Programming With Yii2 Working With Asset Bundles
June 10, 2015 @ 10:42:30

NetTuts.com is back with another part in their "Programming with Yii2" series today. In this new post they focus on asset bundles, pieces of functionality that let you easily manage things like Javascript and CSS files automatically.

In this Programming With Yii2 series, I'm guiding readers in use of the newly upgraded Yii2 Framework for PHP. In this tutorial, I'll show you how to add custom JavaScript and CSS scripts and libraries to your Yii application. Yii uses a concept it calls Asset Bundles to make it easier to manage these resources. For these examples, we'll continue to build on the simple status application from previous tutorials.

They start with an introduction to asset bundles and how to set them up in the framework and the resulting HTML markup to include the involved files. They show you how to create a simple bundle and load it into your application. A screenshot is included showing a result of the inclusion.

Anthony Ferrara:
Tries and Lexers
May 18, 2015 @ 09:47:32

Anthony Ferrara has an interesting new post to his site talking about tries and lexers, two pieces of a puzzle that are used during script execution. In this case, he's tried his hand at writing a parser which, naturally, lead to needing a lexer.

Lately I have been playing around with a few experimental projects. The current one started when I tried to make a templating engine. Not just an ordinary one, but one that understood the context of a variable so it could encode/escape it properly. [...] So, while working on the templating engine, I needed to build a parser. Well, actually, I needed to build 4 parsers. [...] I decided to hand write this dual-mode parser. It went a lot easier than I expected. In a few hours, I had the prototype built which could fully parse Twig-style syntax (or a subset of it) including a more-or-less standards-compliant HTML parser. [...] But I ran into a problem. I didn't have a lexer...

He starts with a brief description of what a lexer is and provides a simple example of an expression and how it would be parsed into its tokens. He then talks about the trie, a method for "walking" the input and representing the results in a tree structure. He shows a simple implementation of it in PHP, iterating over a set of tokens and the array results it produces. He then takes this and expands it out a bit into a "lex" function that iterates over the string and compiles the found tokens.

From there he comes back to the subject of Javascript, pointing out that it's a lot looser than PHP in how it even just allows numbers to be defined. His testing showed a major issue though - memory consumption. He found that a regular expression method consumed too much and tried compiling out to classes instead (and found it much faster once the process was going).

SitePoint PHP Blog:
3 Ways to Implement Embeddable Custom Badges
December 29, 2014 @ 09:12:38

The SitePoint PHP blog has a recent tutorial showing you how you can use one of three different ways to embed badges into your site. These "badges" are a common practice among sites allowing other sites/applications to embed small statistics such as number of Tweets or Likes about a page.

One great way of organically promoting your application is to provide "badges"; snippets of content that people can embed on their own websites. [...] This can contain up-to-the-minute information from your application about a user, piece of content or another object, dynamically generated and inserted into other websites. In this article I'm going to take a look at some of the ways you can implement this.

He walks you through the creation of a simple application based on Silex, using Twig for template rendering and the WideImage library for creating the images. His datastore, a static array, lists an image, rank and number of "trophies" for each user of the system. He creates a main page showing all of the badges at once, making use of an "iframe" to contain the dynamically created image. He shows how to use the WideImage library to pull in the background, avatar and trophy images, merge them together and add a bit of text with the username and level ranking. Finally he includes the Javascript needed so the remote site can just use a "script" tag to pull in the rendered image and place it on their page.

Thomas Weinert:
FluentDOM 5 + XML Namespaces
August 07, 2014 @ 10:50:22

In this new post to his site Thomas Weinert shows how to use the FluentDOM library (a PHP implementation of a Javascript library by the same name) when XML namespaces are involved.

FluentDOM 5 allows to register namespaces on the DOM document class. These are not the namespaces of a loaded document, but a definition of namespaces for your programming logic.

He compares it to both a PHP example, using the DOMXpath handling and a Javascript sample using its own xmlDocument functionality. Finally he compares these examples to the few lines of FluentDOM code to handle the same kind of evaluation. He wraps up the post with a brief mention of the "appendElement" function that wraps serveral operations in one for easy element additions.

SitePoint PHP Blog:
Getting Started with Assetic
April 14, 2014 @ 10:37:00

The SitePoint PHP blog has a new post from Lukas White today looking at the Assetic asset management library and how you can get started using it in your application.

