Question

我是否可以将$variable从comments（）传递给someFunction（）？

class Blog extends CI_Controller {

public function index()
{
    echo 'Hello World!';
}

public function comments()
{
    $variable = "Hello";
}

public function someFunction()
{
    echo $variable;
}

}

class Blog extends CI_Controller {

    public function index()
    {
        echo 'Hello World!';
    }

    public function comments()
    {
        $_SESSION['variable'] = Array('k1'=>'v1','k2'=>'v2') ;
        // Store the variable in session so it can be called
        // in another page or ajax call
    }

    public function display()
    {
        echo $_SESSION['variable'] ;
    }
}


// my index.php file

var $blog = new Blog() ;
$blog->comments() ;

//another ajax_called.php file, call in ajax on in another browser tab
    var $blog = new Blog() ;
    $blog->display() ;
