PHP: Is PHP losing popularity?

I was on Quora earlier this week and ran across a question asking Why is PHP losing popularity? along with the elaboration being:

I’ve been keeping my eye on job boards and tech media, and it seems that the new trend is up with Node.js and down with PHP, Ruby staying about the same.
I know every tool has its purpose, but most web applications could be built in any language and framework and fare all the same. PHP is surely scalable, fast enough, safe enough, and heavily supported. Facebook has been happy enough to keep it around, and they have a lot to own up to.

The top two answers basically declare that PHP is on its way out because developers have more options (Ruby, Python NodeJS, etc.) and because the PHP ecosystem is “standing still”. It’s pretty clear that both of these answers are incomplete, if not outright wrong but then where does the truth lie?

Since this isn’t high school there isn’t a universal metric for how to evaluate the popularity of a given programming language. People tend to use things like search trends, job salaries, or the number of questions tagged on StackOverflow. These KPIs are fine for vanity comparisons but they don’t really reveal anything about the velocity, evolution, or enthusiasm for a language or framework. Since we’re concerned specifically with PHP, it’s easier to pick out specific examples that demonstrate its continuing popularity.

Drupal and WordPress

Although treated with disdain by developers, both applications power hundreds of millions of websites. According to Wikipedia, “WordPress is used by more than 18.9% of the top 10 million websites as of August 2013.” and Drupal “is used as a back-end system for at least 2.1% of all websites worldwide”. Which, to put in perspective, are both absolutely staggering numbers. On top of that, Automatic and Acquia, the companies commercially backing WordPress and Drupal, have been raising money and growing at a phenomenal pace.

So what does that mean for PHP? Velocity. With two well funded commercial companies actively developing, selling, and supporting PHP software there will be an increasing number of PHP sites coming online every day.

Symfony, Doctrine, and Zend

In the last few years, all 3 projects have completely overhauled their architectures and rewritten their code bases to incorporate from their respective “version 1s”. A total rewrite is a heroic feat for any project, let alone a popular open source project with thousands of users. All three rewrites have had a positive effect on the PHP community as a whole, including powering new frameworks (Symfony2, Laravel, etc.), enabling consolidation (Drupal 8 powered by Symfony Components), and of course pushing developers to evaluate PHP for new projects.

For PHP, this certainly signals a continuing evolution and a willingness of the community to learn, adapt, and evolve as the web changes.

The Language / PHP Internals

Unfortunately, this is one facet that strongly negatively affects the perception of the PHP ecosystem. Looking at PHP the language, plenty has been written bemoaning the inconsistencies, “wtfs”, and generally bizarre paradigms that the language constructs introduce. Although things have certainly gotten better, a lot of the same issues people were complaining about in PHP4 still exist today with no roadmap for them to be resolved.

Related to the language, is the PHP internals mailing list where core devs discuss language changes and generally how PHP will evolve. Most recently, core dev Anthony Ferrara outlined the major problems with the internals mailing list and generally why he feels the project is in trouble.

The issues with the PHP the language and its apparent lack of real evolution clearly affect the enthusiasm for the ecosystem. Outsiders look in and ask why we’re dealing with a “shitty” language while insiders are stuck defending PHP by pointing to features it got in 5.4 while meekly dodging the fact that there’s still no real unicode support.

So is PHP becoming less popular? Almost certainly not. In the last few years, dozens of interesting new tools and frameworks have been built and at least two VC funded companies have built successful business on software powered by PHP. Unfortunately, the perception of PHP the language as a ghetto is still persistent and the internals team seems to have no plans to change it.
