CFLib.org – Common Function Library Project

Description:
Based on ListToStruct() from Rob Brooks-Bilson, this one allows the structure key to be repeated. In the case of multiple values for a particular key, a comma-delimited list is created. Useful for parsing strings such as LDAP DNs, which may contain multiple values for a single key.

Return Values:
Returns a struct.

Example:

<cfset tempIn = "a=1;b=2;b=3;c=4">
<cfdump var="#ListToStructRepeatKeys(tempIn,";")#">

Parameters:
