Removing elements from an associative array - php

Question

This post describes how to remove an element of an associative array with Unset i.e unset($array['key1']);
I have this array:
Array
(
[queryLocator] =>
[done] => 1
[records] => Array
(
[0] => stdClass Object
(
[Id] =>
[CreatedDate] => 2016-08-28T14:43:45.000Z
[Leader__c] => GF
[Location__c] => Postbridge
[Service_Date__c] => 2016-09-03
[Service_Time__c] => 14:30
[Service_Type__c] => Baptism
)
)
[size] => 42
[pointer] => 0
[QueryResultsf] => SforceEnterpriseClient Object
(
[sforce:protected] => SoapClient Object
(
[trace] => 1
[compression] => 32
[_encoding] => utf-8
[_features] => 1
[_user_agent] => salesforce-toolkit-php/20.0
[_soap_version] => 1
[sdl] => Resource id #8
[packageVersionHeader:protected] =>
[client_id:protected] =>
)
)
)
I want to delete the key [queryLocator], replace the key [done] with [total], replace the key [records] with [rows] and delete all subsequent keys i.e [size], [pointer] etc.
Using unset, i.e unset($array['queryLocator']); has no effect.
What am I doing wrong ? Thanks.

Here is the code that achieves what I wanted - taking output from a Sales Force query and formatting it as required by a EasyUI datagrid.
//--Get the Sales Force Data
$response = $mySforceConnection->query($query);
//--Encode and decode - for some reason
$data = json_encode((array)$response);
$x = json_decode($data,true);
//--Empty Array
$q = array();
//--Add array element for number records
$q['total'] = $numRecs;
//--Copy the array element from original query with data
$q['rows'] = $x['records'];
//--JSON Encode the new array
$y = json_encode($q);
//--Return the array to Ajax call
echo ($y);
And here's a snippet of the validated JSON..
{
"total":193,
"rows":[
{
"Id":null,
"CreatedDate":"2016-08-28T14:43:45.000Z",
"Leader__c":"GF",
"Location__c":"Postbridge",
"Service_Date__c":"2016-09-03",
"Service_Time__c":"14:30",
"Service_Type__c":"Baptism"
},
{
"Id":null,
"CreatedDate":"2016-08-17T20:43:10.000Z",
"Leader__c":"GF",
"Location__c":"Ashburton",
"Service_Date__c":"2016-09-04",
"Service_Time__c":"08:00",
"Service_Type__c":"HC 2"
},
{
"Id":null,
"CreatedDate":"2016-08-17T20:43:10.000Z",
"Leader__c":"GF",
"Location__c":"Bickington",
"Service_Date__c":"2016-09-04",
"Service_Time__c":"09:00",
"Service_Type__c":"HC 2"
},
{
"Id":null,
"CreatedDate":"2016-08-17T20:43:10.000Z",
"Leader__c":"MC",
"Location__c":"Holne",
"Service_Date__c":"2016-09-04",
"Service_Time__c":"10:30",
"Service_Type__c":"HC 1"
},
I struggled a bit with the array manipulation but it works. Any code improvement suggestions most welcome !
