How can you make in php to see which user has modify his data and how?
DanaFischer
If you want just information on user modifications then it would be no problem as you just need to add 2 columns Last Modified On(use date function) & No of Modifications (put int).
To see changes to the data would require use of logs. Storing changes in database is not recommended.

What is the difference between PHP and ASP.net?
PHP vs ASP.NETBoth PHP and ASP.net are scripting languages designed to be used as a front-end to HTML (allowing server-side processing of web pages and user data prior to sending the HTML to the user's browser). PHP is free and broadly cross-platform (it can be installed and used on any type of server), whereas ASP.net is Microsoft-specific, and fairly expensive. However, ASP.net is somewhat faster than PHP, and works particularly well with Windows clients.ASP.NET is using an XML frontend that is similar to HTML, in order to communicate with .NET libraries..NET code is faster than PHP because it is a precompiled language, whereas PHP is an interpreted language.
