//data for single result ends here
I tried the following code for desired results but no success
foreach ($array as $xm) {
foreach ($xm as $points=>$pointkey) {
foreach($pointkey as $cor=>$corkey) {
echo $cor["coordinates"];
}
}
}
it gives me warning "Warning: Invalid argument supplied for foreach() in foreach($pointkey as $cor=>$corkey)"

Answer 1

Try something like:
$coords = array();
foreach ($data['Placemark'] as $entry) { // where $data holds the complete array
$coords[] = $entry['Point']['coordinates'];
}
var_dump($coords);
For only one result you can access the coordinates directly, like:
var_dump($data['Response']['Placemark']['Point']['coordinates']);

Answer 2

I would do something like this:
$coords = array();
array_walk_recursive($input_array, 'get_coords');
function get_coords($item, $key)
{
$coord = ($key === 'coordinates') ? $item : '';
if(!empty($coord))
{
$coords[] = $coord;
}
}
