Repeating array... Not supposed to

[DBookatay]

For some reason this array keeps repeating the 1st line onto the 2nd line and the 1st and 2nd line onto the 3rd line, and so on and so on.

 

unset ($grade); $grade = array();
  foreach ($row as $grade => $value) {
  if (substr($grade, 0,1)== "y") {
  if ($grade == "y1") {if ($value == "x") {$grades[] = "1";}}
  if ($grade == "y2") {if ($value == "x") {$grades[] = "2";}}
  if ($grade == "y3") {if ($value == "x") {$grades[] = "3";}}
  if ($grade == "y4") {if ($value == "x") {$grades[] = "4";}}
  if ($grade == "y5") {if ($value == "x") {$grades[] = "5";}}
  if ($grade == "y6") {if ($value == "x") {$grades[] = "6";}}
  if ($grade == "y7") {if ($value == "x") {$grades[] = "7";}}
  }
}
$grades_string = implode(", ", $grades);

 

The dB rows are titled y1, y2 etc.

 

I can show someone a link with the example of what I mean the error is if need be.

Rewrote it, problem was it should of been unset ($grade); $grades = array();

unset ($grade); $grades = array();
  foreach ($row as $grade => $value) {
  if (substr($grade, 0,1)== "y" && $value == "x") {
  if ($grade == "y1") {$grades[] = "1";}
  if ($grade == "y2") {$grades[] = "2";}
  if ($grade == "y3") {$grades[] = "3";}
  if ($grade == "y4") {$grades[] = "4";}
  if ($grade == "y5") {$grades[] = "5";}
  if ($grade == "y6") {$grades[] = "6";}
  if ($grade == "y7") {$grades[] = "7";}
  }
}
$grades_string = implode(", ", $grades);
