25 | 26 | `MysqlHelper` 是一个便捷的`通过PHP导入和导出Mysql数据库表结构和数据`的工具,可以快速实现mysql的数据库的导入和导出. 此类库旨在提供轻量化便捷的mysql导入导出, 开发初衷是web应用安装程序和插件类应用的数据结构导入. 因此没有做数据分批, 大量数据的导入导出并不适合. 27 | 28 | ## 🧩特性 29 | 30 | - 简单易用: 仅依赖`mysqlli`扩展,`开箱即用` 31 | - 灵活操作: 兼容主流框架,使用更方便 32 | - 长期维护: 作者为自由职业者,保证项目的`长期稳定`和`持续更新` 33 | 34 | ## 🚀安装 35 | 36 | 通过Composer导入类库 37 | 38 | ```bash 39 | composer require zjkal/mysql-helper 40 | ``` 41 | 42 | ## 🌈使用文档 43 | 44 | ### 1. 实例化 45 | 46 | *方式一: 常规方法* 47 | 48 | ```php 49 | use zjkal\MysqlHelper; 50 | 51 | $mysql = new MysqlHelper('root', 'passwd', 'dbname', '127.0.0.1', '3306', 'utf8mb4', 'wp_'); 52 | ``` 53 | 54 | *方式二: 实例化后,通过setConfig方法设置数据库配置* 55 | 56 | ```php 57 | $mysql = new MysqlHelper(); 58 | $mysql->setConfig(['username' => 'root', 'password' => 'passwd', 'database' => 'dbname']); 59 | ``` 60 | 61 | MysqlHelper针对常用的框架做了兼容,可以直接使用框架的数据库配置, 比如`ThinkPHP`框架或`Laravel`框架 62 | 63 | ```php 64 | $mysql = new MysqlHelper(); 65 | $config = config('database.connections.mysql'); 66 | $mysql->setConfig($config); 67 | ``` 68 | 69 | ### 2. 导出数据 70 | 71 | * 如果实例化时, 已经设置了表前缀,导出的表名可以不用带前缀 72 | 73 | ```php 74 | //导出数据库(包含表结构和数据) 75 | $mysql->exportSqlFile('test.sql'); 76 | 77 | //仅导出数据库表结构 78 | $mysql->exportSqlFile('test.sql', false); 79 | 80 | //导出指定表的结构和数据 81 | $mysql->exportSqlFile('test.sql', true, ['table1', 'table2']); 82 | 83 | //导出数据库所有表,并且添加禁用外键检查的SQL语句 84 | $mysql->exportSqlFile('test.sql', true, [], true); 85 | //php8以上可以更简洁的写法: 86 | $mysql->exportSqlFile('test.sql', disableForeignKeyChecks: true); 87 | ``` 88 | 89 | ### 3. 导入数据 90 | 91 | * 如果需要在导入过程中自定义表前缀, 则sql文件中的表前缀需要使用`__PREFIX__`占位符代替 92 | * 如果实例化时, 已经设置了表前缀, 则可以不用传入第二个参数 93 | * 增加了数据导入时的参数, 用于设置是否删除已存在的表, 默认不删除, 一般用于数据恢复. 94 | 95 | ```php 96 | //导入数据库 97 | $mysql->importSqlFile('test.sql'); 98 | 99 | //导入数据库,并自动替换表前缀 100 | $mysql->importSqlFile('test.sql', 'wp_'); 101 | 102 | //导入数据库,不替换前缀, 并且如果表已经存在,则先删除 103 | $mysql->importSqlFile('test.sql', '', true); 104 | //php8以上可以更简洁的写法: 105 | $mysql->importSqlFile('test.sql', dropTableIfExists: true); 106 | ``` 107 | 108 | ## 📃更新日志 109 | 110 | > v1.0.9 2024年12月5日 111 | > * 增加了数据导入时的参数, 用于设置是否删除已存在的表 112 | 113 | > v1.0.8 2024年11月23日 114 | > * 修复了导入表时重复替换忽略语句的BUG 115 | 116 | > v1.0.7 2024年10月4日 117 | > * 增加导入的稳定性:过滤空行 118 | 119 | > v1.0.6 2024年8月27日 120 | > * 导入时增加了判断是否存在同名表的逻辑 121 | 122 | > v1.0.5 2024年6月14日 123 | > * 增加了在导出时可以设置禁用外键检查的参数 124 | 125 |

25 | 26 | 'MysqlHelper' is a convenient tool for 'importing and exporting Mysql database table structure and data via PHP', which can quickly import and export mysql databases. These libraries are designed to provide lightweight and convenient MySQL import and export, and are developed to import data structures from web application installers and plug-in applications. Therefore, there is no data batching, and the import and export of a large amount of data is not suitable. 27 | 28 | ## 🧩Features 29 | 30 | - Easy to use: only depends on `mysqlli` extension, `out of the box` 31 | - Flexible operation: Compatible with mainstream frameworks, more convenient to use 32 | - Long-term maintenance: The author is a freelancer committed to ensuring the project's `long-term stability` and `continuous updates`. 33 | 34 | ## 🚀Installation 35 | 36 | Install via Composer. 