Array Problem

I thought I understood how to traverse an array, but I guess I was wrong. I
have tried writing the code snippet below as: while, for, foreach... and get
the same (consistently wrong) result each time!

$data is a string variable containing lines of text. Each line is terminated
with a break (<br>). I need to analyze each line to ensure it does not exceed
$maxLength. If it is <= $maxLength do nothing, otherwise truncate the line at
$maxLength minus 3 and add ellipses (...). I then need to reassemble
everything back into a string variable, for later printing. Here is my code:

$line = explode('<br>', $data);
$count = count($line);
$i=1;
while ($i <= $count) {
  $line = (strlen($line)>$maxLength) ? (substr($line,0,($maxLength-3)).'...')
: $line;
  $i++;
}
 $data = implode('<br>', $line);
echo $data;

I know I am forming the array correctly, because $line and $count display as
expected. I know that the ternary is correct, because it produces the desired
result using the original string (i.e., substituting $data outside the
'while' loop).

Any help will be greatly appreciated.
