如何在单个tables.sql文件中编写多个查询并使用PHP上传？

Question

我想要的只是通过 PHP 使用文件创建 2 个或更多表tables.sql。PHPcreate_db.php<?phprequire 'config.php';$mysqli = new mysqli(DB_HOST, DB_USER, DB_PASSWORD);/* check connection */if($mysqli->connect_errno){  echo "MySQL connection failed.<br>";  exit();}else{  echo "MySQL successfully connected.<br>";}// DB createif($mysqli->query('CREATE DATABASE IF NOT EXISTS '.DB_NAME.';') === TRUE){  echo "Database successfully created.<br>";}else{  echo "Error: ".$mysqli->errno.", ".$mysqli->error."<br>";}// DB selectif($mysqli->select_db(DB_NAME) === TRUE){  echo "Database successfully selected.<br>";}else{  echo "Error: ".$mysqli->errno.", ".$mysqli->error;}// Create tablesif($mysqli->query(file_get_contents('../sql/tables.sql')) === TRUE){  echo "Tables successfully created.<br>";}else{  echo "Error: ".$mysqli->errno.", ".$mysqli->error."<br>";}$mysqli->close();?>DB_HOST、DB_USER、DB_PASSWORD、DB_NAME 在 config.php 文件中定义PHP v7.4.7SQLtables.sqlCREATE TABLE IF NOT EXISTS `users` (  `id` int(11) NOT NULL auto_increment,  `username` varchar(100) NOT NULL,  `password` varchar(100) NOT NULL,  PRIMARY KEY (`id`));CREATE TABLE IF NOT EXISTS `status` (  `status` varchar(100) NOT NULL,  `IDtime` varchar(100) NOT NULL);如果我使用命令行将此tables.sql 文件直接上传到MySQL 服务器，它就可以工作。MySQL v8.0.20 MySQL 社区服务器 - GPL错误信息错误：1064，您的 SQL 语法有错误；检查与您的 MySQL 服务器版本相对应的手册，了解在第 16 行的'CREATE TABLE IF NOT EXISTS status( varchar(100) NOT NULL, `IDt' 附近使用的正确语法status

例子：

$result = $mysqli->query("SELECT * FROM reservations;SELECT * FROM reservations");

var_dump($result, $mysqli->error);

bool(false)

string(172) "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SELECT * FROM reservations' at line 1"

$result = $mysqli->multi_query("SELECT * FROM reservations;SELECT * FROM reservations");

var_dump($result, $mysqli->error);

bool(true)

string(0) ""
