In what scenarios or applications would it be recommended to avoid using addslashes() in PHP for handling JSON data in database backups?

When handling JSON data in database backups, it is recommended to avoid using addslashes() in PHP as it can add unnecessary escape characters to the JSON data, potentially corrupting the structure and causing issues when restoring the data. Instead, it is better to use prepared statements or parameterized queries to safely insert the JSON data into the database without the need for escaping characters. 

// Example of using prepared statements to insert JSON data into a database without addslashes()

// Assuming $json_data contains the JSON data to be inserted into the database
$json_data = '{"name": "John Doe", "age": 30}';

// Prepare the SQL statement with a placeholder for the JSON data
$stmt = $pdo->prepare("INSERT INTO table_name (json_column) VALUES (:json_data)");

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

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