37 | 38 | ```bash 39 | composer require zjkal/mysql-helper 40 | ``` 41 | 42 | ## 🌈Usage 43 | 44 | ### 1. instantiate 45 | 46 | *Method 1: Conventional method* 47 | 48 | ```php 49 | use zjkal\MysqlHelper; 50 | 51 | $mysql = new MysqlHelper('root', 'passwd', 'dbname', '127.0.0.1', '3306', 'utf8mb4', 'wp_'); 52 | ``` 53 | 54 | *Method 2: After instantiation, set the database configuration through the setConfig method* 55 | 56 | ```php 57 | $mysql = new MysqlHelper(); 58 | $mysql->setConfig(['username' => 'root', 'password' => 'passwd', 'database' => 'dbname']); 59 | ``` 60 | 61 | MysqlHelper is compatible with commonly used frameworks, you can directly use the database configuration of the framework, such as `ThinkPHP` framework or `Laravel` framework 62 | 63 | ```php 64 | $mysql = new MysqlHelper(); 65 | $config = config('database.connections.mysql'); 66 | $mysql->setConfig($config); 67 | ``` 68 | 69 | ### 2. export 70 | 71 | ```php 72 | //Export database (including table structure and data) 73 | $mysql->exportSqlFile('test.sql'); 74 | 75 | //Export only the database table structure 76 | $mysql->exportSqlFile('test.sql', false); 77 | 78 | //Export the structure and data of the specified table 79 | $mysql->exportSqlFile('test.sql', true, ['table1', 'table2']); 80 | 81 | //Export all tables in the database and add an SQL statement that disables foreign key checking 82 | $mysql->exportSqlFile('test.sql', true, [], true); 83 | //PHP8 or above can be written more concisely: 84 | $mysql->exportSqlFile('test.sql', disableForeignKeyChecks: true); 85 | ``` 86 | 87 | ### 3. Import 88 | 89 | * If you need to customize the table prefix during the import process, the table prefix in the SQL file needs to be replaced with a '__PREFIX__' placeholder 90 | * If the database prefix has been set during instantiation, you do not need to pass in the second parameter 91 | 92 | ```php 93 | import database 94 | $mysql->importSqlFile('test.sql'); 95 | 96 | //Import the database and automatically replace the table prefix 97 | $mysql->importSqlFile('test.sql', 'wp_'); 98 | 99 | //Import the database, do not replace the prefix, and delete the table first if it already exists 100 | $mysql->importSqlFile('test.sql', '', true); 101 | //PHP8 or above can be written more concisely: 102 | $mysql->importSqlFile('test.sql', dropTableIfExists: true); 103 | ``` 104 | 105 | ## 📃Changelog 106 | 107 | > v1.0.9 December 5, 2024 108 | > * Added parameters for data import to set whether to delete existing tables 109 | 110 | > v1.0.8 November 23, 2024 111 | > * Fixed the bug that the ignore statement was repeatedly replaced when importing a table 112 | 113 | > v1.0.7 Oct 4, 2024 114 | > * Improved the stability of imports: filter blank rows 115 | 116 | > v1.0.6 Aug 27, 2024 117 | > * Added logic to determine whether a table with the same name exists 118 | 119 | > v1.0.5 June 14, 2024 120 | > * Added the ability to set a parameter to disable foreign key checking during export 121 | 122 |
点击查看更多 123 | 124 | > v1.0.4 Apr 19, 2024 125 | > * Optimized the filtering rules for comments in .sql files 126 | 127 | > v1.0.3 Dec 9, 2023 128 | > * If a table prefix is set during instantiation, the exported table name can not contain the prefix 129 | 130 | > v1.0.2 Sep 23, 2023 131 | > * Increased export stability 132 | 133 | > v1.0.1 Sep 10, 2023 134 | > * Fixed the bug of incorrect port recognition under the Thinkphp framework 135 | > * Increased import stability 136 | 137 | > v1.0.0 Sep 2, 2023 138 | > * Initial Release 139 |
