About Shared Memory
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
Using SimpleSHM
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();
