Understanding the PHP async programming model

Before we get into the details of how to develop PHP applications using asynchronous libraries, it's important to step back and have a look at the PHP asynchronous programming model. Understanding the difference between this and the conventional synchronous programming model opens a new world of high performance for you to utilize when developing PHP applications. Let's first have a look at the synchronous programming model, after which we'll dive into async.

Developing synchronous programming code

In traditional PHP programming, code executes in a linear fashion. Once the code has been compiled into machine code, the CPU executes the code one line after another in a sequential manner until the code ends. This is certainly true of PHP procedural programming. Surprising to some, this is also true for object-oriented programming (OOP) as well! Regardless of whether or not you use objects as part of your code, the OOP...
