here is the code to convert javascript array to php array..... this is done with cookies...

function getCookie(c_name)
{
var i,x,y,ARRcookies=document.cookie.split(";");
for (i=0;i<ARRcookies.length;i++)
  {
  x=ARRcookies[i].substr(0,ARRcookies[i].indexOf("="));
  y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1);
  x=x.replace(/^\s+|\s+$/g,"");
  if (x==c_name)
    {
    return unescape(y);
    }
  }
}

function setCookie(c_name,value,exdays)
{
var exdate=new Date();
exdate.setDate(exdate.getDate() + exdays);
var c_value=escape(value) + ((exdays==null) ? "" : "; expires="+exdate.toUTCString());
document.cookie=c_name + "=" + c_value;
}

function checkCookie()
{
    var a_php = "";
    var a=new Array(); 
/*

• 3 json encode then store into the cookie, decode back in php – venimus Commented Jun 13, 2011 at 13:12
• @Marcel Korpel @Luzhin @venimus i need to convert javascript array to php array without using cookies... how can we do that.... any efficient way??......... – learnfromothers Commented Jun 13, 2011 at 13:15
• 3 i assume you will use it in a PHP script, then you could use a_php=encodeURIComponent(JSON.stringify(a)) then use a_php as a GET or POST parameter to the php script that uses it. there you decode it with json_decode(rawurldecode($_GET['a_php'])) – venimus Commented Jun 13, 2011 at 13:29

Sometimes it is not possible to change server side to change output to json. I had input in the form i.e. [ ['azz2465014416', '8', '22'],['azz2465014418', '10', '22'],['azz2465014420', '12', '22'],['azz2465014422', '14', '22'] ]

and I get php array from this input using this php code:

<?php
$a = "[ ['azz2465014416', '8', '22'],['azz2465014418', '10', '22'],['azz2465014420', '12', '22'],['azz2465014422', '14', '22'] ]";

$b = '$c = '.(str_replace(array('[',']'),array('array(',')'),$a)).';';
eval($b);
print_r($c);

you will have then in varible $c resulted output. This is not ideal solution. It will not cover every javascript array, but if you have trouble with some array, you can change it to cover your situation.

In JS:

var a, s;
a = [ 'one', 'two', 'three'];
s = JSON.stringify( a );

//Do something to send `s` to the server in a request

In PHP, assuming s came from client in a cookie

<?php
$a = json_decode( $_COOKIE['s'], true );

Simple as that.

You Should Post it to another(or current) page to be processed with PHP. If you don't want page to be redirected Use AJAX to send Array to PHP.

You can use JSON to do this. On the JavaScript-side, just use JSON.stringify(theArray); to create a JSON-representation of that array. In PHP you can use json_decode(theString, true); to get the array Links: http://php.net/manual/function.json-decode.php http://en.wikipedia.org/wiki/JSON
