In PHP, what considerations should be taken into account when dealing with different data types in database queries, such as strings and numbers?

When dealing with different data types in database queries in PHP, it is important to ensure that the data being passed to the query is properly formatted based on the data types expected by the database. This includes properly escaping strings to prevent SQL injection attacks and ensuring that numbers are formatted correctly. Using prepared statements can help in handling different data types safely and efficiently.

// Example of using prepared statements to handle different data types in a database query

// Assuming $db is a PDO object connected to the database

$name = "John Doe";
$age = 30;

$stmt = $db->prepare("INSERT INTO users (name, age) VALUES (:name, :age)");
$stmt->bindParam(':name', $name, PDO::PARAM_STR);
$stmt->bindParam(':age', $age, PDO::PARAM_INT);
$stmt->execute();
