Hacking on PHP 7 with Joe Watkins
In this screencast episode Edd n’ Joe discuss designing language constructs for the PHP 7 core. Following you through firstly a simple ‘hipster’ example, this will give you a good basis to understand the places (Lexer, Parser and Compiler) that will need to be modified to create features that you typically see in RFC proposals.
Now that we have explored all the areas required to implement a new feature, we will now look into some more contrived examples which help expand upon this understanding.
