问题
In my application, to move a file to a specific directory i need to know public folder path in controller action. I read different this type solution but not getting easy one. I know that in view we can get easily public folder path using $this->basePath(); view helper. I exactly want this in controller action. Anybody can guide me how can i achieve that. Thanks in advance.
回答1:
index.php sets the current working dir to you application root (the folder containing composer.json, init_autoloader.php, etc.)
As long as you haven't called chdir elsewhere in your application you can call getcwd() and it'll always return the path to your app root.
Since the public folder is relative to that, you can get the path using ...
$publicDir = getcwd() . '/public';
回答2:
In your public folder edit your file named index.php add only two lines
define('BASE_PATH', realpath(dirname(__DIR__)));
define('PUBLIC_PATH', BASE_PATH.'/public');
you can use in your code like
print_r(BASE_PATH);
print_r(PUBLIC_PATH);

You could use view helpers from within a controller in ZF2 as it shown here and here. You may try this for your case :
$renderer = $this->serviceLocator->get('Zend\View\Renderer\RendererInterface');
$url = $renderer->basePath('the_ressource_you_want_to_get_from_public_folder');
Hope this is what you're looking for !

If you want to include a file from public folder (independence with location of index.php file): include_one ("./public/your-file.php");
回答5:
You should try this if you want the public folder:
$publicPath = $_SERVER['DOCUMENT_ROOT'];
Or try this if you want the basepath:
$basePath = dirname($_SERVER['DOCUMENT_ROOT']);
