Are you trying to post JSON data to the server or retrieve JSON data from the server? — Andy E

Use the dataType property to have a JSON response parsed into a native object:

$.ajax({ 
    type: "POST", 
    url: "", 
    data: dataString,
    dataType: "json",
    cache: false, 
    success: function(html){} 
});

If you're trying to post JSON data to the server, you will need json2.js to convert your object into a JSON string before posting it:

data: { json: JSON.stringify(someObj); }

and in php >=5.2:

$data = json_decode($_POST['json']);

this great but know what is the form of php page

@moustafa: I'm not sure I understand what you're asking. Are you asking for the php code to parse the JSON data? If so, see the bottom of my answer.
