Right now, I have this code where $obj_arr maybe contain array and an object.

$obj_temp = array ($obj_identity, $arr_user, $obj_locale, $arr_query); 

foreach ($obj_temp as $maybe_arr) {
        if (is_array($maybe_arr)) :
            $name = (string) key($maybe_arr);
        if (is_object($maybe_arr)) :    
            ???? // how to retrieve a class name ?

        $obj_arr[$name] = $maybe_arr;



function obj_will_be_extract($obj_arr) {

    //Do the rest


I need to create an array consist of combination of objects and arrays. Cause I need to extract it, then how to get an object name?



Use get_class to get the class name of an object.

If you could index the array by gear or some unique value, it would be a lot easier.

$indexed = array();

// create an array using 'gear' as the index
foreach($arrayValue as $value) {
    $indexed[$value['gear']] = $value;

// loop over each object
foreach($objectArray as $obj) {
    $value = $indexed[$obj->gear]; // find the corresponding array
    foreach($value as $name => $val) {
        $obj->$name = $val; // assign each array index/value pair to the object

If possible to get your code to return the array with the index by default, you can remove the first foreach loop.

Hope that helps.

You either iterate the array, searching for the particular record (ok in a one time only search) or build a hashmap using another associative array.

For the former, something like this

$item = null;
foreach($array as $struct) {
    if ($v == $struct->ID) {
        $item = $struct;

See this question and subsequent answers for more information on the latter - Reference PHP array by multiple indexes

I got it! Actually , I could do it by this code:

Instead of putting just :

user = db.users.findOne({userName:"And"})

I did just :

  var user = db.users.findOne({userName:"And"})



returns the ObjectId("someId") , if I want to keep it in some variable I do:

var Id = user._id. 

About the second question, I dont know.
