Question

我使用以下脚本：

<?php

ini_set('max_execution_time', 0);

ini_set('error_reporting', E_ALL);

$file = file_get_contents('./dump.sql');

//var_dump($file); die();

$conn = new mysqli('localhost', 'myUserName', 'myPassWord', 'myDataBase');

if (mysqli_connect_error()) {
    die('Connect Error (' . mysqli_connect_errno() . ') '
            . mysqli_connect_error());
}

echo 'Success... ' . $conn->host_info . "<br />";
echo 'Retrieving dumpfile' . "<br />";

$sql = $file;
if (!$sql){
    die ('Error opening file');
}

echo 'processing file <br />';
mysqli_multi_query($conn,$sql);

echo 'done.';
$conn->close();

?>

它输出以下内容，所有内容似乎都很顺利，完全没有错误：

Success... localhost via TCP/IP
Retrieving dumpfile
processing file
done.

但是，我的数据库中没有字段。什么都没有添加。

我的dump.sql文件中的第一行代码如下：

/*!40101 SET NAMES utf8 */;

INSERT INTO `content_field_image_cache` (`vid`, `nid`, `delta`, `field_image_cache_fid`, `field_image_cache_list`, `field_image_cache_data`) VALUES
(1000, 1000, 0, 1000, 1, NULL),
(1001, 1001, 0, 1001, 1, NULL),
(1002, 1002, 0, 1002, 1, NULL),
(1003, 1003, 0, 1003, 1, NULL),

为什么这段代码不起作用？感谢。

Answer 1

似乎您需要遍历结果以消除MySQL server has gone away.错误：

以最简单的形式（未经测试的例子）：

mysqli_multi_query($conn,$sql);

// You can do something with the results as well...
while (mysqli_use_result($conn) && mysqli_next_result($conn));

echo 'done.';
$conn->close();

尝试用分号“;”结束插入而不是你的最后一个元组之后的逗号。

MySQL多查询将无法正常工作
