here is good example for this.

{if is_object($obj)}
  {*=== your code ===*}
{else}
  {*=== your code ===*}
{/if}

we can use is_object to know that this is an object or not.

hope it will help someone..

You can get the specific class of the object as well if needed with $obj|get_class

Example:

{if $animal instanceof Horse}
    <span>Yup, it's a horse class.</span>
{else}
    <span>It is actually a {{$animal|get_class}}</span>
{/if}

Function is_a could be used for this.

{if is_a($customer, 'Customer')}
    YES, instance of Customer
{else}
    NO, Not an instance
{/if}

This is the way to check variable is object of specific class in Smarty. 

if( true eq isset($obj) && true eq is_object($obj) && $obj instanceof 'TestClass' ){
//do something
}

you can call php functions in the smarty code. Try this:

{if $customer instanceof Customer}
    YES, instance of Customer
{else}
    NO, Not an instance
{/if}

Also, it might be good idea to check if the variable is actually set before using it if the controller code has many paths:

{if isset($customer) && $customer instanceof Customer}
    YES, instance of Customer
{else}
    NO, Not an instance
{/if}

try this

if($obj instanceof TestClass )
{
    echo 'yes';
}
else
{
    echo 'no';
}
