How can the use of the return statement within functions improve the overall structure and efficiency of PHP scripts, especially in scenarios like color switching for table rows?

Using the return statement within functions can improve the overall structure and efficiency of PHP scripts by allowing the function to return a value or result back to the caller. In scenarios like color switching for table rows, a function can be created to determine the color based on certain conditions and return the color value. This helps in keeping the code organized, reusable, and easier to maintain. 

function getRowColor($rowNumber) {
    return $rowNumber % 2 == 0 ? 'lightgray' : 'white';
}

// Example usage
for ($i = 1; $i <= 10; $i++) {
    $color = getRowColor($i);
    echo "<tr style='background-color: $color;'><td>Row $i</td></tr>";
}
