phpmyadmin default import database file size is 2M, but the files exported by the database of general websites will exceed this limit. To import database files exceeding 2M, you need to manually modify the php.ini configuration file !
Recommended: phpmyadmin introductory tutorial
Modify in the php.ini file:
upload_max_filesize 20m (that is, the maximum size of the uploaded file allowed, the default is 2M, the modified value size is customized)
After modification, refresh the phpmyadin import database page and you will find that the import database size limit will be displayed as "(maximum limit: 8,192 KB)" instead of the manually set 20m .
Yes, if you only change the upload_max_filesize setting, the php.ini configuration will use the post_max_size configuration by default as the standard for the size limit of the database file imported by phpmyamdin.
So we still need to make the following modifications:
post_max_size 30m (referring to the maximum value that can be received through POST to PHP through the form, including all values in the form, the default is 8M)
Refresh the phpmyadin import database page again and you will find that the maximum limit value will become 20m, even if the upload_max_filesize configuration option is used. After modifying the above two values many times, we came to the conclusion:
php.ini will take the smaller value of the two configurations upload_max_filesize and post_max_size as the effective value for the import database file size limit! !
Note: For the above settings to take effect, you must confirm:
file_uploads on

phpMyAdmin is a web-based MySQL database management tool that allows users to manage databases through a graphical user interface (GUI). 1. It interacts with the MySQL database through PHP scripts, converts user operations into SQL queries and renders the results. 2. Basic usage includes creating databases and tables, such as creating databases named 'my_database' and 'users' tables. 3. Advanced usage supports complex queries and user permission management, such as finding users with specific user names. 4. Common error debugging techniques include checking SQL syntax, managing permissions, and viewing logs. 5. Performance optimization suggestions include index optimization, query optimization and ensuring security.

phpMyAdmin simplifies SQL operations through a graphical interface and improves database management efficiency. 1) Provide an intuitive GUI without directly writing SQL statements; 2) Interact with MySQL through PHP scripts to transparently handle complex operations; 3) Support basic operations such as creating tables and advanced functions such as data export. Pay attention to permissions and SQL syntax errors when using it, and optimize queries, regular backups and ensure security settings.

Beginners can learn SQL and phpMyAdmin from scratch. 1) Create database and tables: Create a new database in phpMyAdmin and create tables using SQL commands. 2) Execute basic query: Use SELECT statement to query data from the table. 3) Optimization and best practices: Create indexes, avoid SELECT*, use transactions, and regularly back up databases.

MySQL and phpMyAdmin are powerful database management tools. 1.MySQL is an open source relational database management system, and phpMyAdmin is a MySQL management tool based on the Web. 2.MySQL works through the client-server model, and phpMyAdmin simplifies database operations. 3. Basic usage includes creating tables and data operations, and advanced usage involves stored procedures and triggers. 4. Common errors include SQL syntax errors, permission issues and performance bottlenecks. 5. Optimization techniques include reasonable use of indexes, optimized query, regular maintenance and backup and recovery.

phpMyAdmin implements the operation of the database through SQL commands. 1) phpMyAdmin communicates with the database server through PHP scripts, generates and executes SQL commands. 2) Users can enter SQL commands in the SQL editor for query and complex operations. 3) Performance optimization suggestions include optimizing SQL queries, creating indexes and using pagination. 4) Best practices include regular backups, ensuring security and using version control.

phpMyAdmin improves database productivity through an intuitive web interface: 1. Simplify the creation and management of databases and tables; 2. Support complex SQL queries and data operations; 3. Provide relationship view functions to manage table relationships; 4. Optimize performance and best practices to improve efficiency.

phpMyAdmin is a web-based MySQL database management tool. 1. It supports basic CRUD operations and advanced features such as database design and performance optimization. 2. Run through the web server, accept user input and convert it to MySQL commands. 3. The basic usage includes creating a database, and the advanced usage supports query optimization. 4. Common errors such as insufficient permissions can be solved by checking user permissions. 5. Performance optimization includes index optimization, query optimization and database design.

The roles of MySQL and phpMyAdmin are to store and manage data and provide user-friendly database management interfaces. MySQL performs data operations through SQL, phpMyAdmin interacts with MySQL through HTTP requests, and converts user operations into SQL commands.
