Answer 1

$searchString = "Google Book";

$originalString = "Search and preview millions of books from libraries and publishers worldwide using Google Book Search. Discover a new favorite or unearth an old classic.";

$outputString = preg_replace("/($searchString)/i",'<strong>${1}</strong>',$originalString);

This should do a case-insensitive search and replace of your search string so that it becomes wrapped by <strong> tags.

Note, however, it will not match if you provide a search string of “Google Books” (note the ‘s’). This is very basic, there is no stemming to account for variations of words / plurals etc nor does it check for word boundaries (ie you could search for ‘oogl’ and it will match Google). Depending on your requirements, this might be sufficient though.
