如何在单个表.sql文件中编写多个查询并使用PHP上传？

Question

所有我想要的是创建2个或更多的表使用tables.sql文件通过PHP。

<?php
require '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 create
if($mysqli->query('CREATE DATABASE IF NOT EXISTS '.DB_NAME.';') === TRUE){
  echo "Database successfully created.<br>";
}else{
  echo "Error: ".$mysqli->errno.", ".$mysqli->error."<br>";
}

// DB select
if($mysqli->select_db(DB_NAME) === TRUE){
  echo "Database successfully selected.<br>";
}else{
  echo "Error: ".$mysqli->errno.", ".$mysqli->error;
}

// Create tables
if($mysqli->query(file_get_contents('../sql/tables.sql')) === TRUE){
  echo "Tables successfully created.<br>";
}else{
  echo "Error: ".$mysqli->errno.", ".$mysqli->error."<br>";
}

$mysqli->close();
?>

DB_HOST、DB_USER、DB_PASSWORD、DB_NAME在配置中定义。php文件

PHP v7.4.7

CREATE 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这个tables.sql文件直接上传到MySQL服务器，它就会工作。

MySQL v8.0.20 MySQL Comunity服务器-GPL

错误：1064，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“如果不存在则创建表”状态（状态 varchar（100） 不为空，第 16 行的“IDt”附近使用的正确语法

MySQL::查询只接受单个查询https://www.php.net/manual/en/mysqli.query.php.

如果你想一次执行多个查询，你必须使用 mysqli：：multi_query https://www.php.net/manual/en/mysqli.multi-query.php。

示例:

$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) ""
