Display X number of words

[Anon]

I'm trying to do something that greymatter does, {{entrymainbodyfirstwords x}}.

where x is the number of words you'd want to display

basically, I was wondering how you'd display the first 10, 20, or 30, etc... words in a string

$words = preg_split('/\s/',$string);

$string = '';
for ($i=0;$i<30;$i++) {
if (isset($words[$i])) { //make sure we have something...
$string .= $words[$i];
}
}

echo $string;
