How to deploy and maintain a website using PHP
To successfully deploy and maintain a PHP website, you need to perform the following steps: Select a Web server (such as Apache or Nginx) Install PHP Create a database and connect PHP Upload code to the server Set up domain name and DNS Monitoring website maintenance steps include updating PHP and Web servers , back up your website, monitor error logs and update content.
How to deploy and maintain a website using PHP
PHP is a popular web development language that can be used for web-based applications Program and website development. To successfully deploy and maintain a PHP website, there are several key steps to consider:
1. Choose the right web server
Commonly used options include Apache and Nginx, which All are compatible with PHP. Choose an appropriate web server based on desired functionality and performance requirements.
2. Install PHP
Install PHP on the selected web server. Make sure you have the latest version installed and adjust your PHP configuration as needed.
3. Create a database and connect to PHP
If your website requires a database, please create and connect one. PHP provides modules such as MySQLi and PDO to simplify interaction with databases.
4. Upload the code to the server
Upload your PHP code to the web server using a protocol such as FTP or SSH. Organize files into appropriate directories and ensure file permissions are set correctly.
5. Set up domain name and DNS
Register a domain name and point it to the web server. Configure DNS records to resolve the domain to the server's IP address.
6. Monitor your website
Monitor your website regularly to detect any errors or glitches. Set alerts to notify you when problems occur.
Practical case
Deploy a simple message board
- Create a MySQL database and connect to PHP.
- Create a PHP file named
index.php
containing the following code:
<?php // 连接到数据库 $mysqli = new mysqli('localhost', 'root', 'password', '留言板'); // 获取留言 $result = $mysqli->query("SELECT * FROM messages ORDER BY id DESC"); // 输出留言 while ($row = $result->fetch_assoc()) { echo "<div>" . $row['message'] . "</div>"; } // 关闭连接 $mysqli->close(); ?>
- Upload
index.php
Go to the server's/public_html
directory. - Visit the website to view the message board.
Maintain the website
After a website is deployed, regular maintenance is essential to ensure its smooth operation. Here are some maintenance tips:
- Update PHP and Web Server: Install the latest updates regularly to ensure security and improve performance.
- Backup website: Back up your website code, database and other files regularly to prevent data loss.
- Monitor Error Logs: Check the error logs for any issues and take steps to resolve them.
- Update content: Update website content as needed to keep it fresh and relevant.

MySQL query performance can be optimized by building indexes that reduce lookup time from linear complexity to logarithmic complexity. Use PreparedStatements to prevent SQL injection and improve query performance. Limit query results and reduce the amount of data processed by the server. Optimize join queries, including using appropriate join types, creating indexes, and considering using subqueries. Analyze queries to identify bottlenecks; use caching to reduce database load; optimize PHP code to minimize overhead.

Backing up and restoring a MySQL database in PHP can be achieved by following these steps: Back up the database: Use the mysqldump command to dump the database into a SQL file. Restore database: Use the mysql command to restore the database from SQL files.

1. Introduction Over the past few years, YOLOs have become the dominant paradigm in the field of real-time object detection due to its effective balance between computational cost and detection performance. Researchers have explored YOLO's architectural design, optimization goals, data expansion strategies, etc., and have made significant progress. At the same time, relying on non-maximum suppression (NMS) for post-processing hinders end-to-end deployment of YOLO and adversely affects inference latency. In YOLOs, the design of various components lacks comprehensive and thorough inspection, resulting in significant computational redundancy and limiting the capabilities of the model. It offers suboptimal efficiency, and relatively large potential for performance improvement. In this work, the goal is to further improve the performance efficiency boundary of YOLO from both post-processing and model architecture. to this end

How to insert data into MySQL table? Connect to the database: Use mysqli to establish a connection to the database. Prepare the SQL query: Write an INSERT statement to specify the columns and values to be inserted. Execute query: Use the query() method to execute the insertion query. If successful, a confirmation message will be output.

One of the major changes introduced in MySQL 8.4 (the latest LTS release as of 2024) is that the "MySQL Native Password" plugin is no longer enabled by default. Further, MySQL 9.0 removes this plugin completely. This change affects PHP and other app

To use MySQL stored procedures in PHP: Use PDO or the MySQLi extension to connect to a MySQL database. Prepare the statement to call the stored procedure. Execute the stored procedure. Process the result set (if the stored procedure returns results). Close the database connection.

Creating a MySQL table using PHP requires the following steps: Connect to the database. Create the database if it does not exist. Select a database. Create table. Execute the query. Close the connection.

Both Laravel and CodeIgniter support cloud platform deployment. Laravel provides native support out of the box, simplifying the deployment process. CodeIgniter requires additional configuration and modifications to run in a cloud environment.
