However, that still would require something like $str[0..mb_strlen($needle)-1] == $needle > Now I see some value in the function, though still perhaps not enough to > justify above and beyond strpos etc. One advantage of the new functions over userland implementations would be efficiency. A strpos() would still require to search the whole string if the $needle is not found. substr() and string slices would require a copy unless that would be optimized, if a general optimization is possible at all. Not sure, if I like to see yet two more string functions in the global namespace, though. -- Christoph M.
