hi

given a text $text and an integer $num_cols, you can do something like this

<?

# split the text into words
$w = preg_split('/\s+/', $text);

# create $num_cols arrays of words
$w = array_chunk($w, ceil(count($w) / $num_cols));

# convert arrays of words back to strings
foreach($w as $k => $v) $w[$k] = implode(' ', $v);

# $w contains $num_cols strings


?>

hope this helps.
