如您所见，数组看起来像这样：
[0]
[0]
[0]
[0] => coordinate 1 Latitude
[1] => coordinate 1 Longitude
.....
[40]
[0] => coordinate 41 Latitude
[1] => coordinate 41 Longitude
[1]
[0]
[0]
[0] => coordinate 1 Latitude
[1] => coordinate 1 Longitude
.....
[385]
[0] => coordinate 386 Latitude
[1] => coordinate 386 Longitude
[1]
[0]
[0] => coordinate 1 Latitude
[1] => coordinate 1 Longitude
.....
[18]
[0] => coordinate 19 Latitude
[1] => coordinate 19 Longitude
我希望创建一个递归函数，它将钻取这样一个时髦的数组，基本上只返回带有三个子项的多维数组中的坐标。我尝试了一些事情但是甚至没有接近。
答案 0 :(得分：0)
因为我知道最深层次的坐标，我认为应该这样做......
function cleanArray($coords)
{
$toReturn = array();
foreach ($coords as $thisCoords)
{
foreach ($thisCoords as $finalCoords)
{
$testArray = $finalCoords[0];
$lastArray = $finalCoords;
while (is_array($testArray[0]))
{
$lastArray = $testArray;
$testArray = $testArray[0];
}
$toReturn[] = $lastArray;
}
}
return $toReturn;
}
