In what scenarios would it not make sense to use unserialize() function in PHP, especially when dealing with Mediumtext data type in a database column?

When dealing with Mediumtext data type in a database column, it may not make sense to use the unserialize() function in PHP because Mediumtext data can store large amounts of text data, such as JSON or serialized data, which can potentially exceed the memory limit when unserialized. In such scenarios, it is better to directly fetch the data from the database and handle it accordingly without using unserialize().

// Fetch Mediumtext data from the database
$query = "SELECT mediumtext_column FROM your_table WHERE condition = ?";
$stmt = $pdo->prepare($query);
$stmt->execute([$condition]);
$data = $stmt->fetchColumn();

// Handle the data without using unserialize()
// For example, you can directly work with the JSON data
$jsonData = json_decode($data, true);

// Use the $jsonData array as needed
