What are some best practices for sorting and displaying data from a CSV file in a PHP application?

When sorting and displaying data from a CSV file in a PHP application, it is important to read the CSV file, parse its contents, sort the data based on specific criteria, and then display the sorted data in a user-friendly format. One way to achieve this is by using the fgetcsv function to read the CSV file, storing the data in an array, sorting the array using PHP's array_multisort function, and then iterating over the sorted array to display the data. 

<?php

// Read the CSV file
$csvFile = 'data.csv';
$csvData = [];
if (($handle = fopen($csvFile, 'r')) !== false) {
    while (($data = fgetcsv($handle, 1000, ',')) !== false) {
        $csvData[] = $data;
    }
    fclose($handle);
}

// Sort the data based on a specific column (e.g., column index 0)
array_multisort(array_column($csvData, 0), SORT_ASC, $csvData);

// Display the sorted data
foreach ($csvData as $row) {
    echo implode(', ', $row) . '<br>';
}

?>
