Error with arrays/class objects/strtok

[mherr170]

Hello,

I am wondering if anyone could provide some help on a task I am trying to work on. However, I am being stopped by an error that states:

fatal error: Call to a member function on a non-object in /www/student/mherr170/Project2/SunInfo.php

and the line that is refers to is:
$temp2->setRise($second);

Now I have googled this error many times, but no example or explanation seems to help me fully. Here is a simple version of my code:

<?php

$monthVect = array();


class Day
{
    var $sunrise;
    var $sunset;

    function Day()
    {

      $sunrise = "lll";
      $sunset = "asd";

    }

    function getRise()
    {
        return $sunrise;
    }

    function setRise($rise)
    {
        $sunrise = $rise;
    }

    function getSet()
    {
        return $sunset;
    }

    function setSet($set)
    {
        $sunset = $set;
    }

}//end of Day class

class Month
    {
        var $dayVect;// = array();
        var $D;
        function Month($days)
        {
            $dayVect = array();
             for($i = 0; $i < $days; $i++)
             {
                  $D = new Day;
                  //$dayVect[] = $D;
                  array_push($dayVect,$D);
             }
        }
    }//end of Month class

 function initVect()
    {
        $Janm = new Month(31);
        monthVect[] = $Janm;
         **Repeated 11 more times for the 11 months**
    }

initVect();
readIn();
function readIn()
{

    $count = 0;
    $month = 0;
    $day = 0;

    $file=fopen("kutztown.txt","r") or exit("Unable to open file!");

    while(!feof($file))
    {

        if($count < 9)
        {
            fgets($file);
        }

        if($count >= 9 && $count <= 38)
        {
           $month = 0;
           $t = fgets($file);

           $first = strtok($t," ");
           $second = strtok(" ");

           while($second !== false && $first !== false)
           {
              $temp2 = $monthVect[$month]->$dayVect[$day];
              $temp2->setRise($second); // THIS LINE ERRORS
              $second = strtok(" ");
              $month++;
           }
           $day++;
        }
        if($count > 40)
        {
            break;
        }
        $count++;
    }
    fclose($file);
}
?>

Look forward to hearing from you all, thanks!

The first problem I spotted is this:

$sunrise = "lll";

Since $sunrise is a member variable, it should be:

$this->sunrise = "lll";

I suspect that since this error is found throughout your code, it is the source of the problem.

By the way, if you did not know you are using PHP 4 object oriented syntax.
