How to use PHP to develop automatic website analysis and diagnosis modules in CMS

As the size of the website continues to increase, website management work becomes more cumbersome and complex. Therefore, modules that can automatically analyze and diagnose websites have become an indispensable tool for website managers. In this article, we will introduce how to use PHP to develop automatic website analysis and diagnosis modules in CMS.

1. Functions of the website automatic analysis module

The website automatic analysis module can help administrators regularly check the status of the website and automatically generate reports. This module usually includes the following functions:

• Website link test: Test whether all links are normal, including internal links and external links.
• Page speed detection: Test the loading speed of the page and provide optimization suggestions.
• Accessibility detection: Tests whether the website meets accessibility standards and provides recommendations for fixes.
• SEO Optimization: Conduct basic SEO optimization detection and provide suggestions.

2. Function of the diagnostic module

The diagnostic module can use website logs and exception logs to analyze website anomalies and provide warnings and suggestions. The following are some functions of the diagnostic module:

• Website abnormality log monitoring: detect whether there are abnormalities on the website, including error pages, 404 errors, server errors, etc.
• Security monitoring: Monitor the security status of the website, including malicious attacks, SQL injection and other attacks.
• Detect memory usage: Detect the memory usage of the website and provide relevant suggestions.
• Diagnostic database: Monitor database usage, including space usage and execution speed.

3. Develop CMS website automatic analysis and diagnosis module

When we start to develop the website automatic analysis and diagnosis module in CMS, we need to first determine what we need What data to monitor. For example, if we need to monitor website links, we need to write a link testing script. This script will check all links and store the results in the database. If we need to monitor the website for exceptions, we need to write an exception log script that will capture all exceptions and store them in the database.

Generally, we recommend using scheduled tasks to execute these scripts. For example, we could start the script at 8am every morning and store the results in the database. We can then use another script to generate the report, which will read the data from the database and present it in the form of a report.

The following is an example of a link test script:

$url = 'http://www.example.com/';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($ch);
$error = curl_error($ch);
$http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);

if ($http_code >= 200 && $http_code <= 299) {
  // 正常链接
  // 插入数据库
} else {
  // 非正常链接
  // 插入数据库
}

The above code uses PHP's curl library to test the link. If the link returns an HTTP status code of 200 to 299, the link is normal. Otherwise, it will be considered an abnormal link and inserted into the database. We can test all links using similar code.

4. Conclusion

By using PHP to develop the automatic website analysis and diagnosis module in CMS, we can quickly and efficiently monitor the status of the website, and discover and repair abnormal problems in a timely manner . This will greatly improve the efficiency and level of website management. It should be reminded that this module is only an auxiliary tool and cannot replace the manual monitoring of the website administrator.
