What are some potential pitfalls to watch out for when using the "NOT IN" clause in a MySQL query within a PHP script?
When using the "NOT IN" clause in a MySQL query within a PHP script, be cautious of potential pitfalls such as SQL injection attacks. To prevent this, it is recommended to use prepared statements with parameterized queries to sanitize user input and avoid any malicious code execution.
// Using prepared statements to avoid SQL injection
$stmt = $pdo->prepare("SELECT * FROM table_name WHERE column_name NOT IN (:value)");
$stmt->bindParam(':value', $value);
$stmt->execute();
