Creating 2 instance of a class and accessing next result set

[CurlyBuilder]

Hi Guys,

I am stuck with something, may be very simple for you guys to solve. May be some basics PHP 5.

I have a DataAccessLayer.class.php, BusinessLayer.class.php, Config.class.php, customException.class.php and Testing1.php(which is my UI).


Query:
1. When I tried to 2 instance of my BusinessLayer in my Testing.php first instance gets created without any problem, but not able to create the 2 instance.
2. When I tried to add the customException.class.php to my BusinessLayer.class.php it breaks down.
3. Not able to access my next result after function call 

below is my code.

-----------------------------------------------------------------------------------------------------

class DataAccessLayer

{
private $connect_mysqli; 

public function __construct()
{
	include 'CustomException.class.php';
	$this->DatabaseConnectionObject();	
}	

/* DatabaseConnectionObject creates database connection objects */
private function DatabaseConnectionObject()
{
	try
	{

	include 'Config.class.php';
	$this->connect_mysqli = new mysqli($Config_HostName,$Config_UserName,$Config_Password,$Config_Database);

	if (mysqli_connect_errno()) 
	{
		printf("Connect failed: %s\n", mysqli_connect_error());
	}
	else
	{
		printf("Connect successful");
	}
	}
	catch(customException $ex)
	{
		$ex->ProcessErrorMessage();
	}
}

/* ExecuteSP is for obtaining data by passing stored procedure names */
public function ExecuteSP($StoredProcedureName)
{
	try
	{
		return $this->connect_mysqli->query("CALL ".$StoredProcedureName."()");
	}
	catch(customException $ex)
	{
		$ex->ProcessErrorMessage();
	}
}
}

-----------------------------------------------------------------------------------------------------

class customException extends Exception
{
  public function ProcessErrorMessage()
	{
		include 'FileOperations.class.php';
	$errorMsg = " \r\n ".'Error on file : '.$this->getFile()." \r\n ".'Error on line : '.$this->getLine()." \r\n ".'Error Message : '.$this->getMessage()." \r\n ".'Error date : '.time()." \r\n ";

	$FileOperation = new FileOperations();
	$this->$FileOperation->WriteErrorLog($errorMsg); 
    	}
}

-----------------------------------------------------------------------------------------------------

class BusinessLayer
{
private $objDataAccessLayer;

public function __construct()
{
	//include 'CustomException.class.php';	// when I include this file it gives error	
	$this->Initalize();

}

private function Initalize()
{
	include 'DataAccessLayer.class.php';
	$this->objDataAccessLayer = new DataAccessLayer();
}

public function GetCityByState($ParamArray)
{
	try
	{	
	return $this->objDataAccessLayer->ExecuteSPwithParameters('SP Name',$ParamArray);
	}
	catch(customException $ex)
	{
		$ex->ProcessErrorMessage();
	}
}

public function GetCountry()
{
	try
	{
	return $this->objDataAccessLayer->ExecuteSP('SP name');
	}
	catch(customException $ex)
	{
		$ex->ProcessErrorMessage();
	}
}
}

-----------------------------------------------------------------------------------------------------

Testing1.php

include 'BusinessLayer.class.php';
$newtest = new BusinessLayer();

$resultset = $newtest->GetCityByState($testarray);

// process the $resultset


$resultset1 = $newtest->GetCountry();
print 'query 2 - 1'; // It works fine perfectly up till here. (May be it's not providing the next result set to process - that's my guess).

// process the $resultset

-----------------------------------------------------------------------------------------------------


Please let me know what am I doing wrong.


Thanks in advance.
