Drupal 6.x

Hello,

I´ve got site running on Drupal 6. Shall I upgrade it to 7 or 8? Can you tell me please advantages and disadvantages of upgrading to 7 or 8?

Thanks

I want to create a registration form for a non profit organisation. A form where i will specify he amount for a conference and participant can pay with credit card or paypal. 

Can somebody help me understand the Drupal 6 LTS patch process.

Can I simply do the following and it will bring my up to current security release (including past patches since 6.38)?

1. Download drupal-core-sa-2018-004-d5-2965601-43.patch

2. Move the patch to my drupal directory

3. Execute: patch -p1 < drupal-core-sa-2018-004-d5-2965601-43.patch

warning: array_keys() expects parameter 1 to be array, null given in xxx.tpl  on line 48.

warning: min(): When only one parameter is given, it must be an array in xxx.tpl  on line 48.

$area = explode('-', check_plain(arg(2)));
foreach ($area as $i => $v) {
  $area[$i] = ucfirst($v);
}
$area = implode(' ', $area);

$total_available = $view->total_rows;

Line 48: $area = implode(' ', $area);

// This site is running on Version 6 (Yes I know, upgrade.. client refuses) Any suggestions?

I am trying to loop through the fields in my database using the following code but nothing is being output

[php]

$fp = fopen(realpath('./') .'/'. file_directory_path() .'/auto-csv/'. $filename, 'w+');
      $data = db_result(db_query("SELECT * FROM {actionmedicalresearch_gdpr_optin}"));
      foreach ($data as $fields) {
        fputcsv($fp, $fields);
      }

[/php]

Please advise
