How to use PHP to query Baidu index

In SEO optimization, it is essential to understand the status of the website being indexed by search engine spiders. Baidu index is one of the important indicators, and PHP, as a very popular Web programming language, can help us realize the function of querying Baidu index. This article will introduce how to use PHP to query Baidu included volume.

1. Use Baidu Webmaster Platform API interface to implement query

Baidu Webmaster Platform provides an API interface to query the status of a website's inclusion by Baidu based on its URL. The following are the specific implementation steps:

1. Log in to Baidu Webmaster Platform, create a website and bind it.
2. Apply for API permission in "API Authorization" and obtain Access Token.
3. Write PHP code and use Baidu API interface to query the included volume. The code is as follows:

$url = 'http://data.zz.baidu.com/urls?site=[site]&token=[token]'; // API接口
$urls = array('http://www.example.com/'); // 需要查询的URL，可以放在数组中批量查询
$curl = curl_init();
$options = array(
  CURLOPT_URL => $url,
  CURLOPT_POST => true, // POST请求
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_POSTFIELDS => implode("\n", $urls),
  CURLOPT_HTTPHEADER => array('Content-Type: text/plain'),
);
curl_setopt_array($curl, $options);
$result = curl_exec($curl);
curl_close($curl);

$obj = json_decode($result);
echo '收录量：' . $obj->{'success'} . "\n";

In the above code, you need to replace "[site]" and "[token]" Apply for site and API permissions for yourself.

The above code can be implemented by calling the curl extension, and the corresponding extension can be enabled in the php.ini file.

2. Use the "Quick Collection" function of Baidu Webmaster Platform to achieve query

Baidu Webmaster Platform also provides a "Quick Collection" function, which can quickly submit the website URL to speed up the collection, and can Check the inclusion status of the current URL. The following describes how to use PHP to implement queries:

1. Log in to the Baidu webmaster platform and enter the "Quick Collection" page.
2. Enter the URL you want to query in "URL Quick Collection" and submit it.
3. Check the inclusion status of the current URL in "Quick Inclusion Results".

Because the "Quick Collection" function only applies to URLs that are not included in Baidu, you cannot use it to query the inclusion status of included URLs in batches. However, website optimization strategies can be adjusted based on feedback from the inclusion situation to increase the chance of being included by search engines.

This article introduces two methods of querying Baidu's collection volume: one is to use the Baidu Webmaster Platform API interface, and the other is to use the "Quick Collection" function.
