What about this, Double-O-Seven?

Code:

stock strreplace2(string[], const find[], const replace[], bool:ignorecase=false, count=cellmax, maxlength=sizeof(string))
{
    if(isnull(find) || isnull(string)) return 0;
    new matches;
    for(new idx, flen = strlen(find), rlen = strlen(replace), pos = strfind(string, find, ignorecase); pos != -1 && idx < maxlength && matches < count; pos = strfind(string, find, ignorecase, idx))
    {
        strdel(string, pos, pos + flen);
        if(rlen) strins(string, replace, pos, maxlength);
        idx = pos + rlen;
        matches++;
    }
    return matches;
}
