Introduction
It is a standardized way to express patterns to be matched against sequences of characters. some of typical regex parameters are as shown below −
Target sequence (subject) − It is used to searched for the sequence pattern.
Regular expression (pattern) − It is used to searched for in the target sequence.
Matches array − Matches information is stored in one of the special match_results array types (such as cmatch or smatch).
Replacement strin − This operation replaces the matches.
