I had the same issue. The serialized array is an array of name:xxx, value:....

Here's what I did to convert it to a PHP object.

 $data=json_decode(file_get_contents("php://input"));
 $obj=new \StdClass;
     foreach ($data as $row){
      $key=$row->name;
      $value=$row->value;
      $obj->$key=$value;
  }

So, here, it is iterating through the JQuery serialized array, and creating a PHP object property with the "name" value, and giving the property a value with the "value" value.

In general, you should not have to unserialise the data.

If the data is being passed as the for parameters, then the following will suffice.

$form_values = $_POST;
print_r($form_values);

However, sometimes you might want to pass serialised string as one of the fields of the form. In this case, you can use something like the following:

$form_values = $_POST;
$serialised_form_value = $form_values['some_field_from_form'];
parse_str($serialised_form_value, $field_value);
print_r($field_value);

sorry reposted my answer 100% work for my work correctly jquery => 

var data = $('form').serialize();
            $.post(baseUrl+'/ajax.php',
                    {action:'saveData',data:data},
                    function( data ) {
                        alert(data);
                    });

php =>

parse_str($_POST['data'], $searcharray);
    echo ('<PRE>');print_r($searcharray);echo ('</PRE>');

output =>

[query] => 
[search_type] => 0
[motive_note] => 
[id_state] => 1
[sel_status] => Array
    (
        [8] => 0
        [7] => 1
    )

and You can do whatever what you want like with "$searcharray" variable data, thanks to Aridane https://stackoverflow.com/questions/1792603

You need not unserialize anything. The function's name is a bit misleading. jQuery's .serialize() creates a string representation of the form just like as if it was sent by a regular form, for example, calling .serialize() on the following form:

<input name="a" value="foo" />
<input name="b" value="bar" />

will result in this string:

a=foo&b=bar

If you modify your ajax call to:

$.post('data.php', $('form').serialize(), function (output) {...});

Your form will simply be in $_POST, ready to use.

How about simplify it to:

<script type="text/javascript">
// index.php
function get(){
    $('#age').hide();
    $.post('data.php',$('form').serialize(),
        function (output){
          $('#age').html(output).fadeIn(1000);
    });
}
</script>

and in data.php 

<?php
    $name=$_POST;
    echo var_dump($name);  
?>

Using serialize here is same as a form submit.

Well, you are sending a JSON object to your PHP script so you should use json_decode()

Ultimately you are not getting any results because the $_POST data is interpreted as a string, granted a string with JSON syntax but still nothing but a simple string to PHP. To get the contents you must use the json_decode() function linked to above. By default it will return a stdClass object, pass true to the second parameter to return an associative array

// return stdClass or null on error
$jsonData = json_decode($_POST['name']);

// return associative array or null on error
$jsonData = json_decode($_POST['name'], true);

You should make sure to check if there is a value stored in $_POST['name'] before using it.
