[rajavel]

<?php
class _Error_Handler
{
	var $_e_type;
	var $_e_message;
	var $_e_file;
	var $_e_line;

//Constructor
function _Error_Handler()
{
	$this->_set_handler();
}

//Sets the Error Handler
function _set_handler()
{
	set_error_handler(array(&$this,"handler"));
}

//error Handler
function handler($error_type, $error_message,$error_file, $error_line)
{
	switch($error_type)
	{
		case E_ERROR:
			$this->assign_values("Fatal Error",$error_message,$error_file,$error_line);
			break;
		case E_WARNING:
			$this->assign_values("Warning",$error_message,$error_file,$error_line);
			break;
		case E_PARSE:
			$this->assign_values("Parse Error",$error_message,$error_file,$error_line);
			break;
		case E_NOTICE:
			$this->assign_values("Notice",$error_message,$error_file,$error_line);
			break;
		case E_COMPILE_WARNING:
			$this->assign_values("Compile Warning",$error_message,$error_file,$error_line);
			break;
		case E_CORE_ERROR:
			$this->assign_values("Core Error",$error_message,$error_file,$error_line);
			break;
		case E_CORE_WARNING:
			$this->assign_values("Core WARNING",$error_message,$error_file,$error_line);
			break;
		case E_USER_ERROR:
			$this->assign_values("User Error",$error_message,$error_file,$error_line);
			break;
		case E_USER_WARNING:
			$this->assign_values("User Warning",$error_message,$error_file,$error_line);
			break;
		case E_USER_NOTICE:
			$this->assign_values("User Notice",$error_message,$error_file,$error_line);
			break;
		case E_ALL:
			$this->assign_values("All",$error_message,$error_file,$error_line);
			break;
	}
}

// function used to assign values for member variables
function assign_values($_etype,$_emessage,$_efile,$_eline)
{
	$this->_e_type = $_etype;
	$this->_e_message = $_emessage;
	$this->_e_file = $_efile;
	$this->_e_line = $_eline;

	//If i call the show_error function here it works well
	//$this->show_error();
}

function show_error()
{
	echo "etype = ".$this->_e_type."<br>";
	echo "emessage = ".$this->_e_message."<br>";
	echo "efile = ".$this->_e_file."<br>";
	echo "eline = ".$this->_e_line."<br>";
	exit();
}
}

$eh = new _Error_Handler();
//if i call the show_error function here it is not working
$eh->show_error();

//i want to use like this also
//$eh->_e_type
?>

How does it not work?

if the show_error() function is used within the assign_values() function (eg:

$this->show_error();

) i am getting the output as

etype = Warning
emessage = mysql_pconnect() [function.mysql-pconnect]: Can't connect to MySQL server on '207.46.130.24' (10060)
efile = E:\HiTV\config\configBL.php
eline = 141

if the show_error() function is called outside (eg:

$eh = new _Error_Handler();
$eh->show_error();

) i am getting the output as

etype =
emessage =
efile =
eline =
