Result Lengh Limit

[mcmuney]

How do I limit result length. For example, if the full result is a full paragraph text, how would I only show, for example, on the first 100 characters of the paragraph?

[code]

$desc = $_POST['desc'];

$text = substr($desc,0,100);

echo $text;


[/code]

This would show only the first 100 characters.
