How can PHP developers implement a pagination feature in a script that reads data from separate files without relying on a MySQL database for managing content?

To implement pagination in a PHP script that reads data from separate files without using a MySQL database, developers can utilize file handling functions to read and display the content in chunks. By keeping track of the current page and the number of items per page, developers can calculate the offset and limit for each page. Then, they can display the content accordingly using PHP. 

<?php
$itemsPerPage = 10;
$currentpage = isset($_GET['page']) ? $_GET['page'] : 1;
$offset = ($currentpage - 1) * $itemsPerPage;

$files = glob('data/*.txt');
$totalItems = count($files);

$filesToDisplay = array_slice($files, $offset, $itemsPerPage);

foreach ($filesToDisplay as $file) {
    $content = file_get_contents($file);
    echo $content . "<br>";
}

for ($i = 1; $i <= ceil($totalItems / $itemsPerPage); $i++) {
    echo "<a href='?page=$i'>$i</a> ";
}
?>
