Limiting the output of PHP's echo to 200 characters

Question

I'm trying to limit my PHP echo to only 200 characters and then if there are any more replace them with "...".

How could I modify the following statement to allow this?

<?php echo $row['style-info'] ?>

Well, you could make a custom function:

function custom_echo($x, $length)
{
  if(strlen($x)<=$length)
  {
    echo $x;
  }
  else
  {
    $y=substr($x,0,$length) . '...';
    echo $y;
  }
}

You use it like this:

<?php custom_echo($row['style-info'], 200); ?>
