PHP is much better than you think

Rants about PHP are everywhere, and they even come from smart guys. When Jeff Atwood wrote yet another rant about PHP, it made me think about the good parts of PHP.

The biggest problem of these rants is that they come from people stuck in the old days of PHP. They either don't care or they don't want to admit that PHP actually evolves at a very fast pace, both at the language level but also at the community level. In fact, it evolves much faster than any other language or web platform. It has not always been the case, but the last 5 years have been an amazing journey for PHP.

Before talking about the amazing things the PHP community has achieved recently, let's have a look at some interesting numbers: PHP is used by 77.9% of all the websites whose server-side programming language is known. WordPress is used by 16.6% of all the websites in the world. If you have a look at the top three CMSes, for the websites that use a monitored content management system: Wordpress is first with 54.3%, Joomla is second with 9.2%, and Drupal is third with 6.8%. Three products written in PHP.

PHP must have done something right, no?

Now, let me tell you a secret, the PHP "tour de force": Despite the changes over the years, PHP is still the easiest language to learn for non-technical people: it allows anyone to create dynamic websites faster than with any other technologies, it allows anyone to host websites cheaply and without any hassles. PHP is probably not the best designed language in the world, but it lets you get things done, and you can't argue with that.

PHP, the Language

PHP 5.0 (released in 2004) brought us a very solid object model... wait a minute, I'm talking about something released almost 8 years ago. Fast forward now. The latest PHP release, PHP 5.4, comes with all the bells and whistles you might dream of in a modern web language: yes, PHP supports namespaces; yes, PHP supports closures; yes, PHP supports traits.

It took some time, but PHP 5.4 also comes with some nice syntactic sugar that makes the whole experience better than ever: yes, PHP supports [] to define arrays; yes, PHP supports calling a method on a newly created object ((new Foo())-bar()); yes, PHP supports getting an array item from any expression ($foo-bar()[1]).

PHP has even learned from its mistakes: register_globals and magic_quotes are definitely gone.

Last, but not the least, PHP even comes with a built-in web server that eases local testing... and it starts in a matter of micro-seconds.

Next challenges: How do we "upgrade" all the old tutorials talking about PHP on the web? What is the best way to support the WebSocket technology in a PHP application?

PHP, the Ecosystem

Having a good language is great, but having a great ecosystem is even better. And the PHP ecosystem has evolved a lot in the last few years.

Git

I won't talk too much about this one. Git is everywhere and PHP embraced Git pretty fast. Almost all major PHP libraries, frameworks, and products are now using Git, including PHP itself.

Composer

Two years ago, I wanted to get rid of my ugly-PEAR-hack I did in symfony 1 to support plugins. I wanted to replace it with something that was able to manage project dependencies, not a global installer like PEAR. Managing dependencies is not an easy task, so I tried to find the best algorithm to manage software dependencies; I had a look at everything: from Perl to Ruby, from Debian to Redhat. Nothing was satisfactory: only homegrown solutions that happen to work... empirically. Then, I stumbled upon ZYpp. That was it. ZYpp uses a SAT solver to manage dependencies. Fast forward. Thanks to the hard work of Nils Adermann and Jordi Boggiano, PHP now has one of the best dependency manager, Composer.

Yes, PHP has a better dependency manager than any other languages.

And thanks to Git, Composer, and the PHP built-in web server, it has never been easier to download/install/test a PHP project.

Want to test Symfony (using PHP 5.4)?

$ composer.phar create-project symfony/framework-standard-edition $ cd framework-standard-edition $ ./app/console server:run
