Does someone know a PHP script to check duplicate content ?

Hello
I'm looking for a script python or PHP who check the duplicate content of texts.
I would like to put it on my hoster and use proxies.
I'm not looking for a plagiarism checker with an API like Copyscape, but a script that I could modify and put on my server.
Thank you very much

Surely this would only work if you used a plagiarism checker with an api? Otherwise the script would need to what - crawl the whole of the internet looking for dupe content?

No just pick up some groups of words of an article, and request it on google.
And check an other article and do the same.

Please explain better. I write PHP. Are you looking for something like this?

This seems to do exactly what you want.

I did not make this script but I tested the Demo out and it does not seem to work anymore. It says everything is Unique. It is not comparing the text content correctly it would seem.


Maybe you can contact the Script creator and have him fix it. Pretty nice script though.
