Tiny Little Word Display

Nothing superbly complex, but this is quite useful. It takes a variable and displays X amount of words from it. Useful on displaying a preview of something from a database, like on a forum for example. Again, nothing complicated, but useful still.

<?
$thing = "Sweet dreams are made of these, who am i to disagree?";
$new = explode(" ", $thing);
echo "$new[0] $new[1] $new[2]";
?>
