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

Examples

default
{
    touch_start(integer total_number)
    {
         string source = "Hello there, Ugleh is my name!";
         string mess = stristr(source,"Ugleh",TRUE); //True means after Needle
         llOwnerSay(mess);//outputs  "  is my name!"
         
         mess = stristr(source,"Ugleh",FALSE); //False means before Needle.
         llOwnerSay(mess);//outputs "Hello there, "
    }
}
