如何使用php
在mysql数据库中导入.sql文件我该怎么做才能帮我解决这个问题，谢谢
此代码显示此错误..
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
我正在使用此代码
<?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>';

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，祝你好运

Raj的答案很有用，但是（因为文件（$ filename）） 如果您的mysql-dump不适合内存，它将失败
如果您<共享托管 并且限制，例如30 MB和12s脚本运行时，您必须恢复x00MB mysql转储 ，你可以使用这个脚本：
它将遍历dumpfile查询以进行查询，如果脚本执行截止时间接近，它会将当前文件位置保存在tmp文件中，并且自动浏览器重新加载将一次又一次地继续此过程... 如果发生错误，重新加载将停止并显示错误...

您可以使用mysqli multi_query函数，如下所示：
$sql = file_get_contents('mysqldump.sql');
$mysqli = new mysqli("localhost", "root", "pass", "testdb");
if (mysqli_connect_errno()) { /* check connection */
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
/* execute multi query */
if ($mysqli->multi_query($sql)) {
echo "success";
} else {
echo "error";
}

Grain Script非常棒，可以节省我的一天。同时mysql被折旧，我用PDO重写了Grain回答。
$server = 'localhost';

/* PDO connection start */
$conn = new PDO("mysql:host=$server; dbname=$database", $username, $password);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$conn->exec("SET CHARACTER SET utf8");
/* PDO connection end */
// your config
$filename = 'yourFile.sql';
$maxRuntime = 8; // less then your max script execution limit
$deadline = time()+$maxRuntime;
$progressFilename = $filename.'_filepointer'; // tmp file for progress
$errorFilename = $filename.'_error'; // tmp file for erro
($fp = fopen($filename, 'r')) OR die('failed to open file:'.$filename);
// check for previous error

$filePosition = 0;
if( file_exists($progressFilename) ){
$filePosition = file_get_contents($progressFilename);
fseek($fp, $filePosition);

$queryCount = 0;
$query = '';
while( $deadline>time() AND ($line=fgets($fp, 1024000)) ){
if(substr($line,0,2)=='--' OR trim($line)=='' ){
