The Array looks like:

[
   {
      "results":[
         {
            "signal_id":11328555834,
            "dec_lat":52,
            "dec_long":8


},
         {
            "signal_id":11328549683,
            "dec_lat":53,
            "dec_long":9


},
         {
            "signal_id":11328549682,
            "dec_lat":12,
            "dec_long":6

Solution 1

foreach is a loop, which runs through each of the elements in the array ion turn - which is why it prints all the elements.

If you want to only print the last element, then only use the last index to access the last element.

The Array must be:

HTML

{
      "results":[
         {
            "signal_id":11328555834,
            "dec_lat":52,
            "dec_long":8
         },
         {
            "signal_id":11328549683,
            "dec_lat":53,
            "dec_long":9
         },
         {
            "signal_id":11328549682,
            "dec_lat":12,
            "dec_long":6
         }
     ]
}

$dec_lat = $data["results"][count($data["results"])-1]["dec_lat"];
