What potential pitfalls can occur when trying to obtain integer results in PHP division operations?

When performing division operations in PHP, the result may not always be an integer due to the way PHP handles division with integers. To ensure that the result is an integer, you can use the `intval()` function to convert the result to an integer.

$numerator = 10;
$denominator = 3;

$result = intval($numerator / $denominator);

echo $result; // Output: 3
