With CodeIgniter, you can cut down the amount of code you need to type . This is not just good for lazy, but: less type, fewer mistake, and less time for spend debugging.
On other hand, CodeIgniter is not everything . You can not find engine generator that can build page self. Several frameworks have features like that. For example, they can create web page (that to do basic Create, Read, Update, and Delete operation) automatically. CodeIgniter doesn’t do this.
CodeIgniter Tutorial was created with the following objectives . It was set up from a technical and architectural standpoint :
Progressive Instantiation. In CodeIgniter, components are packed and routines executed only when commanded rather than globally . No assumimg are made by the system regarding what may be needed beyond the minimal core resources, so the system is very light-weight by default. The events, as triggered by the HTTP request, and the controllers and views you design will determine what is invoked.
Loose Coupling. Coupling is the degree to which elements of a system depend on each othe r. The small number of elements depend on each other the more reusable and flexible system
Component Singularity. Singularity is the class to which elements have a narrowly focused objective . In CodeIgniter, each class and its functions are barely autonomous in order to allow maximum usefulness.
