[PHP] counting max word length fails on line brake

[andy]

Hi there,

I would like to check user input for to long words. Therefore I did code a
function returning a string seperated by dash if it is more than $maxlength.
If it is 2 times maxlength it returns false.

Works good execept on line brakes. So if the input is:

test
ölakjdfölakjdöfkjaödlfkjöaksdjföl

it asumes thtat the word is: test ölakjdfölakjdöfkjaödlfkjöaksdjföl

Does anybody know why this happens?

Thanx for any help,

andy

function max_word_length($string, $maxlength){
 $word = explode(" ",$string);
 for($x=0;$x<count($word);$x++){
   if (strlen($word[$x]) > 2 * $maxlength)
    return false;

   if (strlen($word[$x]) > $maxlength){
   echo strlen($word[$x]).' '.$word[$x].'<br>';
    $word[$x] = substr($word[$x],0, $maxlength).'-'.substr($word[$x],
$maxlength);
   echo strlen($word[$x]).' '.$word[$x].'<br>';
   }
 }
 return implode(" ", $word);
}
