Yes, yes, and yes. :-)

I was intrigued by your example, so I played around with it some morethis morning. My own quick web search yielded a lot of results forhighlighting search terms, but none that I found did what you'reafter. (I admit I didn't look very deep.) I was up to something likethis before your reply came in. It's still by no means complete. Iteven handles simple English plurals (words ending in 's' or 'es'), butnot variations that require changing the word base (like 'daisy' to'daisies').
<?phpfunction highlight_search_terms($phrase, $string) { $non_letter_chars = '/[^\pL]/iu'; $words = preg_split($non_letter_chars, $phrase);
$search_words = array(); foreach ($words as $word) { if (strlen($word) > 2 && !preg_match($non_letter_chars, $word)) { $search_words[] = $word; } }
$search_words = array_unique($search_words);
foreach ($search_words as $word) { $search = preg_quote($word);
/* repeat for each possible accented character */ $search = preg_replace('/(ae|æ|ǽ)/iu', '(ae|æ|ǽ)', $search); $search = preg_replace('/(oe|œ)/iu', '(oe|œ)', $search); $search = preg_replace('/[aàáâãäåǻāăą](?!e)/iu','[aàáâãäåǻāăą]', $search); $search = preg_replace('/[cçćĉċč]/iu', '[cçćĉċč]', $search); $search = preg_replace('/[dďđ]/iu', '[dďđ]', $search); $search = preg_replace('/(?<![ao])[eèéêëēĕėęě]/iu','[eèéêëēĕėęě]', $search); $search = preg_replace('/[gĝğġģ]/iu', '[gĝğġģ]', $search); $search = preg_replace('/[hĥħ]/iu', '[hĥħ]', $search); $search = preg_replace('/[iìíîïĩīĭįı]/iu', '[iìíîïĩīĭįı]', $search); $search = preg_replace('/[jĵ]/iu', '[jĵ]', $search); $search = preg_replace('/[kķĸ]/iu', '[kķĸ]', $search); $search = preg_replace('/[lĺļľŀł]/iu', '[lĺļľŀł]', $search); $search = preg_replace('/[nñńņňʼnŋ]/iu', '[nñńņňʼnŋ]', $search); $search = preg_replace('/[oòóôõöōŏőǿơ](?!e)/iu','[oòóôõöōŏőǿơ]', $search); $search = preg_replace('/[rŕŗř]/iu', '[rŕŗř]', $search); $search = preg_replace('/[sśŝşš]/iu', '[sśŝşš]', $search); $search = preg_replace('/[tţťŧ]/iu', '[tţťŧ]', $search); $search = preg_replace('/[uùúûüũūŭůűųǔǖǘǚǜ]/iu','[uùúûüũūŭůűųǔǖǘǚǜ]', $search); $search = preg_replace('/[wŵ]/iu', '[wŵ]', $search); $search = preg_replace('/[yýÿŷ]/iu', '[yýÿŷ]', $search); $search = preg_replace('/[zźżž]/iu', '[zźżž]', $search);
$string = preg_replace('/\b' . $search . '(e?s)?\b/iu', '<spanclass="keysearch">$0</span>', $string); }
return $string;
}?>
I still can't help feeling there must be some better way, though.
