Symfony Flex: Paving the Path to a Faster, Better Symfony
Oct 19, 2017 @ 13:16:52

On the SitePoint PHP Blog, there's a tutorial posted from editor Bruno Skvorc giving an introduction to Symfony Flex and how it is "paving the way" to a more performant future for Symfony.

Symfony Flex is a modern replacement for the Symfony Installer and not the name of the next Symfony version.

Internally, Symfony Flex is a Composer plugin that modifies the behavior of the require and update commands. When installing or updating dependencies in a Flex-enabled application, Symfony can perform tasks before and after the execution of Composer tasks.

The new Symfony will be called just Symfony 4, and while this tutorial will deal only with the Flex tool, it will mention some Symfony 4 upgrades as well.

The tutorial starts with some of the basics about Flex including its current development status and what kinds of things have changed from previous Symfony setups. It then walks you through the creation of a new Flex application including the bootstrapping of the application and the setup and use of application bundles.

Symfony Finland:
PHP 7.1 vs 7.2 Benchmarks (with Docker and Symfony Flex)
Oct 17, 2017 @ 11:17:25

On the Symfony Finland site there's a new post sharing the results of some recent benchmarks of the differences between running the framework on PHP 7.1 and PHP 7.2:

PHP 7.2 will be launching soon, in fact, it has already reached Release Candidate status. I was exploring Symfony Flex with Docker setup and thought I would do a quick round of tests to compare the differences in PHP 7.1 and 7.2 (RC4) regarding performance with a few benchmarks.

[...] The benchmarked application is the Symfony Flex port of the hybrid application I did back in January. The project now has the required configuration to run it with Docker, and you can find the full source on GitHub.

The post then shares some of the results and conclusions of the test runs, showing the differences between the two versions. In one set of tests, they're calling the front page controller with Twig rendering and in the other a backend controller without the display rendering. PHP 7.2 ends up performing slightly better than PHP 7.1 overall but not by very much in most cases. The more dramatic change is on the backend, though, with a good jump in performance for a Symfony Flex application.

Symfony Finland:
Symfony Flex set to enable RAD (Rapid Application Development)
Dec 05, 2016 @ 11:58:37

On the Symfony Finland site there's a post that gets into the details of one of the new advancements in the Symfony ecosystem recently announced by Fabien Potencier at SymfonyCon Berlin 2016 - Symfony Flex.

The Symfony team has acknowledged this gap in their offering. And at SymfonyCon Berlin 2016 project lead Fabien Potencier announced what is known as Symfony Flex. Details are not precise, as I was not attending conference, but the tag line for Symfony Flex is: "Composition over Inheritance"

In essence it seems that Flex will allow for zero-config installation of Bundles. This is done using a Composer plugin. You will simply install packages with Composer and if the Bundle supports it, Composer will also author the necessary integration code and configuration.

As with any new thing, Flex support will start out pretty limited but as it grows in support the community should help it thrive in the Symfony ecosystem. The first release of the tooling for Flex will be available in early 2017.

Authentication Using Zend_Amf
Jul 07, 2011 @ 09:39:47

Kevin Schroeder has a new post to his blog today showing how you can use the Zend_Amf component in your Flex+PHP application to authenticate users with the same authentication structure the rest of the application uses.

I forget why, but a few days ago I started doing some digging around with authentication in Zend_Amf_Server. I had figured that I would add an adapter to the Zend_Amf_Server::setAuth() method and that would be it. But I was wrong.

Zend_Auth is used to validate the login information that's passed along and the Zend_Acl checks to see if they have access. To make this work for a connection from Flex, you need to make an authentication adapter and add it (as well as a basic ACL) into your Zend_Amf_Server call.

Passing typed ActionScript objects to Flex using PHP and a message queue
Jun 07, 2011 @ 08:20:12

Continuing on in his Flex and PHP series Kevin Schroeder has a new post to his blog today looking at how to send typed ActionScript objects to Flex so he could pass PHP objects and their structure directly back to the waiting frontend.

