What are some common pitfalls to avoid when sorting and displaying data in PHP using for loops and array functions?

One common pitfall to avoid when sorting and displaying data in PHP using for loops and array functions 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 solve this, always check if the array is empty before sorting or displaying its contents. 

// Check if the array is empty before sorting and displaying data
if (!empty($data)) {
    // Sort the array
    sort($data);
    
    // Display the sorted data
    foreach ($data as $value) {
        echo $value . "<br>";
    }
} else {
    echo "No data to display.";
}
