Fungsi highlightingnya:
function google_hilite($text) {
global $escapeEreg;
$ref = urldecode($_SERVER[HTTP_REFERER]);
// $ref = urldecode("http://www.google.com/?q=gw%20i";);
# let's see if the referrer is google
if (preg_match('/^http:\/\/w?w?w?\.?google.*/i',$ref)) {
# if so, tweezer out the search query
$query = preg_replace('/^.*q=([^&]+)&?.*$/i','$1',$ref);
# scrub away nasty quote marks
$query = preg_replace('/\'|"/','',$query);
# chop the search terms into an array
$query_array = preg_split ("/[\s,\+\.]+/",$query);
# loop through the search terms
foreach($query_array as $b){
$b = strtr($b, $escapeEreg);
if (!preg_match('/<.+>/',$text)) {
# If there are no tags in the text, we'll just do a simple
search and replace
$text = preg_replace('/(\b'.$b.'\b)/i','<span
class="hilite">$1</span>',$text);
} else {
# If there are tags, we need to stay outside them
$text = preg_replace('/(?<=>)([^<]+)?(\b'.$b.'\b)/i','$1<span
class="hilite">$2</span>',$text);
}
}
}
return $text;
}
penggunaannya:
ob_start("google_hilite");
Taruh dimana saja di dalam script anda.
Note: baru nyala kalau diakses melalui google, jadi jgn bilang ngga
nyala ketika anda mengetesnya langsung.
Kalau searching, ya pinternya saja. Kalau saya sih cukup pakai LIKE
'%$input%' saja :)
