What are some best practices for handling data manipulation operations in PHP scripts?
When handling data manipulation operations in PHP scripts, it is important to sanitize user input to prevent SQL injection attacks and validate data to ensure its integrity. Additionally, using prepared statements with parameterized queries can help prevent SQL injection vulnerabilities.
// Sanitize user input
$user_input = $_POST['user_input'];
$sanitized_input = filter_var($user_input, FILTER_SANITIZE_STRING);
// Validate data
if (strlen($sanitized_input) > 0) {
// Perform data manipulation operations
}
// Prepared statement with parameterized query
$stmt = $pdo->prepare("INSERT INTO table_name (column_name) VALUES (:value)");
$stmt->bindParam(':value', $sanitized_input);
$stmt->execute();
