PHP查询百度收录与排名

PHP实现批量查询关键词百度收录与排名,演示代码如下:

/*
* 收录、排名
*
* @access public
* @return void
*/
public function checkGather(){
$keyword = urldecode(I(‘get.txt’));
$url = urldecode(I(‘get.url’));
$baiduIP = I(‘get.baiduIP’) ? I(‘get.baiduIP’) : ‘www.baidu.com’;
if(empty($keyword) || empty($url)){
header(‘HTTP/1.0 404 Not Found’);
exit();
}

$data = array(‘index_state’=>0, ‘gather_state’=>0);

//获得网址内容
$gatherContent = @file_get_contents(“http://{$baiduIP}/s?wd=”. urlencode($url) .”&pn=0″);
if(strstr($gatherContent, ‘验证码’)){
preg_match(‘/<input[^>]*name=”url”[^>]*value=”([^>]*)”>/’, $gatherContent, $baiduUrl);
$gatherContent = @file_get_contents($baiduUrl[1]);
}

//检查是否收录
if(!strstr($gatherContent, iconv(‘gbk’,’utf-8′,’没有找到该URL’)) && !strstr($gatherContent, iconv(‘gbk’,’utf-8′,’抱歉，没有找到’))){
$data[‘gather_state’] = 1;
//获得首页内容
$enKeyword = urlencode($keyword);
$indexContent = @file_get_contents(“http://{$baiduIP}/s?wd=$enKeyword&pn=0″);

//首页内容是否出现该域名
$ulrArray = explode(‘.’, $url);
$domain = (count($ulrArray) <= 2) ? str_replace(‘http://’, ”, $ulrArray[0]) : $ulrArray[1];
preg_match(“/$domain/”,$indexContent,$domainExists);

if($domainExists){
$indexArray = preg_split(‘/class=”result[^>]*?id=”\d{1,2}”/’, $indexContent);
array_shift($indexArray);

//循环检查是否存在首页
$p = 0;
$regexCache = ‘/<a[^>]*href=”([^\s]*)”[^>]*>/’;

foreach($indexArray as $v){
$p++;

//获得快照内容
preg_match($regexCache, $v, $indexCacheResult);
$header = get_headers($indexCacheResult[1],1);
$domain = is_array($header[‘Location’]) ? $header[‘Location’][0] : $header[‘Location’];

//匹配URL
if($url == $domain){
$data[‘index_state’] = $p;
break;
}
}

unset($gatherContent);
unset($indexContent);
unset($indexCacheContent);
}
}
echo json_encode($data);
}
