What potential pitfalls should be considered when using array functions in PHP?

One potential pitfall when using array functions in PHP is not checking if the array is empty before performing operations on it. This can lead to errors or unexpected behavior if the array is empty. To avoid this, always check if the array is empty before using array functions. 

// Check if the array is empty before using array functions
if (!empty($myArray)) {
    // Perform array functions on $myArray
    $filteredArray = array_filter($myArray, function($value) {
        return $value > 5;
    });
} else {
    // Handle case where $myArray is empty
    echo "Array is empty";
}
