Required Arguments

  • base: The base string for replace.
  • pattern: The pattern for match in base string.

Optional Arguments

  • flags: Conjuncted value that contains flags ( 1 - ignorecase, 2 - multiline, 4 - dotall, 8 - extended, 16 - unicode ) or ( i - Ignore case, m - Multiline, d - Dotall, e - Extended, u - Unicode )
