Reading about PHP frameworks, you'll get a lot about Symfony and Zend Framework. It is true that these frameworks have a lot of features and do great marketing. But what about performance and scalability? There are 2 kinds of frameworks: those written in C as an extension and those written in PHP Using a framework written in C will definitively give the best performance. But fixing (security) bugs and maintaining them requires C knowledge. If the documentation is not complete or incorrect, you might need to read the code to understand the functionality or wait for the maintainer to help you. So if you don't need super high performance, my recommendation is using a framework written in PHP. Here is a test from Laruence (PHP core developer): higher numbers are better, source Here is another test from Zeev Suraski (Zend/PHP core developer): higher numbers are better, source Here is another excellent test from Wang Rui: smaller numbers are better, source (with call graphs, respon...

To handle a lot of traffic, we need a fast controller with very little memory overhead. First, we implement a dynamic controller . The design is based on the micro frameworks Slim and Silex . The first example maps the URL "http://server/index.php/blog/2012/03/02" to a function with the parameters $year, $month and $day: // index.php, handle /blog/2012/03/02 $app = new App(); $app->get('/blog/:year/:month/:day', function($year, $month, $day) { printf('%d-%02d-%02d', $year, $month, $day); }); Our controller is a class named App and uses the get() function to map a GET request. Parameters mapped to the function are marked with a colon. Optional parameters are written inside brackets. Here is an example: // handle /blog, /blog/2012, /blog/2012/03 and /blog/2012/03/02 $app = new App(); $app->get('/blog(/:year(/:month(/:day)))', function($year=2012, $month=1, $day=1) { printf('%d-%02d-%02d', $year, $month, $day); }); Instead of ...
