How to install Phalcon php - php

Question

I downloaded Phalcon from official website
I copied php_phalcon.dll file to my xampp's php/ext directory
Edited the php.ini file located at D:\xampp\php\php.ini. and add there line extension=php_phalcon.dll at the end of the file.
I Restarted apache server and computer several times.
When I write phpinfo() to my code it seems phalcon was installed
Unfortunatelly Whan I try to run some code like
<?php
try {
// Autoloader
$loader = new \Phalcon\Loader();
$loader->registerDirs([
'../app/controllers/',
'../app/models/'
]);
$loader->register();
// Dependency Injection
$di = new \Phalcon\DI\FactoryDefault();
$di->set('view', function() {
$view = new \Phalcon\Mvc\View();
$view->setViewsDir('../app/views');
return $view;
});
// Deploy the App
$app = new \Phalcon\Mvc\Application($di);
echo $app->handle()->getContent();
} catch(\Phalcon\Exception $e) {
echo $e->getMessage();
}
?>
I get this error
Fatal error: Uncaught Error: Class 'Phalcon\Loader' not found in D:\xampp\htdocs\php-learning\public\index.php:4 Stack trace: #0 {main} thrown in D:\xampp\htdocs\php-learning\public\index.php on line 4
I also tried to follow the steps from tutorial on Phalcon ofical website where code looks somehow like this
<?php
use Phalcon\Di\FactoryDefault;
use Phalcon\Loader;
use Phalcon\Mvc\View;
use Phalcon\Mvc\Application;
use Phalcon\Url;
// Define some absolute path constants to aid in locating resources
define('BASE_PATH', dirname(__DIR__));
define('APP_PATH', BASE_PATH . '/app');
// Register an autoloader
$loader = new Loader();
$loader->registerDirs(
[
APP_PATH . '/controllers/',
APP_PATH . '/models/',
]
);
$loader->register();
$container = new FactoryDefault();
$container->set(
'view',
function () {
$view = new View();
$view->setViewsDir(APP_PATH . '/views/');
return $view;
}
);
$container->set(
'url',
function () {
$url = new Url();
$url->setBaseUri('/');
return $url;
}
);
$application = new Application($container);
try {
// Handle the request
$response = $application->handle(
$_SERVER["REQUEST_URI"]
);
$response->send();
} catch (\Exception $e) {
echo 'Exception: ', $e->getMessage();
}
But didn´t help. What I am doing wrong?

Answer 1

You have Phalcon installed successfully. However the namespace should be changed:
Moved Phalcon\Loader to Phalcon\Autoload\Loader #15797
please refer to the change log
