What are the potential security risks associated with directly inserting JSON data into SQL queries in PHP and how can they be mitigated?

Directly inserting JSON data into SQL queries in PHP can lead to SQL injection attacks, as malicious users can manipulate the JSON data to inject harmful SQL code. To mitigate this risk, it is recommended to use prepared statements with parameterized queries to properly sanitize and escape the JSON data before inserting it into the database. 

// Assuming $jsonData contains the JSON data to be inserted into the database

// Establish a database connection
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");

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

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

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