What is the best practice for storing JSON strings in a PHP database?

When storing JSON strings in a PHP database, it is best practice to use the `json_encode()` function to convert the data into a JSON string before inserting it into the database. When retrieving the data from the database, use `json_decode()` to convert the JSON string back into a PHP array or object. 

// Encode the data into a JSON string before storing it in the database
$data = ['key1' => 'value1', 'key2' => 'value2'];
$jsonData = json_encode($data);

// Insert the JSON string into the database
$query = "INSERT INTO table_name (json_data) VALUES ('$jsonData')";
// Execute the query

// Retrieve the JSON string from the database
$query = "SELECT json_data FROM table_name WHERE id = 1";
// Execute the query
$row = // Fetch the row from the database

// Decode the JSON string back into a PHP array
$data = json_decode($row['json_data'], true);
