PHPMaster.com:
Say Hello to Boris A Better REPL for PHP
April 02, 2013 @ 10:34:00

On PHPMaster.com today Shameer C has a new tutorial introducing you to Boris, a REPL (read-eval-print loop tool) that's a bit more enhanced than the basic PHP interactive shell.

As web developers, we know the importance of the JavaScript console provided by the browser in testing out code snippets. We don't need to write an entire HTML page and JavaScript code just to verify the functioning or logic of a small routine we wrote. Instead, we simply run the expressions in the console and immediately see the results. Similarly, a REPL (Read-Eval-Print Loop) is the console of a programming language in which we can write code line-by-line and see what it does. [...] PHP's REPL is very good in what it does, although it does have some limitations. [...] And so, Boris tries to solve these problems and other concerns as well.

He walks you through the installation (via a git clone and, later, through Composer) and shows how to run it as well as some sample output. He also shows how to make a custom command-line Boris runner and how to embed it into your application. His example of a tool that would benefit from this is a command-line web service client using Boris and Guzzle.
