在.sql扩展中使用php代码导出数据库？ [重复]

Is it possible export database using php code in .sql Extension?

Example

database name : demodb

db contain two tables
table one : user
table two : registration

</div>

Yes Its possible .

 <?php
        //ENTER THE RELEVANT INFO BELOW
        $mysqlDatabaseName ='xxxxxx';
        $mysqlUserName ='xxxxxxx';
        $mysqlPassword ='myPassword';
        $mysqlHostName ='xxxxxxxx.net';
        $mysqlExportPath ='chooseFilenameForBackup.sql';

        //DO NOT EDIT BELOW THIS LINE
        //Export the database and output the status to the page
        $command='mysqldump --opt -h' .$mysqlHostName .' -u' .$mysqlUserName .' -p' .$mysqlPassword .' ' .$mysqlDatabaseName .' > ~/' .$mysqlExportPath;
        exec($command);
 ?>

use mysqldump command for mySql db:

$command = "/usr/bin/mysqldump -u mysql_username -h mysql_host -p mysql_password database_name> /path_to_export_location/file_name.sql";
exec($command, NULL, NULL);

make a look at documentation in MySQL
