I am not C developer. But fairly good in php.
Is it possible to extract details of file (100 %) by using php.
Thanks

Yes, this would be pretty straightforward to do if you are a C developer.

You can use the QUEUE target to queue all HTTP traffic to userland. You 
would then build a userland program to monitor packets for a set of suspect 
keywords.

This approach wouldn't be bullet-proof because the HTTP traffic will be 
fragmented to the MTU size, but it would probably catch 99% of the keywords 
you care about. With a little more code, you could demux the TCP traffic to 
rebuild the entire TCP stream, thereby making it 100%, but that's a lot more 
effort for little return IMO.
