passing a javascript variable to a php function and quoting it correctly

Im using Zend Framework one of my phtml file's i have this code

 function foobar(id,type){
   var idarray =  <?php AppNamespace_General::getparentids( ?>id, type<?php ) ?>; // here  the id and type are from js
//the php function returns a json array to the js variable
  location.href = baseurl +'/somepage/id/'+id;

How can i correctly pass the js elements to the php function

The php function(Already thought of doing it via ajax..its quite complex)

public static function getparentids($id, $type, $elmarray = '') {

        if (empty($elmarray)) { //avoiding redeclaration of array
            $elmarray = array();
        switch (strtolower($type)) {
            case 'group':
            case 'product':
            case 'specification':

                $gp_handler = new PackAssist_Model_DbTable_Groups();
                $q = "SELECT * FROM t_groups WHERE group_id = $id";
                $sql = $gp_handler->getAdapter()->query($q);

            case 'part':
                $pt_handler = new PackAssist_Model_DbTable_Parts();
                $q = "SELECT * FROM t_parts WHERE part_id = $id";
                $sql = $pt_handler->getAdapter()->query($q);
        $result = $sql->fetchAll();
        $i = 0;
        if (count($result) > 0) {
            foreach ($result as $row) {
                if (isset($row['group_parent_id']) && $row['group_parent_id'] != 0) {
                    if (in_array($row['group_id'], $elmarray)) {
                        $e = $row['group_parent_id'];
                    } else if ($row['group_parent_id'] != 0) {
                        $e = $row['group_id'];
                } else if (isset($row['part_group_id'])) {
                    $e = $row['part_group_id'];
                } else if ($row['group_parent_id'] == 0) {
                if (isset($e) && !empty($e)) {
                    array_push($elmarray, $e);
                self::getparentids($e, 'group', $elmarray);
        } else {
            array_push($elmarray, $id);
        array_pop($elmarray); //removing the group of super parent group which we dont need

        if ($i == 0) { // just encode the array only once
            echo json_encode(array_reverse($elmarray));


If you use jQuery, you can do the following to execute the JSON request:

    type: 'GET',
    url: '/path/to/script.php',
    data: '{ id: '+id+', type: '+type+' }',
    contentType: 'application/json',
    dataType: 'json',
    success: function(data) {
         dataObject = JSON.parse(data);
         // process data
        error: function(e) {

You can use your existing PHP code with this solution. The url you point to would just have to print the JSON result, as you are currently doing in getparentids().

Conditional execution based on short-circuit logical operation

As the evaluation of logical operators &amp;&amp; and || are defined as "short circuit", I am assuming the following two pieces of code are equivalent:
