Custom error handling + trigger error + multiple classes

hi i am asking this question again , as i dont know if this is gonna work for me , i have multiple classes with their own internal error handling , my authentication and db classes have both in their constructors something like this $GLOBALS['_ERROR_HANDLER_OBJECT_DB'] = &$this; $GLOBALS['_ERROR_HANDLER_METHOD_DB'] = '_db_catch'; function db_error_handler($type, $message, $file=null, $line=null, $vars=null) { //die(); return $GLOBALS['_ERROR_HANDLER_OBJECT_DB']-> $GLOBALS['_ERROR_HANDLER_METHOD_DB']($type,$message, $file, $line, $vars); } set_error_handler('db_error_handler'); the issue is when i trigger an error within the class the catch function is triggered from the last class that is set but they have different ways of throwing the error here is my catch function function _db_catch($type, $code, $file=null, $line=null, $vars=null) { echo $type; die(); switch ($type) { case E_WARNING: //$_SESSION['php_error'] = $code; $errstr .= "Php Error: $code<br>\n"; $errstr .= "On Line: $line<br>\n"; $errstr .= "In File: $file<br>\n"; //die($errstr); break; case E_USER_WARNING: $this->_throw($code,$file,$line); break; } } here is the throw function, the real code is commented out function _throw($code=null,$file,$line) { //if ($this->show_errors) { die($this->print_body($this->print_error($_SESSION ['sql_query'],$custom,$line,$file,$break))); //} else { // $_SESSION['mysql_error'] = $this->print_body($this- >print_error($query,$custom,$line,$file,$break)); // $this->redirect("mysql_error.php"); //} } basically the throw function for my db class is either going to die to the screen with my own custom db error parsing which will show the query and the mysql error and the line and file or go silently to a friendly error page and email me the error, and the auth class throw function returns to the previous page with a custom error code set in a session which outputs the error message here is the original trigger error function _trigger_error($query=null,$custom_code=null) { //die($custom_code); unset($_SESSION['sql_query']); if ($query) $_SESSION['sql_query'] = $query; $trace = debug_backtrace(); $line = $trace[2][line]; $file = $trace[2][file]; die($this->print_body($this->print_error($_SESSION ['sql_query'],$custom,$line,$file,$break))); //if ($query) $custom_code = $this->print_body($this- >print_error($query,$custom,$line,$file,$break)); //return trigger_error($custom_code, E_USER_WARNING); } as both error handlers in the classes will be triggered from the E_USER_WARNING the last class is going to handle it, i was hoping it would be handled internally , is there anyway to set trigger error up so i can do something like return trigger_error($custom_code, DB_USER_WARNING); and for the auth return trigger_error($custom_code, AUTH_USER_WARNING); so then it is seperated and only the DB_USER_WARNING will trigger the db class and the AUTH_USER_WARNING will trigger the auth class please let me know i'm stumped :\
