WSOD due to collation being unexpected in settings.php

Hi
Finally got the connection established, but took a while.
Found this error in error_log at the root of my site:
[15-Dec-2013 17:37:07 America/Denver] PHP Parse error: syntax error, unexpected ''collation'' (T_CONSTANT_ENCAPSED_STRING), expecting ')' in /home4/xxxx/public_html/sites/default/settings.php on line 238

by removing the collation entry from the db connection info, the WSOD went away and I got a nice green checkmark in the limesurvey sync config settings page.

I'm on drupal 7.23

This is now my relevant settings.php stuff:

$databases = array (
  'default' => 
  array (
    'default' => 
    array (
      'database' => 'zzzz',
      'username' => 'zzzz',
      'password' => 'zzzz',
      'host' => 'localhost',
      'port' => '',
      'driver' => 'mysql',
      'prefix' => '',
    ),
  ),
);
/* limesurvey port was 3306 */
/* removed  'collation' => 'utf8_general_ci' since this was causing 'unexpected' error */

$databases['ls']['default'] = array( 
'database' => 'wwww', 
'username' => 'wwww', 
'password' => 'wwww',
'host' => 'localhost',
'port' => '', 
'driver' => 'mysql', 
'prefix' => 'ebi_'
);
