How to set the primary key of phpmyadmin to auto-increment

Optimizing database tables can improve performance. The specific steps are as follows: 1. Log in to phpMyAdmin and select the corresponding database; 2. Select the table to be optimized from the table list, usually a table with high-frequency insertion, update or delete operations; 3. Select "Optimizetable" in the "Withselected:" menu and confirm execution. During optimization, MySQL rebuilds the table to reduce disk I/O, update index statistics, and free up space occupied by deleted or modified data, but this operation temporarily locks the table and is recommended during low peak periods. Not all tables need to be optimized regularly. It is more appropriate to optimize frequently changed tables once a month, and other tables may depend on the situation.

Quick and Custom are two options for phpMyAdmin to export databases. Quick is suitable for fast backup or migration of data, exported in the default SQL format without additional settings; while Custom provides advanced control functions, supports selection of file formats, compression methods, data structures, etc., suitable for scenarios where specific configurations are required or are ready to be delivered to other systems.

The "Designer" feature of phpMyAdmin is a visualization tool that helps users understand and manage relationships between tables in MySQL or MariaDB databases. It graphically displays table structure, foreign key connections, supports custom tags and annotations, provides an intuitive database schema view, and allows users to interactively adjust layouts. To use this feature, make sure the database uses the InnoDB engine and has foreign key constraints defined, then you can enter the interface by selecting the database and clicking the "Designer" tab at the top. In order to effectively use Designer, you should ensure that foreign keys are correctly set, use drag and drop functions to optimize layout, save the current arrangement, and add comments to improve readability. This tool is debugging complex queries,

To disable specific features or tabs in phpMyAdmin, it can be done by modifying the configuration file. 1. Edit the config.inc.php file and use settings such as $cfg['ShowPhpInfo']=false; to hide the specified tag; 2. Restrict access based on user roles, control the visibility of functions by creating MySQL users with limited permissions and configuring parameters such as $cfg['AllowUserDropDatabase']=false; to control the visibility of functions; 3. Turn off unnecessary functions, such as setting $cfg['AllowArbitraryServer']=false; to disable any server input; 4. Optionally, hide with custom themes
