How can PHP ensure that numeric values retrieved from a database are interpreted correctly without requiring type conversion?

When retrieving numeric values from a database in PHP, it's important to ensure that they are interpreted correctly without requiring type conversion. One way to achieve this is by using the PDO extension with prepared statements, which automatically binds parameters with the correct data types.

// Create a PDO connection to the database
$pdo = new PDO("mysql:host=localhost;dbname=my_database", "username", "password");

// Prepare a SQL statement with a placeholder for the numeric value
$stmt = $pdo->prepare("SELECT * FROM my_table WHERE numeric_column = :numeric_value");

// Bind the numeric value with the correct data type
$stmt->bindParam(':numeric_value', $numeric_value, PDO::PARAM_INT);

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

// Fetch the results
$results = $stmt->fetchAll();
