我正在尝试从数组中获取坐标以添加到Google地图中以输出多边形。
而且我在尝试将我的数组($ ArrayCoords)作为字符串存储到变量中时遇到一些困难。
我有这个数组,其中包含多个lat和lng坐标以及一个缩放:
$ArrayCoords = get_field('Array_Coords');
print_r($ArrayCoords);
/* Print out as:
[draw_map] => Array
(
[coords] => Array
(
[0] => Array
(
[lat] => 38.928713698662
[lng] => -94.537423253059
)
[1] => Array
(
[lat] => 38.927679421508
[lng] => -94.537782669067
)
[2] => Array
(
[lat] => 38.928038315258
[lng] => -94.53973531723
)
[3] => Array
(
[lat] => 38.928171856655
[lng] => -94.54069018364
)
[4] => Array
(
[lat] => 38.928215341202
[lng] => -94.541194438934
)
[5] => Array
(
[lat] => 38.929258624074
[lng] => -94.541215896606
)
)
[zoom] => 13
)
*/
我正在尝试将此数组存储为变量($ latLngCoords和$ Zoom),该变量将作为:
echo $latLngCoords;
/*
38.928713698662, -94.537423253059
38.927679421508, -94.537782669067
....and so on..
*/
echo $Zoom;
// 13
我不确定该怎么做。
感谢所有人,如果我的问题不清楚,我很抱歉:(但我想我用while循环弄清楚了答案:
$Zoom = $ArrayCoords[zoom];
$array = $ArrayCoords[coords];
$arrayCount = count($array) - 1;
//arrayCount is 6, but because of array starting at 0, we need to minus -1
$i=0;
while($i <= $arrayCount)
{
$latLngCoords .= $array[$i][lat] . ", " . $array[$i][lng] . "<br>";
$i++;
}
echo $latLngCoords;
echo $Zoom;
//print_r($array);
