As a phper, I just found out today that from joining OSC to now, the only code I have shared is php. I felt red and shared a common class I wrote in the project.

GET data/POST data /Ordinary array returns formatted data through key
http://www.du52.com/text.php?id=581
  1. include_once('Param.class.php');
  2. // Simulate setting GET/POST data
  3. $_REQUEST['int'] = '1243';
  4. $_REQUEST['str'] = 'hello';
  5. $_REQUEST['bool'] = 'true';
  6. $_REQUEST['arr'] = '1,2,3,4';
  7. $_REQUEST['json'] = json_encode(array( 'a' => 'a', 'b' => 'b'));
  8. $_REQUEST['date'] = date('Y-m-d H:i:s');
  9. // Single data reading
  10. var_dump(Param::getInt('int', 0));echo '
    ';
  11. var_dump(Param::getInt('undefined-int', -1));echo '
    ';
  12. var_dump(Param::getStr('str', 'default'));echo '

  13. var_dump(Param::getBool('bool', NULL));echo '

  14. var_dump(Param::getStrArray('arr', ',', NULL));echo '
    ';
  15. var_dump(Param::getJson('json' , NULL));echo '

  16. var_dump(Param::getTime('date', -1));echo '
    ';
  17. echo '

  18. // Get batches of
