In the Smarty2 code base, I was using register_object() function as (in businessLogic.php) follows:
class myObject {
public $name;
.....
}

$obj = new myObject();
$smarty->register_object("regobj", $obj);

Then in my template file: mytemplate.tpl, the attribute of the myObject class is as follows:

<table>
<tr>
<td>{regobj->name}</td>
</tr>
<table>

With the above template, the $name value of the $obj is correctly getting rendered in Smarty2.

As the register_object() function is replaced by registerObject() in Smarty3, I have made the
code change (in businessLogic.php) as follows when I migrated to Smarty3:

class myObject {
public $name;
.....
}

$obj = new myObject();
$smarty->registerObject("regobj", $obj);

I tried to render my template file: mytemplate.tpl (without making any changes), but
the $name value of the $obj is did not get rendered in Smarty3. The rendered table cell was empty.
I have read the Smarty3 documentation at URL: http://www.smarty.net/docs/en/advanced.features.objects.tpl, but it did not help as
it gives examples for accessing the methods of the registered object: $obj.

Can someone tell me if there is anything wrong in using of registerObject() function?
Have anyone able to register an object and able to access the attribute of the registered object successfully in a Smarty3 template?

To temporarily overcome the problem, I have used the assign() function in place of Smarty3 registerObject() and it works.
Here is the code that works!

businessLogic.php file:

class myObject {
public $name;
.....
}

$obj = new myObject();
$smarty->assign("regobj", $obj);

mytemplate.tpl file:

<table>
<tr>
<td>{$regobj->name}</td>
</tr>
<table>

The above code worked as expected for me, however, it is not using the same pure-object syntax as it is intended by the use of Smarty3 registerObject() function.

Please let me if you have any better solution.

Code:
<?php

require_once 'smarty-config.php';

class MyClass {
  public function myFunction()
  {
    print 'My function.';
  }
}

$smarty->registerObject('MyClass', new MyClass);
$smarty->display(__FILE__);

__HALT_COMPILER();
?>{$smarty.version}
{MyClass->myFunction}


Code:
$ registerObject.php
3.1.30
My function.


Works as documented in http://www.smarty.net/docs/en/advanced.features.objects.tpl
If you want to access object PROPERTIES, ASSIGN the object. REGISTER works for registering the object as plugin to access its METHODS.
