//Function created by Ugleh Ulrik
string stristr(string haystack, string needle, integer after_needle){

{//we have a haystack, it's not ""
//Now find us a needle!
integer pos = llSubStringIndex(haystack, needle);
if(~pos)
{//We have found a needle!
if(after_needle)//return what comes after needle
return llGetSubString(haystack, pos + llStringLength(needle), -1);
return llDeleteSubString(haystack, pos, -1);
}
