Example:

$sth->bindValue(':calories', $calories, PDO::PARAM_INT);

PDO::PARAM_INT Is this parameter a kind of validation for data type? If so, why not give me an error when I pass an integer?

Just like @Oeslei said, PDO :: PARAM_INT (or STR), does not validate the type of value.

To do this in case you should use filter_var , for example:

if (filter_var($suaVariavel, FILTER_VALIDATE_INT)) {
    // válido
} else {
    // inválido
}
