How to implement website access log function through PHP and Typecho

Introduction:
For website managers, it is very critical to understand user access behavior and count website traffic. Website access logs record user access information, which can help us analyze user behavior, improve website performance, and optimize user experience. This article will introduce how to implement the website access log function through PHP and Typecho, and provide code samples for readers' reference.

1. Introduction to Typecho
Typecho is a simple and efficient content management system (CMS). It is developed using PHP language and follows the Twiter Bootstrap front-end framework. It has strong customizability, simple development and running speed. Fast and other features. This article will use the Typecho framework as the basis for implementing the website access log function.

2. Database table design
Before starting to write code, we need to design the database table structure to store website access logs.

We can define a database table named "access_log", which contains the following fields:

1. id: primary key, self-increasing;
2. url: accessed by the user URL;
3. ip: the user’s IP address;
4. user_agent: the user’s browser proxy information;
5. referer: the user’s source URL;
6. visit_time : interview time.

You can use the following SQL statement to create this table:

CREATE TABLE access_log (
id int(11) NOT NULL AUTO_INCREMENT,
url varchar(255) NOT NULL,
ip varchar(50) NOT NULL,
user_agent varchar(255 ) NOT NULL,
referer varchar(255) NOT NULL,
visit_time int(11) NOT NULL,
PRIMARY KEY (id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

3. Write PHP code

1. Create a file named "access_log.php" in the theme directory of Typecho File used to record website access logs.
2. In the "access_log.php" file, introduce the core library file of Typecho and write the code as follows:

$db = Typecho_Db::get ();
$options = Typecho_Widget::widget('Widget_Options');
$prefix = $db->getPrefix();

// Get access information
$url = $_SERVER['REQUEST_URI'];
$ip = $_SERVER['REMOTE_ADDR'];
$user_agent = $_SERVER['HTTP_USER_AGENT'];
$referer = isset($_SERVER['HTTP_REFERER ']) ? $_SERVER['HTTP_REFERER'] : '';
$visit_time = time();

// Insert access log into the database
$insertSql = $db->insert ($prefix.'access_log')->rows(array(

'url' => $url,
'ip' => $ip,
'user_agent' => $user_agent,
'referer' => $referer,
'visit_time' => $visit_time

));
$db->query($insertSql);

?>

The above code uses the database operation API provided by Typecho to insert user access-related information into the database table.

4. Verification function

1. Log in to the Typecho backend, select your theme, and find the "header.php" file in the theme directory.
2. In the appropriate location of the "header.php" file, add the following code:

Save and upload the file to the server.

5. View the website access log
Through the implementation of the above code, we have successfully recorded the website access log. Now, we can view the website access log through the following code example:

$db = Typecho_Db::get();
$options = Typecho_Widget::widget(' Widget_Options');
$prefix = $db->getPrefix();

$selectSql = $db->select()->from($prefix.'access_log')-> ;order('visit_time', Typecho_Db::SORT_DESC);
$result = $db->fetchAll($selectSql);

foreach ($result as $row) {

echo 'URL: '.$row['url'].'<br>';
echo 'IP: '.$row['ip'].'<br>';
echo 'User Agent: '.$row['user_agent'].'<br>';
echo 'Referer: '.$row['referer'].'<br>';
echo 'Visit Time: '.date('Y-m-d H:i:s', $row['visit_time']).'<br>';
echo '<hr>';

}
?>

The above code will query all access logs from the database and output them to the page in a simple format for our convenience.

Conclusion:
Through PHP and Typecho, we can easily implement the recording and statistics of website access logs. This will help us better understand user behavior and optimize the website. I hope this article is helpful to you, thank you for reading!
