我正在尝试通过PHP代码导入.sql文件。但是，我的代码显示此错误：

There was an error during import. Please make sure the import file is saved in the same folder as this script and check your values:

MySQL Database Name:    test
MySQL User Name:    root
MySQL Password: NOTSHOWN
MySQL Host Name:    localhost
MySQL Import Filename:  dbbackupmember.sql

这是我的代码：

<?php
//ENTER THE RELEVANT INFO BELOW
$mysqlDatabaseName ='test';
$mysqlUserName ='root';
$mysqlPassword ='';
$mysqlHostName ='localhost';
$mysqlImportFilename ='dbbackupmember.sql';
//DONT EDIT BELOW THIS LINE
//Export the database and output the status to the page
$command='mysql -h' .$mysqlHostName .' -u' .$mysqlUserName .' -p' .$mysqlPassword .' ' .$mysqlDatabaseName .' < ' .$mysqlImportFilename;
exec($command,$output=array(),$worked);
switch($worked){
    case 0:
        echo 'Import file <b>' .$mysqlImportFilename .'</b> successfully imported to database <b>' .$mysqlDatabaseName .'</b>';
        break;
    case 1:
        echo 'There was an error during import. Please make sure the import file is saved in the same folder as this script and check your values:<br/><br/><table><tr><td>MySQL Database Name:</td><td><b>' .$mysqlDatabaseName .'</b></td></tr><tr><td>MySQL User Name:</td><td><b>' .$mysqlUserName .'</b></td></tr><tr><td>MySQL Password:</td><td><b>NOTSHOWN</b></td></tr><tr><td>MySQL Host Name:</td><td><b>' .$mysqlHostName .'</b></td></tr><tr><td>MySQL Import Filename:</td><td><b>' .$mysqlImportFilename .'</b></td></tr></table>';
        break;
}
?>

我做错了什么？SQL 文件位于同一目录中。

警告：扩展从 PHP 5.5.0 开始被弃用，并且从 PHP 7.0.0 开始被删除。相反，应该使用mysqli或PDO_MySQL扩展。另请参阅 MySQL API 概述，以获取有关选择 MySQL API 的进一步帮助。
只要有可能，将文件导入MySQL应委托给MySQL客户端。mysql_*

我有另一种方法可以做到这一点，试试这个

<?php

// Name of the file
$filename = 'churc.sql';
// MySQL host
$mysql_host = 'localhost';
// MySQL username
$mysql_username = 'root';
// MySQL password
$mysql_password = '';
// Database name
$mysql_database = 'dump';

// Connect to MySQL server
mysql_connect($mysql_host, $mysql_username, $mysql_password) or die('Error connecting to MySQL server: ' . mysql_error());
// Select database
mysql_select_db($mysql_database) or die('Error selecting MySQL database: ' . mysql_error());

// Temporary variable, used to store current query
$templine = '';
// Read in entire file
$lines = file($filename);
// Loop through each line
foreach ($lines as $line)
{
// Skip it if it's a comment
if (substr($line, 0, 2) == '--' || $line == '')
    continue;

// Add this line to the current segment
$templine .= $line;
// If it has a semicolon at the end, it's the end of the query
if (substr(trim($line), -1, 1) == ';')
{
    // Perform the query
    mysql_query($templine) or print('Error performing query \'<strong>' . $templine . '\': ' . mysql_error() . '<br /><br />');
    // Reset temp variable to empty
    $templine = '';
}
}
 echo "Tables imported successfully";
?>

这对我有用

您可以使用 mysqli multi_query 函数，如下所示：

$sql = file_get_contents('mysqldump.sql');

$mysqli = new mysqli("localhost", "root", "pass", "testdb");

/* execute multi query */
$mysqli->multi_query($sql);
