PHP determines whether the URL is included in Baidu

Get started: (Recommended learning: PHP programming from entry to proficiency)

$url = 'https://www.yeguobiji.com/;
echo checkBaidu($url); //如果输出1表示已经收录，-1表示没收录

We can Determine whether the URL is included based on the return value of the checkBaidu method.

/**
* PHP检测url地址是否被百度收录
* @param string    $url 要检测的URL地址
*/
public function checkBaidu($url) {
$url = 'http://www.baidu.com/s?wd=' . urlencode($url);
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$rs = curl_exec($curl);
curl_close($curl);
if (!strpos($rs, '没有找到')) { //没有找到说明已被百度收录
return 1;
} else {
return -1;
}
}
