Hi Marc & all!

Should we check if the function extension_loaded exists before calling it? Or is the @ enough?

'@' is not enough, you have to use "if (@function_exists('extension_loaded'))" to do the work.

And should we do this for every PHP4-specific function we find in the code?

Well, this could be a good idea but in the case of the bug report we're talking about, the problem is a bit more annoying: lots of the functions that exists in php3.0.10+ and php4.0.0 are not implemented in php4.0 beta releases. It means that you have to test each function (even php3 ones) before to use them.... Really painfull.
