What are the potential pitfalls of using serialize to store data in a relational database in PHP?

Using serialize to store data in a relational database in PHP can lead to issues with data retrieval and manipulation. It can make querying and updating specific fields within the serialized data difficult. Additionally, it can impact the performance of the database as serialized data cannot be indexed efficiently. To solve this issue, it is recommended to normalize the data by storing it in separate columns within the database table. 

// Instead of serializing data, store it in separate columns
$data = ['key1' => 'value1', 'key2' => 'value2'];

// Insert data into the database
$stmt = $pdo->prepare("INSERT INTO table_name (column1, column2) VALUES (:value1, :value2)");
$stmt->bindParam(':value1', $data['key1']);
$stmt->bindParam(':value2', $data['key2']);
$stmt->execute();
