Backup and Restore MySQL database in PHP
提问by DeLe
I am trying to use PHP to backup and restore a MySQL database:
我正在尝试使用 PHP 来备份和恢复 MySQL 数据库：
Backup:
备份：
$dbhost = 'localhost';
$dbuser = 'root';
$dbpass = 'dbpass';
$dbname = 'test';
$output = "D:/backup/test.sql";
exec("D:/xampp/mysql/bin/mysqldump --opt -h $dbhost -u $dbuser -p $dbpass $dbname > $output");
echo "Backup complete!";
Restore:
恢复：
$dbhost = 'localhost';
$dbuser = 'root';
$dbpass = 'dbpass';
$dbname = 'test';
$output = "D:/restore/test.sql";
exec("D:/xampp/mysql/bin/mysql --opt -h $dbhost -u $dbuser -p $dbpass $dbname < $output");
echo "Restore complete!";
But both are not working. When Backup is complete then I check test.sqlfile that is blank. When the restore is complete, the database is still blank.
但两者都不起作用。备份完成后，我检查test.sql空白的文件。还原完成后，数据库仍为空白。
How can I fix this?
我怎样才能解决这个问题？
