Iteration question when reading CSV

[ppat60]

My last issue at last . I have uncovered a poor logical error on my part. I hope the CSV file and being reading it in(that was the easy part).

I only want to read in the first 4 turns/players and store their data(okay that wasn't to bad either). I am using a for loop for that one. Then I use a while loop to continue reading the CSV file. And that is where my issue is. When the While loop starts to read, it starts at the top of the file(CSV). So my question is how can I read the first four lines/players info then transition into reading from line 5 to the end with out re-reading the first four lines? Here is how I currently have it set up below.

//Open file to read
 $handle = fopen("YellowWins.csv", "r");
   for($i = 0; $i < 4; $i++)
   {
          $data = fgetcsv($handle, 1024, ",");
        // read in first four turns before while loop.
          if($i == 0){
              echo $i. " Begin <br>";
              $Player_Array[0][0] = $data[0];
              $Player_Array[0][1] = $data[1];
              $Player_Array[0][2] = "Route One";
              $Player_Array[0][3] = $RouteOne[0];
              $Player_Array[0][5] = $RouteOne;
              $Player_Array[0][6] = $Player1;
              $whichPlayerInstance = $Player1;
              Enact_Turn($data, $Player_Array,$whichPlayerInstance,$RouteTwo,$RouteThree);
          }
          elseif($i == 1){
              echo $i. "<br>";
              $Player_Array[1][0] = $data[0];
              $Player_Array[1][1] = $data[1];
              $Player_Array[1][2] = "Route One";
              $Player_Array[1][3] = $RouteOne[0];
              $Player_Array[1][5] = $RouteOne;
              $whichPlayerInstance = $Player2;
              $Player_Array[1][6] = $Player2;
              Enact_Turn($data, $Player_Array,$whichPlayerInstance,$RouteTwo,$RouteThree);
          }
          elseif($i == 2){
              echo $i. "<br>";
              $Player_Array[2][0] = $data[0];
              $Player_Array[2][1] = $data[1];
              $Player_Array[2][2] = "Route One";
              $Player_Array[2][3] = $RouteOne[0];
              $Player_Array[2][5] = $RouteOne;
              $whichPlayerInstance = $Player3;
              $Player_Array[2][6] = $Player3;
              Enact_Turn($data, $Player_Array,$whichPlayerInstance,$RouteTwo,$RouteThree);
          }
          elseif($i == 3){
              echo $i. "<br>";
              $Player_Array[3][0] = $data[0];
              $Player_Array[3][1] = $data[1];
              $Player_Array[3][2] = "Route One";
              $Player_Array[3][3] = $RouteOne[0];
              $Player_Array[3][5] = $RouteOne;
              $whichPlayerInstance = $Player4;
              $Player_Array[3][6] = $Player4;
              Enact_Turn($data, $Player_Array,$whichPlayerInstance,$RouteTwo,$RouteThree);
          }
          else{
            echo("Sorry there was a system var i problem");
          }
       echo "<br>" .$i. " end of for loop <br>";
   }
   //Open class to read csv into data
   while (($data = fgetcsv($handle, 1024, ",")) !== FALSE)
   {
     Enact_Turn($data, $Player_Array, $whichPlayerInstance,$RouteTwo,$RouteThree);
   }
   echo"<br> -- END OF FILE -- ";

Thank you for your time!

jpadie,

Thanks for your time and help. I tested what you wrote, but I had some issues. I am using php -v 5.1.2 my first isshe was an Unexpected while in the while(while(... when I dropped one of the while statement then I had object issues, because I need $Player_Array[0-3][6] to call a member function and it is failing so it causes a fatal error... I will look at it more when I am in a bit... do you have any other ideas for a work around for this? I thought this was really slick move to eliminate some code redundancy.

Thank you...
pat

the double while was cut and paste gone wrong.

i don't understand your second point. i cannot see any objects in your posted code.

I will post the entire code. Warning... this is very ugly and was planned for a reason to be like this to some degree.. Here we go.
