I've took a look about PHP::Session and not seen something interesting for my deal.
I browse cpan yesterday and found the module PHP::Serialization, but i'm not sure it dump a php array.
I've just tried XML::Dumper but it didn't print all informations of my hashes just the first keys.... so i test with Data::DumpXML and everything is ok ^^
Last step, parse this xml file to retrieve an array in my php page

Cheers for yours informations and for this nice website
Best regards Ps: i hope you understand my sad english ^^ i'm french
