And in my PHP server. receive the data like down below

if (isset($_POST['btn_preference'])) 
{
$amount = $_POST["age"];
#How can i receive min and Max val ?? 
$_SESSION = $amount;
}

Answer 1

Create 2 hidden inputs with name and id as min and max, then in your event

slide: function( event, ui ) {
    $( "#amount" ).val( "$" + ui.values[ 0 ] + " - $" + ui.values[ 1 ] );
    $( "#min" ).val(ui.values[ 0 ]);
    $( "#max" ).val(ui.values[ 1 ]);
}

then you'll just access them in your PHP as

if (isset($_POST['btn_preference'])) 
{
$amount = $_POST["age"];
$min = $_POST["min"];
$max = $_POST["max"];
}
