jqgrid json数据不适用于json_decode

Question

I have a json string that is posted to the server that looks like this:

{\"groupOp\":\"AND\",\"rules\":[{\"field\":\"screen_name\",\"op\":\"bw\",\"data\":\"aaa\"}]}

It looks pretty good to me, but the problem is the PHP function json_decode returns NULL. I made a codepad example that illustrates the problem here : http://codepad.org/SOJw9cZb . What do I have to do to this string to get json_decode to work properly?

This json string is sent to the server by the jqgrid Filter Toolbar module to identify the search parameters.

Thanks!

Answer 1

var_dump(json_decode(str_replace('\"', '"', '{\"groupOp\":\"AND\",\"rules\":[{\"field\":\"screen_name\",\"op\":\"bw\",\"data\":\"aaa\"}]}')));

works just fine. ie convert the \\" to "

Valid JSON is

{"groupOp":"AND","rules":[{"field":"screen_name","op":"bw","data":"aaa"}]}
