What are some potential pitfalls of storing complex arrays in a database using base64 encoding in PHP?

Storing complex arrays in a database using base64 encoding in PHP can make it difficult to query and manipulate the data directly in the database. It can also lead to increased storage size and slower retrieval times. To solve this issue, consider serializing the array before encoding it in base64, or storing the array data in a separate table with a proper schema. 

// Serialize the array before base64 encoding
$data = serialize($complexArray);
$encodedData = base64_encode($data);

// To store in the database
// INSERT INTO table_name (encoded_data) VALUES ('$encodedData');

// To retrieve and decode the data
// $result = SELECT encoded_data FROM table_name;
// $decodedData = unserialize(base64_decode($result['encoded_data']));
