Invalid GeoJSON for polygon - json

Question

I am trying to plot a polygon on a google map using geojson. Here is the PHP code where I am trying to build the polygon using four bounds values return from the query result array:
$arr3_poly = Array(
"type" => "Polygon",
"coordinates" => Array()
);
foreach ($q->result_array() as $row) {
$arr3_poly["coordinates"][] = Array(
floatval($row['v3_bounds_sw_lat']),
floatval($row['v3_bounds_sw_lng']),
floatval($row['v3_bounds_ne_lat']),
floatval($row['v3_bounds_ne_lng']),
);
}
When I then do json_encode($arr3_poly, JSON_PRETTY_PRINT);, this is the resulting output:
{
"type": "Polygon",
"coordinates": [
[
43.8526377,
-79.0499898,
43.8526509,
-79.0499877
],
[
43.8526546,
-79.0501977,
43.8526678,
-79.0501957
],
[
43.8526716,
-79.0504057,
43.8526848,
-79.0504037
]
]
}
There must be something wrong with this geojson because when I try to validate it at geojsonlint.com it returns with this error saying Failed to validate field 'coordinates' list schema.:
Any ideas what I am doing wrong? Thanks.

This works for me in geojsonlint.com (changed your points slightly to make it not look like a straight line):
{
"type": "Polygon",
"coordinates": [
[
[43.8526377,-79.0499898],
[43.854,-79.051],
[43.8526716,-79.0504057],
[43.8526377,-79.0499898]
]
]
}
However, looking closer at that map, they are in Antarctica, you probably wanted this, which is in Canada, near Toronto:
{
"type": "Polygon",
"coordinates": [
[
[-79.0499898,43.8526377],
[-79.051,43.854],
[-79.0504057,43.8526716],
[-79.0499898,43.8526377]
]
]
}
GeoJSON coordinates:
The order of elements must follow x, y, z order (longitude, latitude, altitude for
coordinates in a geographic coordinate reference system).
Which is the opposite order from a google.maps.LatLng object (that is Latitude, Longitude).
