What are the potential pitfalls of storing data from a database as a string and converting it to an array in PHP?

Storing data from a database as a string and converting it to an array in PHP can lead to potential data loss or corruption if the string is not formatted correctly. To avoid this issue, it's recommended to use a proper serialization method like JSON or serialize when storing arrays in a database. 

// Example of storing an array in a database using JSON serialization
$data = ['foo', 'bar', 'baz'];
$jsonData = json_encode($data);

// Store $jsonData in the database

// Example of retrieving the array from the database and converting it back to an array
// Retrieve $jsonData from the database
$data = json_decode($jsonData, true);
