Website version 2, keep in PHP or move to .Net? [closed]

Question

I have a website built in PHP 4 with a framework made by hand by me. The code is 3 years old and I am limited (well it requires a lot of effort to make changes).

I decided to do new version of this website. My knowledge has since increased, and now I know that a lot of frameworks exist and that IOC is there and ORM too... The problem is that in all my research, I do not find something that satisfies me completely in PHP. On the other hand, at my job (mostly in .Net winform 2.0) I see many good IOC and other solutions possible, and, I think that .Net is more mature for developing software with best-practices.

I haven't found many good IOC for PHP. As for ORM, I have seen Propel, which looks nice, but haven't found a complete Framework too (Symfony documentation isn't up-to-date, contains lot of error; Zend looks too big I think...), etc.

Do you suggest that I simply try another framework and keep the website in PHP, or would it would be a good idea to switch to .Net?

Reasons of this question

• The system works but has begun to slow down (since it has more users). The database is normalized too much... etc.
• The code isn't bad - business logic is separated of the HTML - but the problem is that controllers are inside the view so it's harder and harder to make some layout changes.
• No unit tests have been done, and it's very "stressful" to make change.
• There's no logging in the system, and it's hard to get a snapshot to see if everything is working properly.

More information (added the 3 nov 2008)

• I know .Net 2.0 this is why my alternative is .Net and not RoR.
• I were suggesting an other language not for the speed issue but for the tool/framework available.
• It's slow because of the database normalisation, too many table that are great in theory but not in practice (we learn from our mistake!)
• It's an hobby, but I take it seriously cause I have over 25 000 users registered since the beginning (not all active).

Current suggestion from people over here

I think I'll keep what I have done and try to do some refactoring slowly. I am surprise that most of the vote have been to keep the current system but well :P this might be the simpler for me for the short term.

Answer 1

If you made the whole framework yourself, I would suggest you just upgrade it for PHP 5 and go forward from there. Most PHP 4 code will "just work" in PHP 5; the exceptions are code that uses the new reserved words, and code that relies on the way PHP 4 differs from PHP 5 -- which means a few things in classes and references at the edge of PHP 4's capabilities.
