`id` int(11) NOT NULL AUTO_INCREMENT,
`content` text CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;- The PHP code file is saved in UTF-8 format: When saving a PHP file in the editor, the UTF-8 encoding format should be selected to ensure that Chinese characters are supported. The sample code is as follows:
<?php
header('Content-Type: text/html; charset=utf-8');

<!DOCTYPE html> <html> <head> <meta charset="utf-8"> </head> <body> <!-- 页面内容 --> </body> </html>
