Alright...
The usual changes to scripting languages are changes in functions...
Fair enough. But usually old scripts from the previous version still work. Well, I tested this on 2 servers...
1. Linux Box
- Apache 1.3.x
- PHP5
- MySQL 4.0.20-Max
2. Windows Box
- Apache 1.3.x
- Apahce 2.x
- PHP5
- MySQL 4.0.20-Max
Both returned negative results, errors, and sometimes even failed to complete scripts...
I have to re-write everything I've written for PHP 4.x...
I can't say ASP was much better to me, but PHP3-PHP4 transition was smoother... I'm wondering what happened :S
