autoincrement array values results in Undefined index - El Forum - 10-08-2008

Hi,

i have a tiny problem with an array, this array will cotain database entries by date separated in a negative and positive counter:

Code:
foreach ($votes as $key => $value) {

            $thisDay = date('y-m-j',strtotime($votes[$key]->timeEnter));

            if($value->voting == 1) {

                $voteCount[$thisDay]['pos']++;

            }else{

                $voteCount[$thisDay]['neg']++;    

            }

        }

Whenever $thisDay changes to a new date, i get an error:

Code:
A PHP Error was encountered

Severity: Notice

Message: Undefined index: pos

i know that everytime i try to increment the value for a new date, the key for the array does not exist, which actually causes the problem, but i have no idea how to solve this.

What about

Code:
if($value->voting == 1) {

   if( ! isset($voteCount[$thisDay]['pos'])

   {

      $voteCount[$thisDay]['pos'] = $value->voting;

   }

   else

   {

      $voteCount[$thisDay]['pos']++;

   }

} // rest of the code
