  DESCRIPTION

PHP::MySQL_Session provides a way to read / write PHP4 session data
stored on a MySQL database, 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.

database
    database where session table lives. default: sessions.

table
    database table where session data is stored. default: sessions.

userid
    MySQL user id. default: phpsession.

password
    MySQL password. default: phpsession.

host
    MySQL server host address. default: 127.0.0.1.

serialize_handler
    type of serialization handler. Currently only PHP default
    serialization is supported.

create
    whether to create a session record, if it's not existent yet.
    default: 0 session ID's are generated using
    Digest::MD5:md5_base64(rand(100) . time)

------------------------------------------------------------------------


  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.
