PHP写MySQL数据 实现代码
PHP向MySQL数据库中写入数据有三个步骤:
1,PHP和MySQL建立连接关系
2,打开MySQL数据库
3,接受页面数据,PHP录入到指定的表中
1、2两步可直接使用一个数据库链接文件即可:conn.php
复制代码 代码如下:
mysql_connect("localhost","root","");//连接MySQL
mysql_select_db("hello");//选择数据库
?>
当然,前提是已经安装WEB服务器、PHP和MySQL,并且建立MySQL表“cnbruce”
mysql_connect()中三个参数分别为MySQL地址、MySQL用户名和MySQL密码
然后就是通过WEB页面传递数据,让PHP通过SQL语句将数据写入MySQL数据库指定的表中,比如新建文件 post.php
复制代码 代码如下:
require_once("conn.php");//引用数据库链接文件
$uname = $_GET['n'];//GET方法为URL参数传递
$psw = $_GET['p'];
$psw=md5($psw);//直接使用MD5加密
$sql = "insert into members(username,password) values ('$uname','$psw')";
mysql_query($sql);//借SQL语句插入数据
mysql_close();//关闭MySQL连接
echo "成功录入数据";
?>
测试页面: http://localhost/post.php?n=cnbruce&p=i0514
即可向MySQL数据库hello的members表中插入新的数据“cnbruce”到username字段、“i0514”到password字段

MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.

PHP remains important in modern web development, especially in content management and e-commerce platforms. 1) PHP has a rich ecosystem and strong framework support, such as Laravel and Symfony. 2) Performance optimization can be achieved through OPcache and Nginx. 3) PHP8.0 introduces JIT compiler to improve performance. 4) Cloud-native applications are deployed through Docker and Kubernetes to improve flexibility and scalability.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

The reasons why PHP is the preferred technology stack for many websites include its ease of use, strong community support, and widespread use. 1) Easy to learn and use, suitable for beginners. 2) Have a huge developer community and rich resources. 3) Widely used in WordPress, Drupal and other platforms. 4) Integrate tightly with web servers to simplify development deployment.

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

PHP and Python each have their own advantages and are suitable for different scenarios. 1.PHP is suitable for web development and provides built-in web servers and rich function libraries. 2. Python is suitable for data science and machine learning, with concise syntax and a powerful standard library. When choosing, it should be decided based on project requirements.
