Laravel 從`MYSQL`數據庫解析`geometry`數據類型到原始坐標

Question

我在 MYSQL 表中有一個名為geofences的geometry （幾何是數據類型和列名）列，我需要將此geometry值解析或轉換為可讀的坐標數組。 所以我有一種方法已經完成了我想要的，但我相信有更好的方法來做到這一點，這是我的方法。

這就是我 select 我的數據庫中的幾何值的方法

 DB::raw("(ST_AsText(geometry)) AS `geometry`")

查詢 output

"POLYGON((46.646748 24.562727,46.645079 24.561795,46.643556 24.563615,46.64539 24.564747,46.646748 24.562727,46.646748 24.562727))"

我在地理圍欄Geofence中添加了一個訪問器。

public function getGeometryAttribute($value): array
    {
        $slice = Str::between($value, '((', '))');
        if ($this->shape_type == 'circle') {
            $slice = Str::between($value, '(', ')');
        }

        return collect(explode(',', $slice))->map(function ($point) {
            $points = explode(' ', $point);

            return [
                'longitude' => $points[0],
                'latitude'  => $points[1],
            ];
        })->toArray();
    }

output 正如我所料

array:6 [
  0 => array:2 [
    "longitude" => "46.646748"
    "latitude" => "24.562727"
  ]
  1 => array:2 [
    "longitude" => "46.645079"
    "latitude" => "24.561795"
  ]
  2 => array:2 [
    "longitude" => "46.643556"
    "latitude" => "24.563615"
  ]
  3 => array:2 [
    "longitude" => "46.64539"
    "latitude" => "24.564747"
  ]
  4 => array:2 [
    "longitude" => "46.646748"
    "latitude" => "24.562727"
  ]
  5 => array:2 [
    "longitude" => "46.646748"
    "latitude" => "24.562727"
  ]
]

如果有人知道處理這種情況的更好方法，請在這里給我建議。 提前致謝。

朱爾斯法官在評論中發現了這個問題。

DB::raw("(ST_AsText(geometry)) AS `geometry`")

應該：

DB::raw("(ST_AsGeoJSON(geometry)) AS `geometry`")

output 現在是：

{
    "type":"Polygon",
    "coordinates":
    [
        [
            [46.646748,24.562727],
            [46.645079,24.561795],
            [46.643556,24.563615],
            [46.64539,24.564747],
            [46.646748,24.562727],
            [46.646748,24.562727]
        ]
    ]
}
