NAME PHP::Session - read / write PHP session files SYNOPSIS use PHP::Session; my $session = PHP::Session->new($id); # session id my $id = $session->id; # get/set session data my $foo = $session->get('foo'); $session->set(bar => $bar); # remove session data $session->unregister('foo'); # remove all session data $session->unset; # check if data is registered $session->is_registered('bar'); # save session data $session->save; # destroy session $session->destroy; # create session file, if not existent $session = PHP::Session->new($new_sid, { create => 1 }); DESCRIPTION PHP::Session provides a way to read / write PHP4 session files, with which you can make your Perl application session shared with PHP4. If you like Apache::Session interface for session management, there is a glue for Apache::Session of this module, Apache::Session::PHP. OPTIONS Constructor "new" takes some options as hashref. save_path path to directory where session files are stored. default: "/tmp". serialize_handler type of serialization handler. Currently only PHP default serialization is supported. create whether to create session file, if it's not existent yet. default: 0 auto_save whether to save modification to session file automatically. default: 0 Consider cases like this: my $session = PHP::Session->new($sid, { auto_save => 1 }); $session->param(foo => 'bar'); # Oops, you forgot save() method! If you set "auto_save" to true value and when you forget to call "save" method after parameter modification, this module would save session file automatically when session object goes out of scope. If you set it to 0 (default) and turn warnings on, this module would give you a warning like: PHP::Session: some keys are changed but not modified. NOTES * Array in PHP is hash in Perl. * Objects in PHP are restored as objects blessed into PHP::Session::Object (Null class) and original class name is stored in "_class" key. * Locking when save()ing data is acquired via exclusive "flock", same as PHP implementation. * Not tested so much, thus there may be some bugs in (des|s)erialization code. If you find any, tell me via email.
