And this is the JSON code: http://pastebin.com/dH16RriT
When I try to transform that and read it comes with NULL data.
$data = json_decode($results, true); // $results is a variable with
the JSON content from the URL above
echo $data['tripOption']['saleTotal']; // just an example

Answer 1

yes , you should use
print_r($a['trips']['tripOption'][0]['saleTotal'])
if you want to read the data inside that array,you can do as follows:
$data = json_decode($s,true);
foreach ($data['trips']['tripOption'] as $item){
print_r($item['saleTotal'] . "\n");
};

Answer 2

I have no problem to decode that data from the json structure you posted. Here is a trivial example script which dumped the decoded array structure:
<?php
$json = file_get_contents('./data.json');
$data = json_decode($json, true);
print_r($data);
About the specific data you try and fail to extract: you have to take care to use the correct "path" inside the data structure. This one works:
print_r($data['trips']['tripOption']);
Since that one is an array yo have to address a specific entry in there to get the output you expect:
echo $data['trips']['tripOption'][0]['saleTotal']; // just an example
