访问另一个类中的一个类的数组，而无需在 php 中传递参数

Question

$mile= new mile();

  $get_sales_totals1=mysql_query("SELECT title,deadline FROM milestones where id=$id ");


  while($milestone = mysql_fetch_array($get_sales_totals1)){

    $mile->addne($milestone["deadline"],$milestone["title"]);
 }

I am trying to create an array of objects from database query.Above code is the main.php page and below is the page with classes.I created an array with deadline and title in each item of the array.

class mile {

    public $milearray;

public function __construct(){
    $this->milearray=array();

    }

    public function addne($deadline,$title){
     $ne->deadline=$deadline;
     $ne->title=$title;
     array_push($this->milearray,$ne);
    }

    public function extra(){

    //how to get milearray $this->milearray here

    }

}

Is it possible to get milearray in the function 'extra' in the same class without passing arguments.

OR

class compare is incomplete. I need to call milearray from class 'mile' inside class 'compare' without passing any arguments

    class compare{
   public daycomparearray;
    public function __construct(){
     $this->daycomparearray=array();

    }
    public function comparemile(){
     if($this->daycomparearray== milearrray->deadline)
    // how to get mile array here 
    }
    }

please help me....

Answer 1

You have to pass arguments, otherwise the compare class won't know which objects to compare.

class compare{
    public function __construct(){

    }
    public function comparemile($mile1, $mile2){
        $array1 = $mile1->milearray;
        $array2 = $mile2->milearray;
        // code that compares $array1 and $array2
    }
}

If you can't pass arguments to the comparemile function, maybe it can be done with the constructor.

class compare{
    private $array1;
    private $array2;

    public function __construct($mile1, $mile2){
        $this->array1 = $mile1->milearray;
        $this->array2 = $mile2->milearray;

    }
    public function comparemile(){
        // code that compares $this->$array1 and $this->$array2
    }
}

You tried self ? Like:

public function extra(){
   $array = self::$milearray;
}

or making a session for global vars?
