I modified a script from notes on the eregi_replace() function page. This is a highlight script
that worked good for me.
$text - is the text to search
$words - are the words to highlight (search text)
$the_place - is so that you can tell your users what "area" was searched.
<?php
function highlight_this($text, $words, $the_place) {
$words = trim($words);
$wordsArray = explode(' ', $words);
foreach($wordsArray as $word) {
if(strlen(trim($word)) != 0)
$text = str_ireplace($word, "<span
class=\"highlight\">".strtoupper($word)."</span>", $text, $count);
}
//added to show how many keywords were found
echo "<br><div class=\"emphasis\">A search for <strong>" .
$words. "</strong> found <strong>" . $count . "</strong> matches
within the " . $the_place. ".</div><br>";
//end script modification
return $text;
}
?>
