal server error I feel like it's because i am missing dependencies but I honestly don't know which ones. Thanks for the help!

Question: I am trying to figure out how to fix my internal server error

Start by looking at your server error log. That will tell you what the error is. — , Mar 04 '15 at 00:15
You can find the apache log at: ...\xampp\apache\logs\error.log — Matt Shirley, Mar 04 '15 at 00:17
I said it works fine when I am using it with xampp but when I use it on my server it returns an Internal Server Error 500 — Teirten, Mar 04 '15 at 00:19
Did tesseract compile without errors? https://code.google.com/p/tesseract-ocr/wiki/Compiling. BTW, If you're running xampp you are bound to hit these issues. Might be better to run Virtual box, use a shared folder, and you can run your code on a real environment. — dudeman, Mar 04 '15 at 00:31

PHP Parse error: syntax error, unexpected ')' in test.php on line 134

You have an extra ) on this line

$average_rank = intval(($highrank + $lowrank) / 2));

Should be

$average_rank = intval(($highrank + $lowrank) / 2);

Wow I feel stupid that fixed my problem but now I just gotta figure out how to get Tesseract to work on CentOS sorry for this bad question. – Teirten Mar 04 '15 at 00:43
Looks like you aren't the first on that front http://stackoverflow.com/questions/23792373/installing-tesseract-ocr-on-centos-6 – dudeman Mar 04 '15 at 00:48
