What potential pitfalls should be considered when using array_filter() and min() together in PHP?

When using array_filter() and min() together in PHP, one potential pitfall to consider is that if the filtered array is empty, the min() function will return NULL instead of the expected minimum value. To solve this issue, you can check if the filtered array is empty before calling the min() function and handle this case accordingly.

// Example code snippet to avoid pitfalls when using array_filter() and min() together
$array = [4, 2, 7, 1, 5];
$filteredArray = array_filter($array, function($value) {
    return $value % 2 == 0; // Filter even numbers
});

if (!empty($filteredArray)) {
    $minValue = min($filteredArray);
    echo "Minimum value of filtered array: $minValue";
} else {
    echo "Filtered array is empty";
}
