PHP is a popular web programming language for building web applications. Here are some examples and code snippets to build an app using PHP:
1. Authentication app: An authentication app that allows users to sign up, log in, and log out. This app could be built using PHP's built-in session handling functions. The package library that could be used for this could be secure_session.
2. Simple CRUD app: A simple CRUD app that allows users to create, read, update, and delete records from a database. This could be built using PHP and MySQL. The package library that could be used for this could be PDO.
Example code:
$db = new PDO('mysql:host=localhost;dbname=testdb;charset=utf8','username','password');
//create a new record $stmt = $db->prepare("INSERT INTO users (name, email) VALUES (?, ?)"); $stmt->execute(array('John Doe', 'john@example.com'));
//read a record $stmt = $db->query("SELECT * FROM users WHERE id = 1"); $user = $stmt->fetch(PDO::FETCH_ASSOC); echo $user['name'];
//update a record $stmt = $db->prepare("UPDATE users SET email = ? WHERE id = ?"); $stmt->execute(array('jane@example.com', 2));
//delete a record $stmt = $db->prepare("DELETE FROM users WHERE id = ?"); $stmt->execute(array(3)); ?>
3. API app: An API app that allows users to retrieve data from a database through RESTful API calls. This could be built using PHP and the Slim framework. The package library that could be used for this could be slim/slim.
Example code:
require 'vendor/autoload.php';
$app = new \Slim\App;
//get a user by ID $app->get('/users/{id}', function ($request, $response, $args) { $db = new PDO('mysql:host=localhost;dbname=testdb;charset=utf8', 'username', 'password'); $stmt = $db->prepare("SELECT * FROM users WHERE id = ?"); $stmt->execute(array($args['id'])); $user = $stmt->fetch(PDO::FETCH_ASSOC); return $response->withJson($user); });
//create a new user $app->post('/users', function ($request, $response, $args) { $db = new PDO('mysql:host=localhost;dbname=testdb;charset=utf8', 'username', 'password'); $stmt = $db->prepare("INSERT INTO users (name, email) VALUES (?, ?)"); $stmt->execute(array($request->getParam('name'), $request->getParam('email'))); return $response->withStatus(201); });
$app->run(); ?>
