function numDisplay($num){
if ($num >= 11 && $num <= 20){
$str = "10+";
}else if ($num >= 21 && $num <= 30){
$str = "20+";
}
return $str;
} this kind of manual addition seems to be too much.
is there a better way to do this? Automatically follow such rules
function numDisplay($num = 0){
return ($num<10)?$num:strval($num)[0].'0+';
}
-add if the length is unknown-
function numDisplay($num = 0){
return ($num<10)?$num:strval($num)[0].str_repeat('0',strlen($num)-1).'+';
}
