I'm using a PHP framework someone built that allows for easier use of the Autotask ticketing/CRM system API. I have been able to navigate querying the database, but cannot seem to read through the data it returns. A var_dump of the results shows the following:

object(ATWS\AutotaskObjects\QueryResponse)[9]
  public 'queryResult' => 
    object(ATWS\AutotaskObjects\ATWSResponse)[10]
      public 'EntityResults' => 
        object(ATWS\AutotaskObjects\ArrayOfEntity)[11]
          public 'Entity' => 
            array (size=500)
              ...
      public 'EntityResultType' => string 'contact' (length=7)
      public 'EntityReturnInfoResults' => 
        object(ATWS\AutotaskObjects\ArrayOfEntityReturnInfo)[1028]
          public 'EntityReturnInfo' => 
            array (size=500)
              ...
          public 'Fields' => null
          public 'UserDefinedFields' => null
      public 'Errors' => 
        object(ATWS\AutotaskObjects\ArrayOfATWSError)[1027]
          public 'ATWSError' => null
          public 'Fields' => null
          public 'UserDefinedFields' => null
      public 'ReturnCode' => int 1

Can someone please give me guidance on how I can get to the data in this result. I'm trying to get my hands on the "EntityReturnInfo" data. A sample is as follows

Here is what a print_r returns


ATWS\AutotaskObjects\QueryResponse Object ( [queryResult] => ATWS\AutotaskObjects\ATWSResponse Object ( [EntityResults] => ATWS\AutotaskObjects\ArrayOfEntity Object ( 

**THIS IS WHERE THE GOOD DATA STARTS***
