Sure... you could simply add the php word wrap command as follows:
$text = $row_yourQuery['textcolumn'];
$text = wordwrap($text, 50, "\n", true);
echo $text;
The command is wordwrap. You'll notice the "50" is designated for the number of characters. Then comes the line break. Use "true" if you want it to break apart words and "false" if you want to leave words complete before break.
