Develop a web app on Controlled Documents traceability

I would like to develop a web application Controlled Document System using PHP & MySQL. It is an internal development project. 1. Password protected access to app and log-in history if modifications were made to it
2. Need to manage and keep Controlled Documents traceability visually by each revision 3. Categorize Controlled Documents such as SOP, WI, Forms, Operational text, memory joggers, official templates, Industry standards & specification, etc. 4. Group by Department and Customer specification requirements 5. User should able to tag the history or personalized favorites 6. Documents such as PDF, TEXT, MS Word, MS Excel, video, audio, Jpeg, etc.

Looked into few open application but did not meet my user requirements and we are in tight position & would like to save some $$$.

Any suggestion for web app development is appreciated.
