\n\n\n\n7\ufe0f\u20e3 Use the New Driver in Code<\/h2>\n\n\n\n
After the extension loads, use Composer\u2019s library in your PHP code:<\/p>\n\n\n\n
composer require mongodb\/mongodb\n<\/code><\/pre>\n\n\n\nThen in register.php<\/code>:<\/p>\n\n\n\nrequire 'vendor\/autoload.php';\n\n$client = new MongoDB\\Client(\"mongodb:\/\/localhost:27017\");\n$db = $client->selectDatabase('yourdb');\n<\/code><\/pre>\n\n\n\n\nImportant:<\/strong>
Do not use the legacy MongoClient<\/code> or new Mongo()<\/code> syntax.
The current driver works with MongoDB\\Client<\/code> (from Composer) or MongoDB\\Driver\\Manager<\/code> (low-level).<\/p>\n<\/blockquote>\n\n\n\n
\n\n\n\n1\ufe0f\u20e3 register.php<\/code> (with session start)<\/h2>\n\n\n\nThis script registers the user and<\/strong> starts a session so you can store the username.<\/p>\n\n\n\n<?php\nsession_start(); \/\/ Start or resume the session\n\nif (isset($_POST['submit'])) {\n $username = trim($_POST['username']);\n $password = $_POST['password'];\n\n if ($username === '' || $password === '') {\n exit(\"Username and password required.\");\n }\n\n try {\n $m = new MongoDB\\Driver\\Manager('mongodb:\/\/localhost:27017');\n } catch (MongoDB\\Driver\\Exception\\Exception $e) {\n exit(\"MongoDB connection failed: \" . $e->getMessage());\n }\n\n \/\/ Optional: create collection if not exists\n $command = new MongoDB\\Driver\\Command([\"create\" => 'e1']);\n try {\n $m->executeCommand(\"login\", $command);\n } catch (MongoDB\\Driver\\Exception\\CommandException $e) {\n if ($e->getCode() != 48) { \/\/ 48 = namespace exists\n exit(\"Error creating collection: \" . $e->getMessage());\n }\n }\n\n \/\/ Insert new user\n $bulk = new MongoDB\\Driver\\BulkWrite;\n $bulk->insert([\n \"username\" => $username,\n \"password\" => password_hash($password, PASSWORD_BCRYPT)\n ]);\n\n try {\n $m->executeBulkWrite('login.e1', $bulk);\n\n \/\/ Store username in session\n $_SESSION['username'] = $username;\n\n header('Location: page2.php');\n exit;\n } catch (MongoDB\\Driver\\Exception\\BulkWriteException $e) {\n exit(\"Error inserting document: \" . $e->getMessage());\n }\n}\n?>\n<!DOCTYPE html>\n<html>\n<body>\n<center><h1>Registration Form<\/h1><\/center>\n<form action=\"\" method=\"post\">\n <label>Username :<\/label>\n <input type=\"text\" name=\"username\"><br>\n <label>Password :<\/label>\n <input type=\"password\" name=\"password\"><br><br>\n <input type=\"submit\" value=\"Register\" name=\"submit\">\n<\/form>\n<\/body>\n<\/html>\n<\/code><\/pre>\n\n\n\n
\n\n\n\n2\ufe0f\u20e3 page2.php<\/code> (protected page)<\/h2>\n\n\n\n<?php\nsession_start();\n\n\/\/ Check if user is logged in\nif (!isset($_SESSION['username'])) {\n header('Location: register.php'); \/\/ or a login page\n exit;\n}\n?>\n<!DOCTYPE html>\n<html>\n<body>\n<h1>Welcome, <?php echo htmlspecialchars($_SESSION['username']); ?>!<\/h1>\n<p>This is a protected page.<\/p>\n<a href=\"logout.php\">Logout<\/a>\n<\/body>\n<\/html>\n<\/code><\/pre>\n\n\n\n
\n\n\n\n3\ufe0f\u20e3 logout.php<\/code> (destroy session)<\/h2>\n\n\n\n<?php\nsession_start();\nsession_unset(); \/\/ remove all session variables\nsession_destroy(); \/\/ destroy the session\nheader('Location: register.php');\nexit;\n<\/code><\/pre>\n\n\n\n
\n\n\n\n How It Works<\/h3>\n\n\n\n\nsession_start()<\/code> must be the first line<\/strong> (before any output) on every page that uses sessions.<\/li>\n\n\n\n- After successful registration, we store
$_SESSION['username']<\/code>.<\/li>\n\n\n\n- Any protected page checks
isset($_SESSION['username'])<\/code>.<\/li>\n\n\n\n- Logging out simply calls
session_destroy()<\/code>.<\/li>\n<\/ul>\n\n\n\nWith these changes, your MongoDB-based registration now supports full PHP session management.<\/p>\n\n\n\n
