linux php pdo mysql 扩展
今天在本机部署了一个pdo项目,发现一些问题,真没想到pdo mysql,不容易装啊,哈哈,我说的不容易,是因为php5.3以前版本,yum源里面根本没有。部署后就报,Undefined class constant 'MYSQL_ATTR_INIT_COMMAND'。 1,从网上下pdo_mysql的扩展 下载地址:ht

1,从网上下pdo_mysql的扩展
下载地址:http://pecl.php.net/package/PDO_MYSQL
具体安装请参考:phpize增加php模块
不建议用这种方式安装,看官网说明
Do not use this, as PDO has been moved into core (the php source) so this pecl extension is dead.
This old extension provided a MySQL driver for PDO.
pdo的模块已经封装到php的核心代码里面去了,编译安装的时候,激活就行了。
./configure --with-pdo-mysql --with-mysql-sock=/var/mysql/mysql.sock //mysql sock路径
2,yum安装pdo mysql
php我是用yum安装的,php版本是5.1的,当我安装pdo mysql的时候,报错
yum install php-pdo_mysql
报以下错误:php53-common conflicts with php-common
解决办法:把php-common卸载掉,装php53-common
yum remove php-common yum install php53-common php53 php53-pdo php-pdo_mysql
重起一下php-cgi就可以了。

In MySQL, add fields using ALTERTABLEtable_nameADDCOLUMNnew_columnVARCHAR(255)AFTERexisting_column, delete fields using ALTERTABLEtable_nameDROPCOLUMNcolumn_to_drop. When adding fields, you need to specify a location to optimize query performance and data structure; before deleting fields, you need to confirm that the operation is irreversible; modifying table structure using online DDL, backup data, test environment, and low-load time periods is performance optimization and best practice.

macOS and Linux have their own advantages in compatibility and user experience. macOS has excellent compatibility within the Apple ecosystem, and the user experience is simple and intuitive; Linux has outstanding hardware compatibility and software flexibility. The user experience varies from distribution to distribution, emphasizing personalization and control.

To safely and thoroughly uninstall MySQL and clean all residual files, follow the following steps: 1. Stop MySQL service; 2. Uninstall MySQL packages; 3. Clean configuration files and data directories; 4. Verify that the uninstallation is thorough.

Efficient methods for batch inserting data in MySQL include: 1. Using INSERTINTO...VALUES syntax, 2. Using LOADDATAINFILE command, 3. Using transaction processing, 4. Adjust batch size, 5. Disable indexing, 6. Using INSERTIGNORE or INSERT...ONDUPLICATEKEYUPDATE, these methods can significantly improve database operation efficiency.

MySQL functions can be used for data processing and calculation. 1. Basic usage includes string processing, date calculation and mathematical operations. 2. Advanced usage involves combining multiple functions to implement complex operations. 3. Performance optimization requires avoiding the use of functions in the WHERE clause and using GROUPBY and temporary tables.

Composer is a dependency management tool for PHP, and manages project dependencies through composer.json file. 1) parse composer.json to obtain dependency information; 2) parse dependencies to form a dependency tree; 3) download and install dependencies from Packagist to the vendor directory; 4) generate composer.lock file to lock the dependency version to ensure team consistency and project maintainability.

Use the EXPLAIN command to analyze the execution plan of MySQL queries. 1. The EXPLAIN command displays the execution plan of the query to help find performance bottlenecks. 2. The execution plan includes fields such as id, select_type, table, type, possible_keys, key, key_len, ref, rows and Extra. 3. According to the execution plan, you can optimize queries by adding indexes, avoiding full table scans, optimizing JOIN operations, and using overlay indexes.
