How to Paginate Content from a Text File Using PHP1200×630 153 KB

I’ve got a text file with multiple messages separated by <br/> tags. I need to split them into pages, like search results. So if I have 50 messages, show 10 per page. How can I do this in PHP without a database? The file is basically:

some message <br/>
some message <br/>
...

Any ideas? I’m trying to keep it simple and just use the file.

Topic Summary: Split a text file of messages separated by <br/> into pages with PHP. Read file, explode by <br/>, paginate array (e.g., 10 per page) using simple offset/limit logic. No database needed.

You can easily do this by reading the file into an array using file() or explode() on the <br/> delimiter. Then use array slicing with offset and limit based on the current page. Here’s a clean modern approach:

<?php
// Read file and split by <br/>
$content = file_get_contents('messages.txt');
$messages = explode('<br/>', $content);
$messages = array_filter($messages, 'trim'); // remove empty entries

// Pagination settings
$perPage = 10;
$page = isset($_GET['page']) ? max(1, (int)$_GET['page']) : 1;
$totalPages = ceil(count($messages) / $perPage);
$offset = ($page - 1) * $perPage;
$pageMessages = array_slice($messages, $offset, $perPage);

// Display messages
foreach ($pageMessages as $msg) {
    echo htmlspecialchars($msg) . '<br/>';
}

// Navigation links
echo '<div>';
if ($page > 1) {
    echo '<a href="?page=' . ($page - 1) . '">Previous</a> ';
}
for ($i = 1; $i <= $totalPages; $i++) {
    echo '<a href="?page=' . $i . '">' . $i . '</a> ';
}
if ($page < $totalPages) {
    echo '<a href="?page=' . ($page + 1) . '">Next</a>';
}
echo '</div>';
?>

No database needed. Works fine for small to medium files. If your file gets huge, consider splitting into multiple files or using a database. Also, make sure the file path is correct and the file is readable.

Roly’s solution is solid. Just a couple of additions:

  • If you’re dealing with WAP devices, keep the output minimal and avoid heavy HTML. Use plain text or lightweight markup.
  • For file-based pagination, consider caching the parsed array if the file doesn’t change often. You can serialize the array and store it as a cache file to avoid repeated explode.
  • If you ever move to a database, use PDO with prepared statements for security. Here’s a quick example of a modern database pagination approach:
<?php
$pdo = new PDO('mysql:host=localhost;dbname=mydb', 'user', 'pass');
$perPage = 10;
$page = isset($_GET['page']) ? max(1, (int)$_GET['page']) : 1;
$offset = ($page - 1) * $perPage;

$stmt = $pdo->prepare('SELECT * FROM messages ORDER BY id DESC LIMIT :limit OFFSET :offset');
$stmt->bindValue(':limit', $perPage, PDO::PARAM_INT);
$stmt->bindValue(':offset', $offset, PDO::PARAM_INT);
$stmt->execute();
$messages = $stmt->fetchAll(PDO::FETCH_ASSOC);

// Then display and add pagination links with total count
?>

But for your WAP text file, go with the first solution. Just test with a small file first. Good luck!
