How can dynamic content from a PHP form be properly appended to an array for sorting and storage in a text file?

When dynamically generated content from a PHP form needs to be appended to an array for sorting and storage in a text file, you can achieve this by first retrieving the form data, then appending it to an existing array, sorting the array as needed, and finally storing the sorted array in a text file. This can be done by using PHP functions like array_push() to append data to the array and file_put_contents() to save the sorted array to a text file. 

<?php
// Retrieve form data
$newData = $_POST['form_field'];

// Load existing data from text file
$existingData = file_get_contents('data.txt');
$dataArray = explode("\n", $existingData);

// Append new data to existing array
$dataArray[] = $newData;

// Sort the array
sort($dataArray);

// Save sorted array back to text file
file_put_contents('data.txt', implode("\n", $dataArray));
?>
