Sorry but this feature is not available in PHP. Script data can be serialized and
written do disk.
Simple types (ints, arrays, floats) can reside in memory and every script can use them
but this is available only
under *nixes. This feature uses SysV semaphores and SysV shared memory. Read the docs
about using this.
The problem occurs with OO scripts because in the memory serialized object will be
stored and on every page request the object
structure will be rebuild. There was a discussion few days before on this list or on
php-dev - I can't remember. A link that you
should visit is http://www.vl-srm.net/index.php
uses SysV semaphores and shared memory, so you can look how they are used in real life
