php - Array passed into class constructor is empty - Cannot access empty property -

i trying pass in array new class have access variable.

to this:

class appointmentdata {    private $date = [];    public function __construct(array $date)   {     $this->date = $date;   }    public function foo()   {     dd($this->$date);   }  } 

then:

$appointmentdata = new appointmentdata($date); 

however when calling function controller error:

cannot access empty property 

am doing correctly in assigning variable in constructor etc?

your issue:

public function foo() {   dd($this->$date); } 

needs be

public function foo() {   dd($this->date); }
