问题解决:无法载入MYSQL扩展,请检查PHP配置
phpMyAdmin“无法载入mysql扩展,请检查PHP配置”的解决方法
在配置了PHP的运行环境,并且安装了MySQl数据库之后,下面就可以学习下PHP如何与MySQL进行交互了。
既然MySQL是数据库,则必不可少的需要建立数据库、表、字段等操作(假象下我们使用ASP+ACCESS的情形),然而对于MySQL数据库而言,在我们默认安装时是没有可视化界面操作MySQl的,所以我们很多时候是借助phpMyAdmin来操作MySQL数据库的。
然而通过“PHP 5.2.3 installer”安装版的使用,当我们应用到phpMyAdmin,页面出现了“无法载入mysql扩展,请检查PHP配置”的提示。
1,首先,我们就来检查PHP配置文件 php.ini
打开PHP所安装目录下的 php.ini 文件,Ctrl+F搜索“php_mysql.dll”,将“;extension=php_mysql.dll”前的“;”删除以取消注释,同时搜索并修改“extension_dir”的值为“php_mysql.dll”文件所在文件夹。即:
extension_dir = "D:\PHP\ext\"
extension=php_mysql.dll
2,然而通过这一页所使用的安装版是没有保存PHP扩展DLL文件的ext文件夹的,所以也就没有php_mysql.dll,我们运行phpMyAdmin当然会有问题
继续打开http://www.php.net/downloads.php 选择“PHP 5.2.3 zip package”压缩包文件,将其中的ext文件夹全部解压到PHP的安装目录下,所以才有了extension_dir = "D:\PHP\ext\"(注:前提是你的PHP安装在D盘)
3,完成了对php.ini文件的修改和包含有php_mysql.dll的ext文件夹的添加,建议重新启动下计算机,再来调试phpMyAdmin
4,当然,对于phpMyAdmin文件夹内的config.inc.php文件进行MySQL帐号和密码的修改。
另外,在网络上搜索了下本问题的相关解决方法,有的解决还需要把“php.ini文件和php_mysql.dll拷贝到了c:/windows以及c:/windows/system32目录”内,这是由于PHP是非安装版,一般安装版则不需要了,你可以在“我的电脑”属性“高级”中选择“环境变量”查看系统变量“Path”其中就指明了PHP的安装路径。
phpMyAdmin“无法载入mysql扩展,请检查PHP配置”的问题解决(感谢含笑的指导参考),下面可以学习使用PHP与MySQL交互操作了。

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.

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.

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 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

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.

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 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.
