php - define anonymous function using values from current scope? -

i trying create anonymous function need access variables current scope in it's definition:

class test { private $types = array('css' => array('folder' => 'css')); public function __construct(){ //define our asset types foreach($this->types $name => $attrs){ $this->{$name} = function($file = ''){ //this line falls over! //undefined variable $attrs! return '<link href="'.$attrs['folder'].'/'.$file.'" />'; } } } } $assets = new test(); 

obviously example very minimalistic gets across trying do. so, question is, how can access parent scope definition of function? (once defined don't need context when function called).

ok after using matthew's answer have added use below; issue when call function no output.

if add die('called') in function produced, not if echo or return something.

class test { private $types = array('css' => array('folder' => 'css')); public function __construct(){ //define our asset types foreach($this->types $name => $attrs){ $this->{$name} = function($file = '') use ($attrs){ //this line falls over! //undefined variable $attrs! return '<link href="'.$attrs['folder'].'/'.$file.'" />'; } } } public function __call($method, $args) { if (isset($this->$method) === true) { $func = $this->$method; //tried , without "return" return $func($args); } } } $assets = new test(); echo 'output: '.$assets->css('lol.css'); 

function($file = '') use ($attrs)
