The requirements listed here are the bare-minimum necessary to a raw PHP set-up, with no extensions. Some of them are related to C compiling, others are about tokenising and parsing, others are accessories depending on which extensions you choose. Preparing environment: packages necessary to compile PHP from source # // we're in! A bash session inside a docker container All commands in this tutorial consider youвЂ™ll be running them inside this container. It will spin up a Docker container with nearly no programs and libraries installed. You donвЂ™t need it for regular development if you donвЂ™t want to, but I strongly advise you to use Docker at least for the first time you compile PHP so youвЂ™ll avoid useless distractions.

Normally youвЂ™d like to run this on your local machine, which can make you fail for thousands of reasons: package version mismatch, broken packages, dependencies that wonвЂ™t allow you to upgradeвЂ¦Д«ecause I really want you to succeed IвЂ™ll just run everything within an empty alpine docker container. Long story short: you can disable most extensions and opt-in to extensions youвЂ™d like to compile. This is particularly useful for running tests and debugging. But you may cherry-pick which extensions youвЂ™ll be compiling for your PHP binary. The main reason IвЂ™m telling you about /Zend and /ext/ is that youвЂ™ll always compile /Zend when compiling PHP.

One way of looking into the /ext/ folder is to think that every extension there is a wrapper to a C library: a portion of C code that makes available to PHP operations only possible in C. String-related functions can be seen here. For example, under /ext/standard youвЂ™ll find all functions that come with standard PHP. Every function and class that exists in PHP comes from this folder. This is a folder for extensions supported by the PHP team.

Nothing much complicated, just have a read рџ‰ If you had no idea PHP had a Virtual Machine, please also consider reading this post that explains about the PHP engine and the Just in Time compiler, it explains how php works from PHP source, through compilation to runtime and will give you the keys to open many other doors in the future. It is responsible for tokenising, parsing, compiling, managing the call stack and, in general, running PHP code. Zend holds the Virtual MachineвЂ™s code, also known as the Zend Virtual Machine (Zend VM). PHPвЂ™s source is split between core (/Zend) and interface (/ext)Д«efore we start I need to give you an oversimplified explanation of PHPвЂ™s folder structure. WeвЂ™ll be visiting the phpвЂ™s source code available on Github. IвЂ™ll certainly post more things about the php core, but if you have a purely PHP background and would like to get more involved without waiting for my posts (which is the correct way), I know that Nuno Maduro will be talking about PHP Internals focused on PHP engineers soon so keep an eye.

Given my limited time between working, writing posts, maintaining my projects AND contributing with PHP source it just makes more sense to me to multiply the knowledge on PHPвЂ™s source instead of trying to decrease the bus factor by one (myself). I write this short guide as an effort inspired by JoeвЂ™s post on the existing Bus Factor present in the language which, in my opinion, is very alarmist but necessary. Once you get familiar with this it will be much easier for you to contribute in many ways such as running tests and uploading reports, writing new tests by yourself and bug reporting/fixing.

Knowing how to compile PHP will open one of the few doors necessary for contributing to the PHP language.
