convert array to string and get it back to array in PHP

Question

I\'m using the Serialize function to store an array in my MYSQL database, and then I\'m unSerialize Him in other page. The array structure look like this :

Array         


        

Answer 1

The opposite of serialize is unserialize.

$old_array = unserialize($serialized_array_string_from_db);

Storing values serialized into the database, disallows to query them individually. You have to fetch the serialized value, unserialize and then you can start working with them. This is not very efficient from a database design perspective. My suggestion is to create individual fields for "names" and "rating" in a extra table.

Store Array serialized to Database

$array = array('names' => 'somename1', 'rating' => 10);
$array_serialized_to_string = serialize($array);
doStoreToDb($array_serialized_to_string, somewhere);

Fetch Serialized Array from Database

$array_serialized_to_string = doFetchFromDb(somewhere);
$array = unserialize($array_serialized_to_string);

The difference in array structure might be the result from querying "the return set as array". Just remove the outer array:

$old_array = unserialize($serialized_array_string_from_db);
$array = $old_array[0];
