When using the array_column function in PHP version 5.5 and above, one potential pitfall to be aware of is that it will throw a warning if the input array is empty. To solve this issue, you can check if the input array is empty before calling array_column. 

// Check if the input array is empty before using array_column

    $result = array_column($inputArray, 'column_key');
    // Rest of your code here
} else {
    // Handle the case when the input array is empty
}
