When adding element to an array in PHP, last element is added twice

I'm having a weird problem where when I add elements to an array in PHP, the last element is added twice. For example, I create 3 arrays, but when I combine them using array_push() or $array[], it duplicates the last element, giving me 4 arrays. Here's an example:

$master_array = [];
foreach($days as $i=>$day){
    $single_array[$i] = array(
        'id' => $day->id,
        'some_variable' => $day->some_variable
    );
    $master_array[] = $single_array[$i];
}
$result = json_encode($master_array);

If desired output is [1,2],[2,3],[3,4], then it will echo [1,2],[2,3],[3,4],[3,4], duplicating the last element. Seems to be okay until I run the json_encode. Any suggestions?

Why are you doing a multidimensional array for $single_array? You don't need the extra dimension.

$master_array = array();
foreach($days as $i=>$day){
    $single_array = array(
        'id' => $day->id,
        'some_variable' => $day->some_variable
    );
    $master_array[] = $single_array;
}
$result = json_encode($past_appts);
