Using ReflectionProperty, it's possible. You could create a helper function if you want to make it less verbose:

<?php
function P($obj, $name)
{
  return new ReflectionProperty($obj, $name);
}

class Foo
{
  public $a;

  public function __construct()
  {
    foreach (array_keys(get_object_vars($this)) as $name)
    {
      if (P($this, $name)->isPublic())
      {
        echo "Public\n";
      }
    }
  }
}

new Foo();