What I wanted to do was use the sales notification mechanism to pass PHP objects to Flex using the message queue. But I could not get the unserialization mechanism to work and so I had to settle for passing a simple message that a sale had been made. However, because you can pass typed objects back and forth between PHP and ActionScript over HTTP using Zend_Amf_Server I figured that there MUST be a way of doing it automatically.

He walks you through the steps to discovery that eventually got him to his end goal - making a simple valueObject class to use for the connection, a basic PHP script (using Zend_Amf) to parse the object's data and a bit of code to send it back to the waiting MQ queue via a Zend_Queue adapter.

Connecting PHP to ActionScript and Flex using Stomp
Jun 06, 2011 @ 08:19:26

Kevin Schroeder has a recent post to his blog today looking at how he used Stomp to connect his backend PHP to frontend Flex, a text-based protocol that can be used to connect to a MQ server instance.

In yesterday's post I talked a little bit about some of the details on how I used messaging to connect a front end on demand request to a back end scheduled data processing mechanism. In this post we're going to talk about how to send data from a web page to a running Flex application without using HTTP. It is really quite easy.

His demo application watches a Magento instance and notifies him whenever a new sales comes in. Because of Magento's event-based system, it made the setup relatively easy. He includes the code for the observer on the Magento side and the Zend Framework-based logger code that it calls. Using the AS3Stomp library to make the connection, Kevin sets up the data provider for the Flex app to push the latest sale information into a list.

Zend Developer Zone:
File uploads with Adobe Flex and Zend AMF
Oct 22, 2010 @ 12:25:07

On the Zend Developer Zone there's a post looking at uploading files in a Adobe Flex-based application that uses a slightly different than usual approach to uploading files through Zend_Amf.

Zend AMF is a PHP implementation of the AMF (Action Message Format) binary protocol within the Zend Framework. I had to implement a system to upload files that were a little different than what is typically used in Flash, so I built upon Zend AMF for my needs. Researching a little on the net, I found a solution that was simpler than I expected. Based on an article, I only had to make a few adjustments.

He shows a (brief) version of his setup - a gateway to be used as the endpoint for Flex to connect to, the VO properties and the class to handle the upload. On the Flex side, he includes the code to create the view and pass the upload off to the waiting PHP backend. If you want to see the full code, you can grab it here.

Zend Developer Zone:
PHP, Flex and Mobile
Sep 08, 2010 @ 09:08:48

On the Zend Developer Zone today there's a new post from Cal Evans about an article from the minds of Ryan Stewart (Adobe) and Kevin Schroeder (Zend) about the powerful combination of Flex and PHP.

These two have gotten together again to show how you can use Flex (Flash, ActionScript, AIR, you know the drill) and Zend Framework (Winner of a BOSSie) Their new article "Flex and PHP" from the most recent issue of Flash & Flex magazine, talks about using the same controllers and actions for returning both HTML and JSON. This concept of programming for multiple destinations is important in a web where your API may be more important than your HTML.

You can get the full article as a PDF from the DevZone site. It's an extended tutorial on getting Flex and PHP to work together via multiple formats (similar to what Kevin presented on his blog recently.

Adobe Developer Connection:
Flex and PHP charting
Aug 06, 2010 @ 09:11:13

On the Adobe Developer Connection there's a recent tutorial posted looking at combining PHP and Flex to make a simple charting application.

One area in which Flex and PHP go really well together is in creating data visualizations. PHP makes it incredibly easy to retrieve information from a database and manipulate it. For its part, Flex provides a user interface layer that is interactive and capable of quickly calculating shapes, which is perfect for charting.

The article focuses on the structure of the data between the PHP application and the Flex frontend (since it needs a bit more definition than some of the usual PHP methods for plotting charts). The files needed to follow along with the tutorial are available for download as well as links to try or buy Flash Builder. In the end, you'll have a chart like this for your efforts.
