Phalcon is a PHP 5 framework that is implemented as a C extension to offer lower resource consumption and high performance. There's no need to learn or use the C Language, as the functionality is exposed as PHP classes ready to use. As Phalcon is loosely coupled, you're free to use the full framework, or just specific parts of it as glue components. Rather than download an archive, extracting it to a directory like you do with most frameworks, Phalcon can be downloaded and installed as a PHP module. By creating a rich, fully featured framework written entirely in C and packaged as a PHP extension, Phalcon is able to save processor time and boost overall performance. While it is just under two years old, the Phalcon documentation, community and development rival that of many of the more mature frameworks available.
