Here is the ajax request

$.ajax({
          url:'session.php',
          data:{userdata:JSON.stringify(data)},
          method:"POST",
          success:function(data){
              alert(data);
              console.log(data);
          },
          error:function(err){
             alert('error'+err);
            }
       });

In php

$arr=json_decode($_POST['userdata']);
foreach($arr as $v){
    print_r($v);
}

Getting this error

Invalid argument supplied for foreach

You have error in your json syntax

Your json should be

 var data =  '[{"ratetype":"Y","hotelPackage":"N","roomtype":"Deluxe Double Room","roombasis":",Complimentary Wi-Fi Internet, Breakfast, ","roomTypeCode":"0000015468","ratePlanCode":"0000120709","ratebands":{"validdays":"1111111","wsKey":"fOnrQW3wP9U6eaST9cxEwNldIVM6N6LdxDrDapJ4gq4xUB8SLli5fMQ6w2qSeIKuoaZbT2or8tYkqYfjzPL9wNTRsJN40fffmk9s1Uz6PbbEOsNqkniCrsHjlG4I7MKBayEyj9KbhxGqp8tN23vC5K+lzg+CLhCVc4A727IY+8t1uCj9hv8OAqYPqiatWpH/7ANOsUaHXl4UGSHhnwqssBs1/1meUilvdkgIrhy7u2+1TW+z1jMN3+lQQ1KvLvexxDrDapJ4gq7WpqakyUIlysQ6w2qSeIKu5a8gxPgjph7EOsNqkniCrumRpycuiwkwcJ1QcdikvX8AIeS1LF1SedADwU6eU9IaCaZCAig5yMBccvSRKT+W+ZsfPoLN5c0IliYMwnHbAfXwhKi3O/+L9SyeKeLupHtA9S+XKwz97LvEOsNqkniCrvIh6xV3cNuuKS12MjOBUQSs4y2qNXPFKw==","extGuestTotal":"0","roomTotal":"4350","servicetaxTotal":"466","discount":"385.0","commission":"0","originalRoomTotal":"3965"}},{"ratetype":"Y","hotelPackage":"N","roomtype":"Super Deluxe Double Room","roombasis":",Complimentary Wi-Fi Internet, Breakfast, ","roomTypeCode":"0000017101","ratePlanCode":"0000120713","ratebands":{"validdays":"1111111","wsKey":"mPRyZ7i+l3d9YkBTbyd4CsQ6w2qSeIKubc0g8TGBVVSbBYEQK7zdOgbJJqjW5wOwiG065xYCyu+vVu5bgidY3mfECYFCkMSIn4KACQv3zPbHDVCqduGZ/cYclnMQGbwGDufqO8lYtnyH9KjpH"}}]';

You want to do the following:

foreach($arr->data as $mydata) {
  echo $mydata->ratetype . "\n";
}

Replace ratetype with the appropriate data you are looking for.
