Detect whether the page is indexed by Baidu through curl in PHP_PHP Tutorial

I need to organize the website recently, and I need to detect which pages in the website are not indexed by Baidu search engine and make relevant adjustments. Since I couldn’t see it clearly by using the site command one by one, I thought of using the PHP program to batch process it. After some research, I found that it is actually very simple. Here is the author’s implementation of using PHP to detect whether a page has been included in Baidu. Share the function.

The following is the specific code:

Copy code The code is as follows:

/*
* Detect whether the webpage is Baidu Included, return 1 means included, return 0 means not included
* @ param string $url URL to be detected
*/
function checkBaiduInclude($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($curl);
if(!strpos($rs,'Sorry, not found')){
return 1;
}else{
return 0;
}
}

The meaning is very simple. For example, if you need to check whether the URL http://www.phpernote.com/javascript-function/833.html is included, you only need:

checkBaiduInclude('http://www.phpernote.com/javascript-function/833.html'); Check it out for yourself.
