Is it redundant to have a PHP object mirror a Javascript object, for database interactivity? -

i'm immersing myself in php , javascript, i'm still new coding methodology , concepts; i'm looking little feedback on tentative approach.

i'm building application user signs up, , gains access "node creation." want save node name , position per user, can log in , see there nodes left them (with correct names.)

my question:

"i planning on having 2 identical objects, 1 in javascript, , other in php... realized, might redundant; if need transfer data database javascript object, unnecessary use php "clone" object middle-man??"

my thoughts might simpler manage (yay oop,) said, i'm new application development , love feedback on matter.

php object example:

    class node {          public $name; // stored js object name         public $position; // stored js object position          function setobject() {                     // set js object name on app load             // set js object position on app load         }     }  ?> 

javascript object example:

node = {         name : $name; // set name     position : $position; // set position      findposition : function() {         // find js object's updated position (when moved)     } } 

i think you're conceiving wrong way.

you calling php object "middle man". in web application, middle man http connection. middle man here whatever data transfer format (json, xml, custom, whatever). doesn't matter client-side scripting how data formatting done, , server doesn't care client code.

the real question should asking need on server-side. purpose of server-side script transform data in database format needed send client, , possibly modify data in response client. need decide kind of methods , properties server-side data have , design code around that. don't try replicate client-side code, because has entirely different purpose.
