执行sql查询PHP中不起作用，但在phpMyAdmin

Question

查询工作，我有我的数据库SQL访问文件，我想在php通过下面的代码

$query = file_get_contents('./sqlquery.txt'); 
print $query; 
$conn->query($query); 

运行它，但它返回此错误

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 'CREATE TABLE IF NOT EXISTS `ads` (`id` int(11) NOT NULL AUTO_INCREMENT, `ur' at line 2 

我将打印输出复制到phpmyadmin中，一切正常，这里有什么问题？

我的SQL查询的这个

你在这里执行多个查询

，它不会简单地工作，我敢肯定，在query功能（$conn->query($query);）你使用mysql_query()或mysqli_query()，但您需要做的是使用mysqli_multi_query()代替。必须在docx

$con = mysqli_connect($host, $user, $pass, $db) OR die(mysqli_error($con)); 
$query = file_get_contents('./sqlquery.txt'); 
mysqli_multi_query($con, $query); 
mysqli_close($con); 

希望看看这里，这将帮助你

注意：假设而在PHPMyAdmin执行的所有查询都工作正常。
