php自定义错误处理用法实例

本文实例讲述了php自定义错误处理用法。分享给大家供大家参考。具体如下：

The $errorno error is occurring at $errorline in
  $errorfile
";
  switch($errorno)
  {
   case E_USER_NOTICE:
   case E_NOTICE:
   $halt_script = false;
   $notify = true;
   $label = "Notice";
   break;
   case E_USER_WARNING:
   case E_WARNING:
   $halt_script = false;
   $notify = true;
   $label = "Warning";
   break;
   case E_USER_ERROR:
   case E_ERROR:
   $label = "Fatal Error";
   $notify=true;
   $halt_script = false;
   break;
   case E_PARSE:
   $label = "Parse Error";
   $notify=true;
   $halt_script = true;
   break;
   default:
   $label = "Unknown Error";
   break;
  }
  if($notify)
  {
   $msg = $label . $error_msg;
   echo $msg;
  }
  if($halt_script) exit -1;
}
$error_handler = set_error_handler("ErrHandler");
echo "
Using Custom Error Handler
";
trigger_error("
Error caused by E_USER_NOTICE
", E_USER_NOTICE);
trigger_error("
Error caused by E_USER_WARNING
", E_USER_WARNING);
trigger_error("
Error caused by E_USER_ERROR
", E_USER_ERROR);
trigger_error("
Error caused by E_PARSE
", E_PARSE);
?>

希望本文所述对大家的php程序设计有所帮助。
