Sometime we need to store array to database then we need to retrieve and use as variable array. I used session variable to save data and used it later.

Its simple just use the following

#using serialize() method
$data = serialize($_SESSION);
$sql = "Insert into sessioninfo `data` values('$data')";

just run the above query and save the whole session data into a database table. You might be use any array here.

Now retrieve the data

# I assume you can retrieve the data from database and assign to the following variable
$data = unserialize($row['data']);

Now $data have the same value or nested array.

So just using serialize() and unserialize() we can do this.

Done !
