Updated on: 2015-04-23
Posted on: 2015-04-23
In a previous article, we learned how to create a simple daemon service in PHP to monitor and process an important activity on a machine in the background.
Now we move with a more advanced topic which is how daemon processes can communicate with other programs, or with other instances of the same daemon process.
Read this article to learn how to perform IPC, Inter-Process communication in PHP to send and receive data using message queues, as well as to transmit large volumes of data using shared memory, an using semaphores to prevent problems caused by simultaneous accesses.

Updated on: 2015-03-22
Posted on: 2015-03-20
Sometimes applications need to filter large amounts of information to show to the user a small subset of relevant data.
However, when the amount data to filter is too large, it may not be feasible to filter the information retrieving the whole data into memory.
Read this article to learn about an alternative approach using a MongoDB document and Symfony listeners to limit the amount of data that needs to be traversed in memory.
