(範例 10) MySQL-PHP-RADIO-新增-查詢-刪除-更新範例(範例 10) MySQL-PHP-RADIO-新增-查詢-刪除-更新範例壹、新建資料庫、資料表 DROP DATABASE IF EXISTS mydb; CREATE DATABASE mydb DEFAULT CHARACTER SET utf8; USE mydb; CREATE TABLE stmd ( oid INT UNSIGNED NOT NULL AUTO_INCREMENT COMMENT '遞增識別碼', depart_class VARCHAR(16) COMMENT '甲班、乙班、丙班、丁班', student_no VARCHAR(16) COMMENT '1號、2號、3號、4號', student_name VARCHAR(16) COMMENT '陳生、林生、張生、謝生', address VARCHAR(16) COMMENT '台北、新北、台中、高雄', primary key(oid) ); 溫馨提醒:您的 config.php 正確嗎? 貳、撰寫 php <?php // sample10-radio.php include "config.php"; if (isset($_POST["command"])) $command=$_POST["command"]; else $command=""; if ($command=="" || $command=="返回") { display_first_page($conn);
