How can the PHP function is_float() be utilized to check for decimal places in numbers?

To check for decimal places in numbers using the `is_float()` PHP function, you can pass the number as an argument to the function. If the number is a float (i.e., it has decimal places), the function will return true; otherwise, it will return false. This can be useful for validating user input or performing calculations that require decimal precision. 

$number = 10.5;

if (is_float($number)) {
    echo "The number has decimal places.";
} else {
    echo "The number does not have decimal places.";
}
