What are common pitfalls when dealing with numeric values in PHP SQL queries?

One common pitfall when dealing with numeric values in PHP SQL queries is forgetting to properly sanitize the input, which can lead to SQL injection attacks. To solve this issue, always use prepared statements with placeholders when executing SQL queries with numeric values. 

// Using prepared statements to safely handle numeric values in SQL queries
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");

// Example query with a numeric value
$value = 123;
$stmt = $pdo->prepare("SELECT * FROM mytable WHERE column = :value");
$stmt->bindParam(':value', $value, PDO::PARAM_INT);
$stmt->execute();

// Fetching results
$results = $stmt->fetchAll(PDO::FETCH_ASSOC);
