php检测网页是否被百度收录的函数代码

使用：传入一个网址，如 http://www.zzvips.com/news/67000.html，返回1，代表已经收录；返回0，代表百度没有收录。

 

复制代码 代码如下:

<?php
header("Content-type: text/html; charset=utf-8");

 

function checkBaidu($url) {
    $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;
    }
}

echo checkBaidu('http://www.zzvips.com/news/67000.html');
?>

 

上面程序执行结果：
