$url = 'http://www.baidu.com/s?wd=' . $url;

$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$rs = curl_exec($curl);
curl_close($curl);

$arr = parse_url($url);

if (strpos($arr['query'], 'http://')) {
$arr['query'] = str_replace('http://', '', str_replace('wd=', '', $arr['query']));
} else {
$arr['query'] = str_replace('wd=', '', $arr['query']);
}

if (strpos($arr['query'], '?')) {
$str = strstr($arr['query'], '?');
$arr['query'] = str_replace($str, '', $arr['query']);
}

if (strpos($arr['query'], '/')) {
$narr = explode('/', $arr['query']);
$arr['query'] = $narr[0];
}

if (strpos($rs, '<b>'.$arr['query'].'</b>')) {
return 1;
} else {
return 0;
