get_called_class vs get_class

string get_called_class ( void ) //  Gets the name of the class the static method is called in. 
string get_class ([ object $object = NULL ] ) // Gets the name of the class of the given object. 


-------- get_called_class
class foo {
    static public function test() {
        var_dump(get_called_class());
    }
}

class bar extends foo {
}

foo::test(); // string(3) "foo"
bar::test(); // string(3) "bar"

--------- get_class

• get_class($this)
• get_class($bar)

class foo {
    function name()
    {
        echo "My name is " , get_class($this) , "\n";
    }
}

$bar = new foo(); // create an object
echo "Its name is " , get_class($bar) , "\n"; // external call		// Its name is foo
$bar->name(); // internal call						// My name is foo

----------

abstract class bar {
    public function __construct()
    {
        var_dump(get_class($this));
        var_dump(get_class());
    }
}

class foo extends bar {
}

new foo;

string(3) "foo"
string(3) "bar"

Database configuration

Create the file src/settings.php inside your api folder and place the following code

        "db" => [
            "host" => "locahost",
            "dbname" => "your-database-name",
            "user" => "your-mysql-user",
            "pass" => "your-mysql-password"
        ],

Create the file src/dependencies.php inside your api folder and place the following code

$container['db'] = function ($c) {
    $settings = $c->get('settings')['db']; // From src/settings.php
    $pdo = new PDO("mysql:host=" . $settings['host'] . ";dbname=" . $settings['dbname'],
        $settings['user'], $settings['pass']);
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    $pdo->setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE, PDO::FETCH_ASSOC);
    return $pdo;
};

This is injecting the database object into container, and you can now access all users
** For creating the users table see Create users table post

require __DIR__ . '/vendor/autoload.php';
$app = new Slim\App;

$app->get('/', function ($request, $response) {
    return 'hello world';
});

 $app->post('/postit', function ($request, $response) {
     $input = $request->getParsedBody();
     return $this->response->withJson($input);
 });

 $app->get('/all', function ($request, $response, $args) {
 $sth = $this->db->prepare("SELECT * FROM users");
 $sth->execute();
 $users = $sth->fetchAll();
     return $this->response->withJson($users);
 });

$app->run();
