First you say anything not PHP then you don't mention one. While I agree that off-request collection may be wiser, I fail to see anything mentioned better than PHP unless you're seriously mentioning Bash to write a webapp like this. Mentioning an old security concern that is no longer an issue seems like an easy way to discount every possible language.
I said that a bash script would be perfect for collecting data periodically and saving it to a file, I wasn't suggesting that you use it to write a web app. I thought that was clear; apologies if it wasn't.
However, you say that this is an easy way to discount every possible language: can you point me to a vulnerability on the same level as register_globals in any other language?
