在另一个函数php中获取一个函数的数组输出

Question

I have below controller function of codeigniter,

public function add_attachments($openid)
{
            $config = array(
                    'upload_path' => './uploads/attachments/',
                    'allowed_types' => 'gif|jpg|png|jpeg|doc|pdf',
                    'max_size' => '1024000000',
                    'multi' => 'all'
                ); 
            $this->load->library('upload', $config);   
            if ( ! $this->upload->do_upload())
            {
                $error = array('error' => $this->upload->display_errors()); 
            }
            else
            {
                $data = $this->upload->data();  
            }
            $new_array = array_column ($data, 'full_path');         
}

I can get output of $new_array,

But i want to use this output in another function which is just below that in same class,

example,

public function getback()
{
print_r($new_array);
}

in short, once 1 function is executed, some values stored in variable and need to use in another function,

How can i do that?

Thanks,

Simply pass that value within that function as

public function add_attachments($openid) {
    $config = array(
        'upload_path' => './uploads/attachments/',
        'allowed_types' => 'gif|jpg|png|jpeg|doc|pdf',
        'max_size' => '1024000000',
        'multi' => 'all'
    );
    $this->load->library('upload', $config);
    if (!$this->upload->do_upload()) {
        $error = array('error' => $this->upload->display_errors());
    } else {
        $data = $this->upload->data();
    }
    $new_array = array_column($data, 'full_path');
    $this->getback($new_array);
}

public function getback($new_array = array()) {
    print_r($new_array);
}

Edited

Passing data using js

public function add_attachments($openid) {
   //your code...
   echo json_encode($new_array);exit;
}

Now within your ajax success function

 success:function(data){
     var data = $.parseJSON(data)
     //send it to your another function
 }
