Shared Memory is an efficient mean of exchanging data between applications in the same machine. One application will create a memory portion which other processes can access, as long as they have the proper permissions. You can read more about it here: http://stereochro.me/assets/uploads/notes/dcom3/shmem.pdf
The idea behind SimpleSHM is to keep things very easy to use. If you want better control and flexibility, you can always modify the class or extend it.
<?php
use Simple\SHM\Block;
/**
* Creating new block, with a random ID
*/
$memory = new Block;
$memory->write('Sample');
echo $memory->read();
/**
* Creating new block, with an specified ID
*/
$new = new Block(897);
$new->write('Sample');
echo $new->read();
/**
* Reading an existing block, with the ID of 42
*/
$existing = new Block(42);
echo $existing->read();
