substring

I have a search on my php page and it is ok.

With my search result, I highlighted the string target on my content.

$search_tag_text = @preg_replace("/($mysearch)/i", "<u style=\"color:red\">$1</u>", $row->txtContent);

Ok, but is it possible, after having found a string target on my content, to show 20 words before and 20 words after, instead listing all my content?

Any help will be appreciated.
