Php error string conversion

Question

I have this code. And i need to print those strings. But i can't make changes outside the class. So i need to change inside class to work. The fields must remain private. Any ideas?

class STUDENT {
    private $nume,$prenume;
    # Constructor 
    public function __construct($nume , $prenume){ 
        $this->nume=$nume;
        $this->prenume=$prenume;            
    } 

}

$student = new STUDENT("one","two");  
echo "student: ". $student ."<hr/>";

You have to implement __toString method: php.net/manual/en/language.oop5.magic.php#object.tostring — hindmost

You have to define __toString method. Then you can echo instance as string:

class STUDENT {
    private $nume,$prenume;

    public function __construct($nume , $prenume){ 
        $this->nume=$nume;
        $this->prenume=$prenume;            
    } 

    public function __toString()
    {
        return '{nume:'.$this->nume.','.prenume:'.$this->prenume.'}';
    }
}

$student = new STUDENT("one","two");  
echo "student: ". $student ."<hr/>";

public function __toString(){ return $this->nume." ".$this->prenume; } this is wrong?

You need to use getters and setters so the fields can be read and written. Here's a discussion on the subject: Getter and Setter?
