Repeat the file to 2 copise while upload codeigniter - php

Question

In CodeIgniter when I upload a file to a particular folder it uploads two copies of the file
To folder. I mean, it repeats the file, I do not know why.
How do I solve this problem?
thank you.
Controller:
$config['upload_path'] = './files/';
$config['allowed_types'] = 'gif|jpg|png|jpeg|svg|rar|zip' ;
$config['max_size'] = 220048;
$config['encrypt_name'] = TRUE;
$this->load->library('upload', $config, 'catalogupload3');
// Create custom object for catalog upload
$this->catalogupload3->initialize($config);
$this->catalogupload3->do_upload('userfile5');
if (!$this->catalogupload3->do_upload('userfile5')){
$url_file = 'nofile' ;
$file_name = 'false';
$file_size = 'false';
}else {
$this->catalogupload3->data();
$url_file = $this->catalogupload3->data('file_name');
$file_name = $_FILES['userfile5']['name'];
$file_size = $_FILES['userfile5']['size'];
}

}else {
$this->catalogupload5->data();
$url_file_32 = $this->catalogupload5->data('file_name');

Of course it will upload two copies because you ran the function twice:
// first run
$this->catalogupload3->do_upload('userfile5');
// second run
if (!$this->catalogupload3->do_upload('userfile5'))
If you wanna a check do it once:
// this is enough it will run it and return a bool
if (!$this->catalogupload3->do_upload('userfile5'))
