Answer 1

On the PHP end, you need to actually output that by passing it to echo:

echo $_POST['temp'];

Answer 2

Try this

$(document).ready(function() {

                    $.ajax({
                          url: 'server.php',
                          type: 'POST',
                          data : "temp=100",
                          success: function(data) {
                            alert('Load was performed.');
                        }   
                });

});
