On the 9Lessons blog there's a recent tutorial showing you how to log into Instagram via OAuth with the help of their Instagram class.

The very quick registration gives you many users to your web project, we already published login with Facebook, Twitter and Google Plus now time to think about very popular photo sharing portal Instagram. This post explains you how to login with instagram Oauth API and importing user data. Create an instagram account and take a quick look at this demo thanks!

The tutorial walks you through the process of setting up an application in the Instagram service, configuring the scripts with the API key/secret and callback as well as the code for a simple login page. They've also included code to grab the user's information and "popular media" from the web service and pull that information into a local MySQL database.

On Dzone.com today Giorgio Sironi has posted what he considers to be some of the most popular Open Source PHP projects of 2011 including Symfony2, Doctrine and HipHop.

This non-scientific analysis of the popular and exciting PHP projects starts from researches on active projects on SourceForge and GitHub; the latter is where most of the collaboration and involvement of PHP developers is today. I've also crowdsourced the question on Twitter to catch projects I wasn't aware of, and I hope to do the same with you.

Other projects included in his list are:

• Symfony2 Components
• Moodle
• Composer and Packagist
• Drupal, Joomla, Wordpress

Have a project you think he missed? Let him know!

In this post to DZone.com today, John Esposito points out a site that compares popular PHP frameworks socially, a collaborative resource to keep track of things like framework features, popularity and their last update.

There's this wiki-ish comparison of PHP frameworks from socialcompare.com -- presently incomplete, but already containing quite a few frameworks and interesting details of each. You can add comparison criteria (rows; folksonomically) or update existing criteria -- which currently include, among other details, ORM specifics, cache storage, template system, and testing libraries.

Frameworks currently covered include Zend Framework, CakePHP, Fat-Free, Symfony, Yii and Kohana. As it stands now, Yii is the most popular framework with 8 votes and Symfony and Zend Framework are tied for second with 5 points each.

Sameer Borate has posted a simple method for creating a color palette from a given image using just PHP and GD.

In the previous post we saw how we can generate a screenshot from a url. In this post we will see how we can create a color palette of the screenshot (or any other image for that matter) using PHP and GD. This can be useful if you need to quickly get the color scheme of a website or a image. Below are a few example images and their palettes generated using the program.

With the help of his code it's as easy as a call on a GetMostCommonColors object (get_color) to return the hex codes for the values found most. Also included in the post is a sample snippet showing how to pull the details from the file and output it in a grid similar to this.

The Adminxweb site has put together some framework benchmarks for several of the popular frameworks out there, some of which you may not have heard of before.

There are various PHP frameworks and they all have different speeds. The only way to judge a framework by its speed is by benchmarking - conducting tests and comparing the results. [...] Comparing various benchmarks is less of a scientific comparison and more of a subjective application. So in this post, I will review the performance of these frameworks according to the same metrics. This will allow us to arrive at the closest thing there is to an objective winner.

Among the ones they profiled, the DooPHP framework was the only one that came up with a 10 of 10 rating based on speed. It's compared to other frameworks like CodeIgniter, symfony, Solar and the Zend Framework. Take the findings with a grain of salt, however - the author doesn't provide the methods she used to arrive at the numbers. If you would like something with a bit more substance, check out Paul Jones' framework benchmarking tool posted on github.

On NETTUTS.com today there's a new tutorial for the WordPress users/developers out there showing you how to create a "Most Popular By Views" plugin for your site.

As you continue writing for WordPress more and more, the level of difficulty and complexity of your plugins will eventually reach far beyond the simple back-end data manipulation, as demonstrated in our beginner's article. In this installment we'll cover in-depth: database interaction, Admin Widgets, and Sidebar Widgets. Today's example will be a custom built "Most Popular by Views" plugin, which creates an admin area widget for us to view, and a sidebar widget for visitors to see.

Besides waling through the whole process, the tutorial offers a download of the source if you want to get started right away. The resulting plugin can be used on both the admin and public sides of the site as a widget that can be dropped in easily. Code to create both the widget and the database table it needs for a backend are included.

As Andi Gutmans mentions on his blog, the Zend Framework has reached the 10 million downloads mark and is still going strong:

When I started the Zend Framework project back in 2005 I was sure that we could make a difference. Some thought it was a long shot with too ambitious goals, after all I wanted to start from scratch without a single line of code, no community contributors and no corporate contributors. We are now 3.5 years later and I have to say Zend Framework's success has exceeded my own foresight and expectations.

He mentions the teams behind the Framework and some of Zend's partners that have helped to make it an amazing success.

New from the LispCast blog, there's an interesting post that looks at some of the reasons why PHP is so popular among web development circles (but maybe shouldn't be?) after reading this article.

For site like Flickr, Wikipedia, and Facebook - all of whom deal with enormous availability problems - to have stuck with PHP, well, that means something profound. While previously I respected PHP programmers, I always felt that they must not understand much about actual computer science. They were stuck in a procedural world, and a glimpse of what "more advanced" languages could show them would "enlighten" them.

He suggests that PHP scripts, especially the "large libraries" some developers create do some very routine tasks that could be accomplished much simpler. He points out, though, that PHP does have something going for it and that, despite a difference in functionality offered, Lisp could learn something from PHP.

Damien Seguy has released the latest PHP statistics for last month - April 2008. Among the highlights are things like:

• PHP 5.2.5 is now the most popular PHP version, ahead of 4.4.8
• PHP 5 reaches 36.60% of PHP market share
• Still a lot of migrations toward 5.2.5 and 4.4.8

You can check out the details on these and other statistics (like PHP usage by country and version) the complete monthly stats and the evolution stats. Oh, and don't forget - Damien and crew are the ones supplying the latest edition of the elePHPants to the PHP community!
