Looping through an Array in Php

Can't seem to figure this out. I struggle so badly with arrays. I am trying to get the data out of this array and keep getting errors.

I tried using this code below and several other attempts and failed miserably. What's the best way to remember how to do this? Everytime I don't code Php for a couple months I seem to forget everything...

  foreach( $data as $key) { 
            foreach( $key as $value => $sum) {
              echo $sum;
            } 
        }





Array
    (
        [result] => OK
        [data] => Array
            (
                [destination] => 
                [tracking] => Array
                    (
                        [0] => Array
                            (
                                [loc] => Array
                                    (
                                        [city] => 
                                        [territory] => ME
                                        [country] => US
                                    )

                                [desc] => Delivered
                                [stamp] => 1384977300
                                [time] => 11/20/13 11:55 am
                                [locStr] => ME, US
                                [geo] => Array
                                    (
                                        [lat] => 45.253783
                                        [lon] => -69.4454689
                                    )

                            )

I think your code is not wrong. you have three dimensional array. you have only two foreach. you have to loop within a loop within a loop. and if you try to echo an array Ofcourse you will have an error so you should check first if that output is an array or not.

In php there are basically two different type of arrays. key/value based array and element based array. An element based array is 

$arr = array("a", "b", "c");
echo $arr[0]; //  prints a
echo $arr[2]; //  prints c

   //  hash - k/v array
   $arr = array("monkey" => "banana", "chicken" => "egg");
   echo $arr["monkey"]; //  prints banana

   //  combination 
  $arr = array( array("monkey" => array("banana", "water")));
  echo $arr[0]["monkey"][1]; // prints water

hope this helps.

iterate through tracking?

if ($arr['result'] == "OK") {

  for ($i=0; $i < count( $arr['data']['tracking'] ); $i++) {
    // do stuff with $arr['data']['tracking'][$i]
  }
}
