Removing elements from an associative array

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.

$array_values is undefined. Did you mean ? $result = array($response); unset(array_values($result['queryLocator'])); This gives Fatal error: Can't use function return value in write context in (unset line). — peter300

$array_values should be replaced by your array variable name @peter — JYoThI

Sorry but $result = array($response); unset($result['queryLocator']); does nothing - no error but the queryLocator key is still present. @jothi — peter300

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 !
