PHP 7.0 is very very near, if no showstoppers show up during the current Release Candidate #8. And I finally managed to update the package on php-osx.liip.ch, so that you can test and start writing applications on your local OS X machine easily, as well. The installer also automatically does the right thing in the apache configuration with regards to “mod_php7” and “mod_php5”.
Furthermore, since we are using CloudFoundry in one of our bigger projects, I also extended the official PHP buildpack to include PHP 7.0 (and some other things like varnish, but that’s not relevant for this). This way we can easily see, if our apps still work with PHP 7 and do some benchmarks (the initial ones looked promising). To use the buildpack, add the following line to your manifest.yml
and adjust .bp-config/options.json to include (and maybe also change your composer.json to use PHP 7)
Be aware, that I didn’t port many of the extensions the official buildpack includes, so your milage may vary. And if you want to be sure it’s thoroughly tested, maybe better wait for official PHP 7.0 support in the CloudFoundry buildpack. I’m sure, they won’t wait long once it’s is released.
There’s now no excuse anymore to not test your apps against PHP 7.0
The Aggregate pattern is an important part of Domain Driven Design. It prevents inconsistencies and is responsible for enforcing business rules within a collection of objects. For these reasons alone, it is clear to see why it is a key component of a domain model.
Architectural advice recommends that the layer containing the Domain Model be independent from infrastructural concerns. While this is good advice, the Active Record pattern on the other hand wraps a row in the database. Because of this, it is almost impossible to decouple from the persistence layer.
Mixing persistence concerns into a Domain Model can become complex and lead to a lot of bad decisions. This does not mean that it is impossible to create an Active Record Domain Model. In this article, we will work through an example of building an Aggregate which also extends Eloquent: a popular Active Record ORM.
What is an Aggregate?
An Aggregate is a collection of objects which act as a single unit - with one of these objects acting as the Aggregate’s Root. Interaction from outside of the Aggregate must only communicate through the Root object. Aggregate Roots can then manage the consistency of all the objects within its boundary.
Implementing Domain-Driven Design, Vaughn Vernon outlines a set of guidelines in which he calls: “the rules of Aggregate design”:
- Protect True Invariants in Consistency Boundaries
- Design Small Aggregates
- Reference Other Aggregates Only By Identity
- Use Eventual Consistency Outside the Consistency Boundary

Back from Forum PHP Paris 2015.
First, a huge thanks to AFUP for the organization of this great event, as always, reception was beyond reproach.
This event was, once more, a great opportunity for many and rewarding meetings with lot of PHP developers and users.
This year was exceptional, because PHP is 20 years old, AFUP is 15 years old and of course because of upcoming PHP version 7:

Feedback seems good, see joind.id.
I waiting for next meetings.
Phan is the PHP Analyzer for PHP 7 code. I've been using it, partly out of curiosity, and partly to look at what the implications of upgrading my various projects will be. The simplest usage instructions are:
phan -f filelist.txt
I generated my
filelist.txtfiles with a little help from grep - by looking for all files with opening PHP tags in, and putting that list of filenames into a file. My command looks like this:
grep -R -l "<?php" * > filelist.txt
This simply greps recursively (the
-Rswitch) in all files looking for
<?phpand when it finds it, outputs only the filename (the
-lswitch does that bit). Then I just put all the output into my
Phan is in its early stages but it's ready for you to run on your own projects. Look out that you may need to put your bootstrap or other include files first in the
filelist.txtfile if phan isn't finding things in the right order - luckily with it all in one file, it's relatively easy to move things around if you need to.
Generating a File List for Phan was originally published on LornaJane by Lorna. Lorna is a web development consultant, tech lead, author, trainer, and open source maintainer, and she is occasionally available for freelance work.
I was wondering if you might give me a short description of what you see as one of the biggest API problems?
I thought it might be helpful to post my full response, which follows:
One of the most common problems I see in API development is lack of hypermedia, or none at all. By hypermedia, I mean links that describe relationships among data in the API. When hypermedia isn’t used, the API becomes brittle, and those building clients that talk to the API are forced to code to URLs. The URLs become an important interface to the API, and if they change, they break everything. This leads to URL-based versioning schemes, and the only upgrade path for clients is to modify their code to accommodate the new versions.
When an API uses hypermedia, the URLs are no longer important. Clients talking to the API do not need to code to URLs because the API will always convey where to go next through hypermedia relationships. If a URL changes, then there’s no problem. The change gets communicated through the API. This leads to a more flexible and evolvable API that can change over time without needing to update all the clients.
I gave a talk at True North PHP this year that covered this topic. The slides are available for download.

- By Manuel LemosThis is the November edition of the podcast hangout recorded by Manuel Lemos and Arturs Sosins to comment on the latest outstanding PHP Articles and Book Reviews published recently.
They commented on articles about creating Microsoft Word DOCX documents from html, PHP 7 Anonymous classes and nested classes, tracking accesses to your site API using Google Analytics, and reading and writing Microsoft Excel files using PHP stream handlers.
They also commented on the review of the Hack and HHVM book.
Listen to the podcast, or watch the hangout video to learn more about these PHP articles and book reviews.
