我尝试在 Mapbox GL Draw 中保存和编辑行,为此我使用 MySQL 和 PHP(要求),并且只将坐标保存在 MySQL 中,但我在 JSON 中进行查询和编码,程序返回这个
"geometry": {
"coordinates": "[[8.971375670640924,39.27952971962691],[9.019097533433808,39.29998983691581],[9.062012877672174,39.27554328682473],[9.125870909898737,39.28643899912291],[9.14097711107047,39.30742839737994],[9.178742614000214,39.30344355258791]]",
"type": "LineString"
}
我需要数值数组中的坐标,这是怎么回事
"geometry": {
"coordinates": [
[
9.06905,
39.248296
],
[
9.111966,
39.26212
],
[
9.135998,
39.239256
],
[
9.039472,
39.25596
],
[
9.042251,
39.25373
]
],
"type": "LineString"
}
它在 MySQL 中的坐标如何 JSON (longtext utf8mb4_bin) 和查询 1 个数据是
while($row = mysqli_fetch_assoc($result_task)) {
$ruta['features'][0]['geometry']['coordinates'] = $row['ruta'];
}
