How do I access a hash from an extention/module?

Hi, I am a bit stuck right now, I want to access the values of a global hash (actually it is a session variable) from within my PHP extention/module. So I want to be able to see which keys are defined in a hash, and what the corresponding value in this hash is for each key. Could someone please give me a small example how this is done? I have looked in the source code of the other extentions but I couldn't find anything that could be of any help (I might have missed it though). -- #!perl # Life ain't fair, but root passwords help. # Eric Veldhuyzen eric@terra.telemediair.nl $!=$;=$_+(++$_);($:,$~,$/,$^,$*,$@)=$!=~ # Perl Monger /.(.)...(.)(.)....(.)..(.)..(.)/;$^$~$/$: $^$*$@$~ $_>&$;
