What security risks are associated with using WHERE clauses in INSERT INTO statements in PHP?

Using WHERE clauses in INSERT INTO statements in PHP can pose a security risk as it can potentially lead to SQL injection attacks if the input is not properly sanitized. To mitigate this risk, it is important to use prepared statements with parameterized queries to prevent malicious code from being injected into the SQL query. 

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

// Prepare a SQL query using a parameterized query to safely insert data
$stmt = $pdo->prepare("INSERT INTO mytable (column1, column2) VALUES (:value1, :value2)");

// Bind the parameters with the actual values
$stmt->bindParam(':value1', $value1);
$stmt->bindParam(':value2', $value2);

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