如何遍历复选框数组和MySQL数据库而不会重叠？

for($j = 0; $j < $length; $j++){
    while($answersRow = mysql_fetch_row($fetch)){
        if($answersRow[0] == $curr_answer_id[$j]){ 

            echo \"<input type=\'checkbox\' value=\'$answersRow[0]\' checked>$answersRow[1]</input> \";           
        } else {

            echo \"<input type=\'checkbox\' value=\'$answersRow[0]\'>$answersRow[1]</input> \";           
        }
    }
}

for

mysql_data_seek()

//> FIRST LOOP
  while($row = mysql_fetch_assoc($query)) {
    $rows[] = $row; //> Saving in the $rows array
    //> All your code from your first loop
  }

//> SECOND LOOP    
  foreach($rows as $v) {
   //> All your code you need for your second loop without any additional query
  }

$firstLoop = \'\';
$secondLoop = \'\';
while() {
   $firstLoop .= \'<option> [...]\';    
   $secondLoop .= \'<div> [...]\';
}

$firstLoop

$secondLoop
