Question

How could I split a number from end to start?

Considering that the number can have any length.

The closest thing I tried:

$str = "1234"; #or any other number/string ranging from 0 - 99999
#then somehow inverse the number
$arr1 = str_split($str);

if(!empty($arr1[0])){echo "<div ...>".$arr1[0]."</div>";}
if(!empty($arr1[1])){echo "<div ...>".$arr1[1]."</div>";}
if(!empty($arr1[2])){echo "<div ...>".$arr1[2]."</div>";}
if(!empty($arr1[3])){echo "<div ...>".$arr1[3]."</div>";}
if(!empty($arr1[4])){echo "<div ...>".$arr1[4]."</div>";}

Thank you.

Just use strrev function like this:

<?php
    $rev = strrev($str);
?>

Update: One liner to do it all:

$reverse = 
array_map(create_function('$n','return "<div...>$n</div>";'), str_split(strrev($str)));
