What are the potential pitfalls of storing JSON data in text fields in a database?

Storing JSON data in text fields in a database can make it difficult to query and manipulate the data efficiently. It can also lead to potential data integrity issues if the JSON structure is not properly validated before insertion. To solve this issue, consider using a dedicated JSON data type provided by some databases or storing the JSON data in a separate table with a more structured schema. 

// Example of storing JSON data in a separate table with a structured schema
// Assuming $jsonData contains the JSON data to be stored

// Connect to the database
$pdo = new PDO('mysql:host=localhost;dbname=your_database', 'username', 'password');

// Prepare the SQL statement
$stmt = $pdo->prepare("INSERT INTO json_data_table (json_data) VALUES (:json_data)");

// Bind the JSON data parameter
$stmt->bindParam(':json_data', $jsonData, PDO::PARAM_STR);

// Execute the statement
$stmt->execute();
