It is very basic of PHP. $_POST is super-global array of PHP that stores data that was sent to a particular script using POST method.

You can use it as any other PHP array

Code below will output all the keys of $_POST and corresponding values:

foreach ($_POST as $key => $value) {
  echo $key . ' = ' . var_export($value, true);
}

If you know which key you need exactly, you can get it using [] on array like so:

$my_value = $_POST['my_post_field_sent_by_android_app'];
