There’s been lots and lots of discussion regarding the Facebook “Hyper PHP” release of HipHop for PHP. This new technology is an in-production converter for PHP that takes PHP code, converts it into C++ code, and creates a complete binary that can be run on a server natively. Facebook claims improvements of up to 50%, and their model represents a shift in thinking about scripting languages like PHP.
Ostensibly, lots of people are going to be thinking about how this will benefit them and their organizations. Here are some thoughts on who will benefit and who will not benefit.
There are lots of benefits for producers of large-scale web applications written in PHP. The ability to convert PHP code into something else that is more efficient without having to retrain their developers will ultimately reduce server load and deployment costs.
In particular, anyone running a web application with more than two servers will certainly benefit, as there is likely the traffic necessary for such a large web application. With a 50% improvement, one could conceivably use only one server; however, for redundancy reasons, it’s likely a good idea to maintain at least two web servers.
Others who benefit include those who distribute PHP code to clients directly. The ability to deploy an application on a web server in a compiled format ensures that reverse engineering is more difficult and protects intellectual property. There is considerable debate as to whether or not compiled or obfuscated code is worthwhile; given that the product designed by Facebook must be efficient, the idea of distributing a PHP-based binary makes a lot more sense.
Who doesn’t benefit
For all the benefits, there is a large group of PHP developers that won’t benefit: the average, every day developer. There are a vast number of websites that have a single server and not very much traffic; there are also lots of sites that run on shared hosts, or sites that have multiple sites on the same server. Since HipHop runs one web application at a time (with a built-in webserver), it’s impossible at the moment to run more than one website on a box. This is obviously less than optimal for most folks, and will limit adoption.
Also, early adopters of PHP 5.3 won’t be able to use HipHop straight away. Currently, it supports PHP 5.2 (as most of Facebook is written in PHP 5.2), though there are plans to modify HipHop to support PHP 5.3.
HipHop is still pretty awesome, and will certainly change the way PHP applications are developed. There are great opportunities here, and Facebook has certainly developed a revolutionary system. What will ultimately happen remains to be seen; regardless, it should be an exciting year for PHP development overall.
