How can PHP developers automate the process of displaying data in "letter blocks" for easier navigation?

To automate the process of displaying data in "letter blocks" for easier navigation, PHP developers can create a function that generates the desired letter blocks based on the data provided. This function can take in the data to be displayed and the block size as parameters, then loop through the data and format it into letter blocks. By encapsulating this logic in a reusable function, developers can easily implement and customize the display of data in letter blocks. 

function displayLetterBlocks($data, $blockSize) {
    $letterBlocks = str_split($data, $blockSize);
    
    foreach($letterBlocks as $block) {
        echo "<div class='letter-block'>$block</div>";
    }
}

// Example usage
$data = "Lorem ipsum dolor sit amet, consectetur adipiscing elit.";
$blockSize = 5;
displayLetterBlocks($data, $blockSize);
