What are the potential security risks of storing binary data in a MySQL database using PHP?

Storing binary data in a MySQL database using PHP can pose security risks such as SQL injection attacks if the data is not properly sanitized. To mitigate this risk, it is important to use prepared statements with parameterized queries to prevent malicious input from being executed as SQL commands. 

// Connect to MySQL database
$mysqli = new mysqli("localhost", "username", "password", "database");

// Prepare SQL statement with parameterized query
$stmt = $mysqli->prepare("INSERT INTO table_name (binary_data_column) VALUES (?)");
$stmt->bind_param("s", $binary_data);

// Set binary data variable
$binary_data = file_get_contents("file_path");

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

// Close statement and connection
$stmt->close();
$mysqli->close();
