Hello Andi,
there was nothing in this thread that was against adding it besides Sascha
suggestion that following code would do the trick:
function array_has_more($ar) {
if (!is_array($ar)) {
trigger_error("Argument to array_has_more is no array", E_WARNING);
return NULL;
}
next($ar);
$more = key($ar) !== false;
prev($ar);
return $more;
}
Anyway you said that you don't like the name really. Do you have a better
name? If not i'll go with 'array_has_more'.
regards
marcus
