Utilizing CodeIgniter Resources within Your Library

To access CodeIgniter's native resources within your library use the get_instance() function. This function returns the CodeIgniter super object. Normally from within your controller functions you will call any of the available CodeIgniter functions using the $this construct: $this, however, only works directly within your controllers, your models, or your views.

Regular Expression

In computing, a regular expression is a specific pattern that provides concise and flexible means to "match" (specify and recognize) strings of text, such as particular characters, words, or patterns of characters. Common abbreviations for "regular expression" include regex and regexp. Basic Concepts A regular expression, often called a pattern, is an expression that specifies a set of strings. To specify such sets of strings, rules are often more concise than lists of a set's members.
