You can "helllllllllllllllllllllllllllllllllllllllllp" us, by firstly removing whatever it is that is sticking your 'l' key down, then by posting any code you have already started with.

Well for a simple example you could do something like this:

 

<?php
/**
* All my Error defines
*/


// Few Options
define('DISPLAY_ERROR', true);
define('LOG_ERROR', true);
define('LOG_DB_TABLE', 'error_logs');

// Database Error Messages
define('E_DB_CONN', 'Error connecting to the database');
define('E_DB_QUERY', 'There was an error in the query');

// User Login Error Messages
define('E_USER_LOGIN', 'You have entered and invalid username or password');
define('E_USER_TIMEOUT', 'Your session has expired, please login again');

// Define my custom error levels
define(-1, 'E_DB');
define(-2, 'E_USER');


// etc...

class ErrorMsg
{
    protected $_EMSG    = NULL;
    protected $_ETYPE   = NULL;
    
    function __contrcut($errorID = 0, $errorMSG = '')
    {
        switch ($errorID) {
            case -1:
                $this->_ETYPE   = 'Database Error: ';
                $this->_EMSG    = $errorMSG;
                break;
            
            case -2:
                $this->_ETYPE   = 'User Error: ';
                $this->_EMSG    = $errorMSG;
                break;
            
            // etc...
            
            default:
                //unknow or unaccounted for error
                $this->_ETYPE   = 'Unknown Error: ';
                $this->_EMSG    = 'An unknown error occured.';
                break;
        }
        
        if (LOG_ERROR) {
            ErrorMsg::logError();
        }
        
        if (DISPLAY_ERROR) {
            ErrorMsg::displayError();
        }
        
    }
    
    function logError()
    {
        // DB Connection stuff
        
        // Exe the DB query
        $db->query("insert into " . LOG_DB_TABLE . " (error_id, error_message, error_time) VALUES ('$this->_ETYPE', '$this->_EMSG', NOW())");
        
        return true;
        
    }
    
    function displayError()
    {
        print "<strong>$this->_ETYPE</strong>: $this->_EMSG";
        
        return true;
    
    }
    
}
?>

 

Please keep in mind this is just an example i just slapped down in a few mins right in this editor, so sorry if the spacing is off etc.. and you would have to really tweek it to get it to work for you but it's an idea anyways, hopefully it will lead you down the right path.

Are you referring to ERRORS or actually handling Exceptions? The latter was introduced with PHP5 and is what most people are working with when it comes to OOP. A little further explanation of what you need would be helpful.