There was a time when asset management meant little more than inserting a <link> tag or two and a couple of <script> tags into your HTML. Nowadays, though, that approach just won't cut it. There's performance, for one thing. [...] Also, as client-side applications have become more and more sophisticated, managing dependencies amongst scripts and libraries has become increasingly complex. Furthermore, technologies such as Less, Compass and Coffeescript require assets to be compiled, adding yet another step to the process of managing assets. In this article I'm going to look at a PHP package called Assetic which helps manage, compile and optimize assets such as scripts, stylesheets and images.

He briefly discusses asset management first, just to get everyone on the same page as far as what "assets" are and some considerations about their use. Next is an introduction to the Assetic library itself and the install/usage of a simple "AssetCollection" object. He also shows how to add assets to the object and how to configure compression and generation of the files (like with LESS). He also shows how to use the AssetManager and FilterManager object types along with the AssetFactory handler. Finally, he talks about some of the sample output and caching the tool can do with file-based cache handling.

SitePoint PHP Blog:
Integrating Polymer/Dart and Symfony - Part 2
January 21, 2014 @ 13:05:11

On SitePoint's PHP blog Taylor Ren has posted the second part of his series looking at integrating Polymer/Dart and the Symfony framework to make a simple browser-based widget. The first part of the series can be found here.

If the server (and thus the configuration, the programming) is managed by ourselves, the process to get data from a RESTful API from that same server will be simple. We can enable CORS in the returned response header. Done! But if the remote server's RESTful API does not set that header, we will face a CORS error when we try to invoke that API call from within the Dart app.

He offers one solution - JSONP - but dismisses it because of its "hacky nature". Instead he opts to use the PHP (Symfony) side to grab the data from the remote feeds and pull it into the local domain for the widget to fetch. Code for both the client side and server side functionality are included as well as the HTML markup to create the page for the widget.

Integrating Polymer/Dart and Symfony - Part 1
January 15, 2014 @ 10:43:31

On the SitePoint PHP blog today Taylor Ren shows you how to integrate the popular PHP framework Symfony with Polymer/Dart to make a dynamic web application. In this first part of the series, he focuses on just getting things set up and working and creating the first template to populate with data.

In this 2-part series, we are going to look at how to integrate these two powerful tools together, i.e. to run Dart (after compiling to JavaScript) in a Symfony website to add some dynamics. We will also discuss the work-around to avoid JSONP to access data from a remote server where the user has no direct control and the RESTful API called has no CORS enabled. Finally, we will highlight the limitation of the integration and seek the attention of the Dart team to solve the issue and make Dart a better platform.

He starts off with the server-side of things, using Symfony to create a simple template for the site used by the default controller. He then moves to the client-side, showing how to bootstrap Dart and include the resulting Javascript into the page. He includes the markup to add to the page to make things work and the results of his simple "Quote of the Day" application.

PHPClasses.org:
Using Composer to Install JavaScript, CSS & Images Under the Web Document Directory
January 07, 2014 @ 12:36:07

On the PHPClasses.org site today there's a new post showing how to install more than just PHP packages with Composer including things like Javascript, CSS and image files.

By default Composer installs all package files under the vendor directory. If you want to install asset files in the Web document root directory, you need to resort to another solution. This Asset Manager package is a plugin that extends Composer to install any package files outside the vendor directory. Additionally, it can also read the user names and passwords from a configuration file, so you do not have to enter them every time Composer retrieves packages from repositories that may require authentication, like PHP Classes and JS Classes.

Using an asset manager plugin for Composer, he shows how to include an "extra" section into your "composer.json" for the other files. There's also an example of how to implement a custom installation action that, in this case, was used to implement the "extras" functionality. The post finishes up with a look at handling authentication in the Composer requests, using the same tool to parse a "config" section with Basic HTTP authentication information.

PHP.net:
A further update on php.net
October 25, 2013 @ 10:20:05

As many probably noticed yesterday, the entire PHP.net domain (subdomains and all) were marked by the Google Safe Browsing service as potentially harmful. The issue has been discovered and resolved so things are back to normal, but the development group wanted to provide an update as to the current status.

We are continuing to work through the repercussions of the php.net malware issue described in a news post earlier today. As part of this, the php.net systems team have audited every server operated by php.net, and have found that two servers were compromised: the server which hosted the www.php.net, static.php.net and git.php.net domains, and was previously suspected based on the JavaScript malware, and the server hosting bugs.php.net. The method by which these servers were compromised is unknown at this time.

The post talks about some of the actions taken since the compromise and more details about what happened. It all revolved around a malicious Javascript file that was served to some visitors of the site. For more information as it becomes available, check back with the main PHP.net site or follow official_php on Twitter.
