Solution:

To answer with PHP, you can use a function like this one (if you really need to):

<?php
$str = '1234567890123456789012345678901234567890123456789 123456789012345678901234567890123456789012345678901234567890 ASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDF';

function addSpace($str,$int){
 $output = '';
 $words = explode(' ', $str);
 foreach ($words as $word):
     $new = '';
     while(strlen($word)>$int){
     $new .= substr($word, 0, $int). ' ';
     $word = substr($word, $int);
     }
     $output .= "$new $word ";
 endforeach;
 return $output;
}
echo addSpace($str, 50);
?>
