snippet generation in php

Question

Hi,

I have a long chunk of text that came back from a search query. I'd like to display a snippet of the text, not the entire thing, and highlight the search query within the snippet. I realize that decided what part of the text to slice can be complicated, and I was hoping for any ideas on how do to this?

Thanks!

$text = "

";

$query = "the text";

preg_match("~\b.{0,20}$query.{0,20}\b~", $text, $m);
echo str_replace($query, "<strong>$query</strong>", $m[0]);
