Passing global variables in a class

[gansai]

How could I pass global variables to set of functions within a class

<?php
global $user, $scheme_id, $dept_id;
class segment
{
     private $user, $scheme_id, $dept_id;

	 public function __construct() 
	 {
        $this->user = $user;
		$this->scheme = $scheme_id;
		$this->dept = $dept_id;		
     }

     public function unitseg_set()
     {                  
        $sql = mysqli->query('SELECT userid, sid, dept_name FROM dept WHERE dept_id = '.$this->dept.' AND userid='.$this->user.'');
        foreach($sql as $ss)
        $result = $ss->dept_name;
        return $result;
     }
}
?>

Simple - Don't use globals.

Pass them to the object in the constructor

class segment 
{
    private $user;
    private $scheme_id;
    private $dept_id;
    
    public function __construct($user, $scheme_id, $dept_id) 
     {
        $this->user = $user;
        $this->scheme = $scheme_id;
        $this->dept = $dept_id;        
     }

     //etc
}

$obj = new segment($user, $scheme_id, $dept_id);

Thank You Barand:

How could I call the function from the class segment

$seg = new segment($user, $scheme_id, $dept_id);

$seg->unitseg_set();

In fact, looking at your  previous topic, this is virtually an identical question. Had you considered applying the lesson learned in that one, or did you not learn anything?

$result = $seg->unitseg_set();

Your function returns a result set so use that returned value.

(BTW, if you haven't noticed, you have made the exact same mistake as in your last topic - mysqli conection is not defined in your class or function.)
