<?php
// Code snippet for creating a simple file manager in PHP

// Check if the user is logged in
session_start();
if (!isset($_SESSION['username'])) {
    header('Location: login.php');
    exit();
}

// Display files in a directory
$dir = 'uploads/';
$files = scandir($dir);
foreach ($files as $file) {
    if ($file != '.' && $file != '..') {
        echo '<a href="' . $dir . $file . '">' . $file . '</a><br>';
    }
}

// Upload a file
if (isset($_POST['submit'])) {
    $target_dir = 'uploads/';
    $target_file = $target_dir . basename($_FILES['fileToUpload']['name']);
    if (move_uploaded_file($_FILES['fileToUpload']['tmp_name'], $target_file)) {
        echo 'File uploaded successfully';
    } else {
        echo 'Error uploading file';
    }
}
