Question

Hello how can i include url function in photo

{
$messages = '';
$t = [];
$i = 0;
try {
$input = array(
'files' => $file,

$status[] = 1;
if (!file_exists(public_path().'/pictures/contentPhoto/')) {
mkdir(public_path().'/pictures/contentPhoto/', 0777, true);
}
$post_photo=$_FILES['files']['name'];

}
$insertDb = DBDosya::insertPicture($file->getClientOriginalName(), $isim.'.'.$file->getClientOriginalExtension(), '' . Config::get('app.pictures') . '/', '.'.$file->getClientOriginalExtension() );
$t[$i]['id'] = $insertDb;
} else {
$t[$i]['result'] = false;
$mesajlar = $validator->messages();
$htmlMesaj = '';
foreach ($mesajlar->all('<li>:message</li>') as $mesaj) {
$htmlMesaj .= $mesaj;
}
$t[$i]['info'] = $htmlMesaj;
}
$messages .= $t[$i]['info'];
$i++;
}
$status = in_array(1, $status);
} catch (Exception $e) {
return ['status' => false, 'msg' => $messages . '<li>' . $e->getMessage() . '</li>',];
}
return ['status' => $status, 'msg' => $messages, 'data' => $t[0]];
}
It works properly in the files that come with this file.
But I get getRealPath () error when I get photo with url.
How can I handle the photo from the URL with this function
