1.	What is meant by a library? How can you load a library in CodeIgniter?
Answer» Libraries are packages created in PHP that give higher-level ABSTRACTIONS and thus contribute to faster development. This removes the NECESSITY of focusing on small, minute details by taking care of those by themselves. Three methods are available to create a library: Create an entirely new library Extend native libraries Replace native libraries To load a library in CodeIgniter, you have to include the below code inside a controller: $this->load->library(‘class_name’); All pre-defined libraries developed by CodeIgniter can be obtained at the system/libraries directory. For LOADING multiple libraries at the same time, you can MAKE use of the same code. But replace the parameter with an array for loading multiple libraries. $this->load->library(array(‘library1’, ‘library2’));
