CodeIgniter was released after Rails and at that time the developer listed Rails as being an inspiration. Zend Framework was released after CodeIgniter. I don't know the history of CakePHP and Symfony but Wikipedia shows they were each released in 2005, which was before CodeIgniter but after Rails. That's why I mentioned that Rails was an inspiration for a lot of the PHP frameworks which came out after Rails. Again, there were already PHP web frameworks available, but nothing really took off until after Rails hit the scene.
