CFLib.org – Common Function Library Project

Description:
Like Ben Forta's reFindAll (which this replaces), except case sensitivity can be toggled and a start position can be defined. Also it returns an array of structs instead of one big struct

Return Values:
Returns an array of structs.

Example:

<cfdump var="#refindall('CAT_([\d]+)','SUBMIT2CAT_1CAT_2CAT_3cat_4',1,false)#">

Parameters:
