simulating with php-json API, an xml-like json structure

You don't show your code for producing the json. I'm assuming that you have a php array and you're using json_encode.
So, without your php code, difficult to know what to suggest.

You have errors in your json -= missing " and : instead of , (lines 48,57)

Here's an extract of the code:

 function JSONAddRecordToChild(array $Record, $ChildID)

 {       

        $file = file_get_contents("File.json", true);
        $data = json_decode($file, true);   //get json by assoc array
        unset($file);         //prevent memory leaks for large json 

        //only when ID does not exist, write record to json 
        $node = $this->searchJSON($data["Articles"], $ChildID);         //costumized searchJSON methode that returns a matching node
        if($node != null){

            $node = array("SUB-TITLES" => array()); 

            foreach ($Record as $key => $value){ 
                $node["SUB-TITLES"][] = array($key => $value);
            }

            foreach ($data as $child){
                foreach ($child as $son){ 
                    if($son["Article"]['ID'] == $ChildID){ 
                        $data[] = $node;
                    }  
                }
            } 

           echo json_encode($data).;  

           //to be written permanently to file 
        } 
    }

Sure ! i anticipate writing it to my file for permanent
storage if all goes fine. for now, i'm just displaying it on my browser
using:

echo json_encode($data);

once again, thanks in advance

Was bored so cooked up a quick n dirty class. Seems to work Ok..

class jBuilder
{
    public $phpArray=array();
    public $containerName;

    public function __construct($containerName=NULL)
    {
        if($containerName) $this->makeContainer($containerName); 
    }

    public function makeContainer($containerName)
    {
        $this->containerName = $containerName; 
    }

    private function makeJSON($data)
    {
        return json_encode($data, JSON_PRETTY_PRINT);   
    }

    private function makeArrayItem($data)
    {
        return json_decode($data,true); 
    }


    public function getJSON()
    {
        return $this->makeJSON(array($this->containerName=>$this->phpArray));   
    }

    public function addJSONItem($JSONstring)
    {
        $item = $this->makeArrayItem($JSONstring); 
        $this->phpArray[] = $item;  
    }


    public function addItem($itemKey, $itemArray)
    {
        $this->phpArray[] = array($itemKey=>$itemArray);    
    }

    public function addArray($itemKey, $arrayOfItems)
    {
        foreach($arrayOfItems as $itemArray)
        {
            $this->addItem($itemKey, $itemArray);   
        }
    }

    public function sortOnField($itemKey, $sortField, $sort=SORT_ASC)
    {
        $out = array();
        foreach ($this->phpArray as $key => $row)
        {
            $out[$key] = $row[$itemKey][$sortField];
        }
        array_multisort($out, $sort, $this->phpArray);          
    }

}

$c = new jBuilder("Articles");

$c->addItem("Article", array("ID"=>1,
               "title"=>"Origin of man",
               "author"=>"Man and Woman",
               "pubDate"=>"21st Feb, 2014",
               "summary"=>"Both Idiot"));

$c->addItem("Article", array("ID"=>100,
                "title"=>"Origin of Politicians",
                "author"=>"Politicians and Man",
                "pubDate"=>"23rd Feb, 2014", 
                "summary"=>"Inexplicable Idiots"));

$c->addArray("Article", array(array("ID"=>22,
                "title"=>"Bumbling Politicians",
                "author"=>"Politicians and Man",
                "pubDate"=>"23rd Feb, 2014", 
                "summary"=>"Inexplicable Idiots"),
                array("ID"=>50,
               "title"=>"Hole of man",
               "author"=>"Man and Woman",
               "pubDate"=>"21st Feb, 2014",
               "summary"=>"Both Idiot")));

$JSONstring = '{
           "Article":  {
               "ID":111,
               "title":"ABel",
               "author":"Man and Woman",
               "pubDate":"21st Feb, 2014",
               "summary":"Both Idiot"
           }
       }';

$c->addJSONItem($JSONstring);
$c->sortOnField("Article", "title");
echo "<pre>";
echo $c->getJSON();

A million thanks diafol. i seem to be getting it
rightly. but not with the removal of the trailing
array indices. the 0, 1, 2... ith are still showing
in the browser output. as in:

"0": { "SUB-TITLES": [
             {"SUB_TITLE_1": "Just kidding"},
             {"SUB_TITLE_2": "Still Kiddng"},
             {"SUB_TITLE_3": "Dont be offended"}
           ]
     }

"1": {}
"nth": {}..

is there anything that can be done to get rid of this
for ease of readability in future

once again, thanks !

Sorry missed thw bit on subtitles. On my pgone so forgive monkey fingers. Will try to post shortly

Sorry been away for weekend. Been thinking about the structure. Seems all wrong to me now.
If you have an object called articles, wouldn't it be easier to just have the objects without the key "article" - or maybe have the key as the id value

{"Articles":[{111:{"field1": value1,"field2": value2}},{50:{"field1": valueA,"field2": valueB}}]}

or

{"Articles":[{"ID": 111, "field1": value1,"field2": value2},{"ID": 50, "field1": valueA,"field2": valueB}]}
