Integration of PHP and database monitoring
As a commonly used language in web development, PHP has become the norm in combination with databases. During the development process, we not only need to ensure the normal operation of the program, but also monitor the database to discover and solve problems in a timely manner.
This article will introduce the relevant knowledge and skills of using PHP for database monitoring, including but not limited to the following aspects:
- Monitoring database connection status
- Monitoring database Query execution time and efficiency
- Monitor the load and capacity of the database
- Monitor the security and stability of the database
- Monitor the database connection status
When using PHP to connect to the database, we need to pay attention to the database connection status. Poor connection status may cause the program to fail to run properly and needs to be discovered and resolved in time. The following is a simple code snippet to check the database connection status:
$connection = mysqli_connect($host, $user, $password, $database); if (!$connection) { die("数据库连接错误:" . mysqli_connect_error()); }
With the above code, we can quickly find the problem and fix it when the connection fails.
- Monitoring database query execution time and efficiency
When conducting database queries, we need to pay attention to query execution time and efficiency. When processing a large amount of data, query efficiency may decrease. In this case, the cause needs to be found out and optimized in time.
The following is a simple query execution time monitoring script:
$start = microtime(true); mysqli_query($connection, "SELECT * FROM `table`"); $end = microtime(true); $execute_time = $end - $start; echo "查询执行时间:{$execute_time}秒";
With the above code, we can quickly check the execution time of the query and optimize it.
- Monitor the load and capacity of the database
The load and capacity of the database are key factors affecting program performance and stability. When using PHP to connect to the database, we need to pay attention to the load and capacity status of the database and make timely adjustments.
The following is a simple code snippet to check the load and capacity status of the database:
$status = mysqli_stat($connection); echo "当前连接数:{$status['Threads_connected']}"; echo "当前数据库容量:{$status['Data_length']/1024/1024}MB";
Through the above code, we can quickly understand the load and capacity status of the database, so as to better manage it Adjustment.
- Monitor the security and stability of the database
The security and stability of the database are important factors to ensure the stable operation of the program. When using PHP to connect to the database, we need to pay attention to how to ensure the security and stability of the database.
The following are some commonly used tips to ensure database security and stability:
- Set complex passwords for the database
- Back up the database regularly
- Use a firewall to protect the database server
- Avoid using clear text passwords in PHP to connect to the database
Summary
Through the above introduction, we can see that the relationship between PHP and database monitoring Integration is very important for the stable operation of the program. During the development process, we need to continuously learn and master various techniques and apply them in actual projects. Only in this way can we ensure that our program can run smoothly and achieve the expected results.

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
