Question

如何使用php从服务器导出和导入mysql数据库？

Answer 1

对于导出和导入我使用SSH命令，它非常快。

对于出口DATABSE：

$db_host = '15.2.4.222’;     // database server 
$db_user = 'db_user';     // database user name 
$db_pwd = 'dbpasword';    // database password 
$db_schema = 'db_name';   // name of database to be exported 

    exec(sprintf(
    'mysqldump --opt -h%s -u%s -p%s %s | gzip > /var/www/vhosts/yoursitename.com/httpdocs/ backups_db/backup_filename_%s.sql.gz', 
    $db_host, 
    $db_user, 
    $db_pwd, 
    $db_schema, 
    $today 
    )); 
    exit; 

现在对于进口：

$db_host = '15.2.4.222’;     // database server 
$db_user = 'db_user';     // database user name 
$db_pwd = 'dbpasword';    // database password 
$db_schema = 'db_name';   // name of database to be exported 

// Command to restore database  
exec("mysql -h [db server ip here] -u [db username here] –p[password here] [db name here] < /var/www/vhosts/yoursite.com/httpdocs/foldername_wherefile_exist/filename.sql"); 
// Example: 
exec("mysql -h 15.2.4.222 -u db_username -ptestpassword test_db_name < /var/www/vhosts/phproots.com/httpdocs/backups_db/filename.sql"); 

请使用它进行备份和恢复DATABSE。
