exec('mysqldump --user=$user --password=$password --host=$host --database=$dbName > $dumpFilepath');

Replace the variables with appropriate values.

2. You can choose to download the dump directly to the client by replacing ">" with ":":

exec('mysqldump --user=$user --password=$password --host=$host --database=$dbName ');
