fetching arrays from ajax, php/zf

hi,
i'm trying to figure out how to pass arrays back and forth from php to javascript and back in the zend framework. i need to do this for check boxes for a project and i canno use zend_form. i came up with a way to do this but the problem i have is that php cannot read the array string tha i pass to it. the javascript i used looks like this:
PHP Syntax (Toggle Plain Text) 
  1. var cur="";
  2.     var ajaxfields="";
  3.     alert("field count:"+fields.length);
  4.  
  5.     if (fields.length > 0) {
  6.  
  7.         for (var t=0;t<fields.length;t++){
  8.  
  9.             ajaxfields=ajaxfields+escape(fields[t])+"="+escape(document.getElementById(fields[t]).checked)+"&";
  10.  
  11.         }
  12.  
  13.         alert("ajaxfields:"+ajaxfields);
  14.  
  15.         var url="/articles/delete-field"
  16.         var param="c=delete&"+ajaxfields+"sid="+Math.random();
  17.         //alert("param");
  18.         vpMakePostRequest(url, param, deletedone)
  19.     }
  20. }

when i alert the ajaxfields, this is how the string looks like:

ajaxfields:47=false&48=false&49=false&50=true&51=false&52=false&53=false&.

in th php script, i get the c paramemter using(zend):

PHP Syntax (Toggle Plain Text) 
  1. 	$this->c = $_POST['c'];
  2. 		echo $this->c;
i echo for debugging purposes and i get "delete".
now the problem is fetching the array string so i gp-could go ahead with the script.
NOTE: i couldn't fetch it the same way.

can anyone help me out

have javascript send the script a comma seperated list of only the checked check boxes.

then change:

PHP Syntax (Toggle Plain Text) 
  1. var param="c=delete&"+ajaxfields+"sid="+Math.random();

to

PHP Syntax (Toggle Plain Text) 
  1. var param = "c="+ajaxfields+"&sid="+Math.random();

then in the php, get the values into an array by using

PHP Syntax (Toggle Plain Text) 
  1. explode( ',',$_POST['c'] );
