Drupal 7：选择下拉列表中不需要的字符

Question

What I need is a dropdown that default is blank. It has a '-create new client-' field and then a list of clients. Here is the code for the menu field:

$form['client']['existing'] = array(
  '#title' => t('Client'),
  '#type' => 'select',
  '#options' => array('add' => t('add new client'),$fullName),
  '#empty_option' => '',
  '#description' => t('Select an existing Client or choose -create new client-'),
);

Here's the function I use to populate $fullName:

function myForm_get_names()
{
  $query = db_select('client', 'c');
  $query->fields('c', array('cid','fname','lname'));
  $fullName = array();
  $result = $query->execute();

  foreach ($result as $r)
  {
    $fullName[$r->cid] = $r->fname . " " . $r->lname;
  }
  return $fullName;
}

Here's the print out of $fullName

array (
  1 => 'tim arthur',
  2 => 'val brant',
)

Everything works great. The only problem is it inserts a number after -add new client-. so it's looks like:

Client:
blank
-add new client-
0
  tim arthur
  val brant

I printed out the values of my option field:

'#options' => array(
  'add' => 'add new client',
  0 => array(
    1 => 'tim arthur',
    2 => 'val brant',
  ),
),

the number increases if I give -add new client- a numeric value. For example, if I do:

'#options' => array ('5' => '-add new client-', $fullNames),

then the 0 turns to a 6.

Any ideas on how I can get my array to not be nested. I also tried this, but got an error:

'#options' => array (
  'add' => '-add new client-', 
  array_keys($fullNames) => array_values($fullNames)),

Turns out the solution was quite simple. So instead of

'#options' => array('add' => t('add new client'),$fullName),

just do

'#options' => $fullName,

and then in my myForm_get_names() function instead of

$fullName = array();

do

$fullName = array('add' => '-add new client-');

didn't have to change anything else. h0tw1r3's array_merge idea was crafty tho.
