The datatype you’re showing us here is a serialized variable in PHP.
To serialize or unserialize it, just use these two methods :
http://php.net/manual/en/function.serialize.php
http://www.php.net/manual/en/function.unserialize.php
To store it in MySQL, depends on the size of the serialized data. VARCHAR, TINYTEXT, TEXT, MEDIUMTEXT or BIGTEXT are available.
