Saving mysql data in binary

Question

Is there a way I could retrieve data from a mysql db table and save them in a binary file?

My table looks like this

id  domain_name  isAuth
1   www.yah.com  1
2   www.go.com   0
3   www.goo.com  1
4   www.foo.com  1

Answer 1

Since performance seems to be the issue here, assuming $data is the result of a call to PDOStatement::fetchAll or mysqli_fetch_all , I suggest serialize and unserialize :

/* fetch $data */
file_put_contents('my_file.dat', serialize($data));
/* do some other stuff */
$data = unserialize(file_get_contents('my_file.dat'));
/* use $data */
