Question

How can I add a value into an array in a database row, and then later on, when I want to get values of the array, simply display each different array value on a new line?

Also, how do arrays work in mysql and how to get the value of it?

Answer 1

Filed testField has serialized data.

$arrayData = array('one','two','three');
$serializedData = serialize($arrayData);

Mysql insertion:

insert INTO table ('testField') Values ($serializedData);

To get data:

select testField from table where id=1

You are getting here some string value. Then you should unserialize this string to get array:

$arrayData = unserialize($selectResultValue);

Look here for more details about serialize function:
