how to highlight search terms

[leegold2]

Commonly done, eg. you enter a word in a search engine and when a
hit-page comes up the search word(s) are highlighted.

I'm doing a fulltext search that works well but I've tried a few
"packaged scripts" and haven't got one to work yet. I'm looking for
straightforward understandable way to do this on my MYSQL/PHP pages.

Thanks,
Lee

To Add: Just to make clear i'm looking for something I can add to my
existing PHP code that does the mysql fulltext search - all works fine.
I want to *add* the hiliting feature. Thanks

If you pass the search term to the page in the url, you could then use
str_replace to replace all instances of the search term. For example:

$output = str_replace($_GET[searchterm],"<font
color=red>".$_GET[searchterm]."</font>",$output);

I'd imagine this'd take up quite a bit of power and take a while to do
on big pages.

Does your search engine return the "coordinates" or the places of
discovery for your search patterns?
Can you iterate through a list where any markup can be added for the
highlighting?

This is exactly how phpbb works. Go to phpbb.com, go to forums, and
search for a term. You will see the term carried in the Query String,
and it is highlighted in the text. Actually php is very fast, and I
would not worry about performance --- takes a lot more resources to
load huge text index, than highlight a few words --at least 1000 to 1
in difference.

Come to think of it, download phpbb, and see how they do it.
