Rasmus Lerdorf:
A bit of PHP history
Feb 22, 2017 @ 12:55:24

If you were ever interested in the early days of PHP (back in the PHP/FI days, pre-3.0 even) Rasmus Lerdorf has a post sharing an old Changelog he created for some of the first PHP version releases.

Ran across this Changelog from a long long time ago. Read from the bottom up. I added the PHP Tools lines at the bottom for context. So many early decisions made on a whim still affecting us today. And then there are things like "Removed **, // and %% operators" which did a vector dot-product and its inverse, I think. I seem to recall deleting it when I tried to document it.

No years on most of the entries, but version 1.90 was on Sept.18, 1995.

It's an interesting read to see some of the thoughts and additions to the language early on. You can see which functions were added way back then and which ones have been dropped since including an entry for October 17th - "First public release of the code".

Three Devs & A Maybe:
Contributing to PHP with Joe Watkins
Feb 21, 2017 @ 12:15:03

The Three Devs and a Maybe podcast has posted their latest episode featuring returning special guest Joe Watkins to talk about contributing back to the PHP language:

In this weeks episode we chat to good friend of the show Joe Watkins. We start off discussion with his recent work on creating a compute-node, dual WAN setup and accepted PHP Serbia talk on contributing to PHP without being a ‘C wizard’. From here we move on to mention some of the areas (bug tracking system and QA) that could be improved with the help of new contributors within the PHP internals ecosystem. Finally, we highlight several recently proposed RFCs, his opinions on them and some work he is doing on a future RFC.

You can listen to this latest episode either through the in-page audio player or by downloading the mp3 directly. If you enjoy the show be sure to also subscribe to their feed and follow the podcast on Twitter to get updates with new shows are released.

PHP 7.2: The First Programming Language to Add Modern Cryptography to its Standard Library
Feb 14, 2017 @ 12:10:29

In this post to the dev.to site Scott Arciszewski talks about a milestone in the PHP language, it being the first language to "add modern cryptography to its standard library" (PHP 7.2).

Last week, the voting phase closed on an RFC to add libsodium to PHP 7.2. The result was unanimous (37 in favor, 0 against).

When version 7.2 releases at the end of the year, PHP will be the first programming language to adopt modern cryptography in its standard library.

He goes on to talk about what "modern cryptography" is describing concepts like secure primitives and showing example of the high-level API the integration will provide. The post finishes out with a rebuttal against some of the nay-sayers around PHP and its reputation for security. They say that there's "no way PHP is more secure than " so Scott compares this libsodium addition to some of the features in other languages and where they're lacking in relation.

SitePoint PHP Blog:
How to Make Modern PHP More Modern? With Preprocessing!
Feb 03, 2017 @ 11:20:47

The SitePoint PHP blog has posted another tutorial from author Christopher Pitt sharing another one of his "interesting things" you can do with PHP. In this latest article Christopher returns to the idea of "macros" to help with some pre-processing in PHP applications and, ultimately, creating a new language feature without some of the usual overhead.

Let’s have a bit of fun. A while ago, I experimented with PHP macros, adding Python range syntax. Then, the talented SaraMG mentioned an RFC, and LordKabelo suggested instead adding C#-style getters and setters to PHP.

Aware of how painfully slow it can be for an outsider to suggest and implement a new language feature, I took to my editor…

He starts with a brief refresher on macros to do some pre-processing on PHP scripts and allow you to make custom language features that then get interpreted into valid PHP (often with some interesting eval tricks involved). He starts by building a "base" to add in the C# style getters and setters in a special format inside of a class. He includes the macro definitions to set this up and the result once it is passed through the "yay" precompiler. To get around having to run that precompiler every time manually, he creates a custom autoloader to do the job dynamically. He then takes this logic and packages it up so it can be easily installed as a Composer dependency. With this structure in place, he moves on to the creation of a new language feature - the actual functionality for the getter/setters. He ends the post with a screen capture showing the language feature in use and some of the interesting things you can do with it.

Michael Dyrynda:
Switching PHP versions with Laravel Valet
Jan 24, 2017 @ 09:57:40

On his site Michael Dyrynda shows you how to switch PHP versions in Laravel Valet away from the current default of PHP 7.1 (should the need arise).

At the time of writing, Laravel Valet ships with PHP 7.1 but if you're like me, you have some legacy projects around the place that haven't quite lifted their dependencies to PHP 7 just yet.

A lot of folks might have previously used a VirtualBox Virtual Machine, or more recently considered Docker but a lot of the time and especially when dealing with simpler situations, Valet may be all that you need.

Luckily, the combination of Valet and brew on macOS makes switching PHP versions really easy.

With the help of the Homebrew tool it's as easy as telling it to install the PHP version you require and create the link to this needed version. He's included two screencasts in the post to show the process and commands you'll need to accomplish it.

SitePoint PHP Blog:
How PHP Executes – from Source Code to Render
Jan 03, 2017 @ 12:33:41

The SitePoint PHP blog has a new tutorial posted by author Thomas Punt that walks you through the execution of PHP - a "behind the scenes" look at how the PHP processing engine does its magic.

Inspired by a recent article on how Ruby code executes, this article covers the execution process for PHP code. [...] There’s a lot going on under the hood when we execute a piece of PHP code.

He then walks you through the four main steps the engine goes through to turn your PHP code into results: lexing, parsing, compilation and interpretation. For each stage in the process there's a brief description of what piece(s) of the language are doing the work and some examples of how to see the results in more user-land PHP code (like with the AST parser).

Derick Rethans:
Natural Language Sorting with MongoDB 3.4
Dec 16, 2016 @ 09:28:33

Derick Rethans (of MongoDB) has posted an update to his site sharing the details about an improvement that comes with MongoDB 3.4 and is supported by the PHP driver: natural language sorting.

Arranging English words in order is simple—most of the time. You simply arrange them in alphabetical order. Sorting a set of German words, or French words with all of their accents, or Chinese with their different characters is a lot harder than it looks.

[...] Years ago I wrote about collation and MongoDB. There is an old issue in MongoDB's JIRA tracker, SERVER-1920, to implement collation so that sorting and indexing could work depending on the different sorting orders as described for each language (locale). Support for these collations have finally landed in MongoDB 3.4 and in this article we are going to have a look at how they work.

He starts off by explaining a bit about how Unicode collation works and PHP's support through the intl extension in the Collator class. He provides a code example using the class, showing the difference in sorting them first as English words then as Norwegian words. He moves into the MongoDB world and shows how the queries using this new collation support would be structured before moving back to PHP and using the MongoDB client to make the same requests. He also includes examples showing how to set the default locale, the "strength" (for the level of comparison), sorting and some interesting quirks with certain locales.
