- REGULAR EXPRESSIONS (REGEX):
- A regular expression (regex or regexp for short) is a special text string for describing a search pattern. You can think of regular expressions as wildcards on steroids. Regular expressions started out as a feature of the Unix shell. They were designed to make it easier to find, replace and work with strings -- and since their invention, they've been in wide use in many different parts of Unix based Operating Systems. They were commonly used in Perl, and since then have been implemented into PHP.
