How do I create an error handler in php that redirects the user if a specific error occurs?


How do I create an error handler in php that redirects the user if a specific error occurs?

around this issue Don't send any output via "echo" or similar because you can't redirect AFTER you've already started sending out the page.
file_get_contents will return false when it can't complete the request so make sure you check for that before attempting to use the returned variable and assuming you actually have some html to work with.
code :
$html = file_get_html($website);
if($html === false) {
  header('Location: https://test.com/login/display/error_message.php');
  exit;
}

// You can now work with $html string from here onwards.

like below fixes the issue You can create a mapping from HTTP result codes to specific error handlers in your web.config:
code :
<customErrors mode="On" defaultRedirect="~/Error">
  <error statusCode="401" redirect="~/Error/Unauthorized" />
  <error statusCode="404" redirect="~/Error/NotFound" />
</customErrors>
public class ErrorController
{ 
        public ActionResult Index ()
        {
            return View ("Error");
        }

        public ActionResult Unauthorized ()
        {
            return View ("Error401");
        }

        public ActionResult NotFound ()
        {
            return View ("Error404");
    }
    }
public ActionResult Test ()
{
    throw new HttpException ((int)HttpStatusCode.Unauthorized, "Unauthorized");
}
[Authorize (Roles = SiteRoles.Admin)]
public ActionResult Test ()
{
  return View ();
}

or

resources :users do
  member do
    get 'verify'
  end
end

Does that help Put Exit Sub just before the beginning of your error handling code like so:
code :
Exit Sub

ErrHandler:
            MsgBox "Field Description in Config tab not listed on report - please check parameters"
            Exit Sub

hope this fix your issue If the handler output tells you about the failure, you can put together a nice bit of error handling with the ignore_errors and register keywords.
Set your handler not to end to fail and end the play when it gets an error code back, but to register the output as a variable:

Any of those help If you are looking at a pure sling implementation then you can customise the default error handler as per the document:
