CodeIgniter is a powerful PHP framework with a very small footprint,
built for PHP coders who need a simple and elegant toolkit to create
full-featured web applications. If you're a developer who lives in the
real world of shared hosting accounts and clients with deadlines, and if
you're tired of ponderously large and thoroughly undocumented
frameworks, then CodeIgniter might be a good fit. Its goal is to enable you to develop projects much faster than you could if you were writing code
from scratch, by providing a rich set of libraries for commonly needed tasks, as well as a simple interface and
logical structure to access these libraries. CodeIgniter lets you creatively focus on your project by
minimizing the amount of code needed for a given task.
