Unserialize PHP Array in Javascript

Question

I have a table with a load of rows of serialized arrays that I plan to request and pass it to JavaScript.

The problem is - is it possible to unserialize with JavaScript rather than PHP ?

Otherwise I will have to load all the rows, loop them and unserialize them and assign them to a temporary PHP array and then json_encode it back to JavaScript which seems highly inefficient if I can send the data still serialized so that JavaScript can unserialize the data when it needs to.

Is there a built in Javascript function that does it or will I have to loop the rows in PHP before I encode it?

Note I am not using jQuery.

EDIT: Example of my serialized data in PHP from my table:

a:8:{i:0;a:2:{i:0;i:10;i:1;i:11;}i:1;a:2:{i:0;i:9;i:1;i:11;}i:2;a:2:
{i:0;i:8;i:1;i:11;}i:3;a:2:{i:0;i:8;i:1;i:10;}i:4;a:2:{i:0;i:8;i:1;i:9;}i:5;a:2:
{i:0;i:8;i:1;i:8;}i:6;a:2:{i:0;i:8;i:1;i:7;}i:7;a:2:{i:0;i:8;i:1;i:6;}}

Answer 1

Php.js has javascript implementations of unserialize and serialize:

http://phpjs.org/functions/unserialize/

http://phpjs.org/functions/serialize/

That said, it's probably more efficient to convert to JSON on the server side. JSON.parse is going to be a lot faster than PHP.js's unserialize.
