Accessing PHP globals from a module.

Hi, I have just written a module for PHP (in C, linked with PHP statically). Now I need to access session variables and other globals from whithin my module. But I can't find how I should do this, I see documentation on how to call user functions, and how to create new global varables, but now how to access existing globals. Could somebody please tell me where tell me where this is documented if it is documented at all, or explain it to me if it is not documented yet? -- #!perl # Life ain't fair, but root passwords help. # Eric Veldhuyzen eric@terra.telemediair.nl $!=$;=$_+(++$_);($:,$~,$/,$^,$*,$@)=$!=~ # Perl Monger /.(.)...(.)(.)....(.)..(.)..(.)/;$^$~$/$: $^$*$@$~ $_>&$;
