Hi,

I'm not sure where to look up the answer to this question myself, so
maybe you can help me.

The following line of code works fine with php5:

function CheckMappings(&$badMappings=array())

On a system with php4 the following error is thrown:

Parse error: parse error, unexpected '=', expecting ')' in <phpfile> on
line 42

Now I would like to know, what the problem is. Is it the '&' or the
default value assignment or a combination of both?

Where would I find documentation on the differences in the versions of
php? Is there a good site? Maybe a table with a feature comparison?

Thanks for your help.
Sascha
