Blank white page

MasterACE14 · April 26, 2009

One user out of about 300 on my website is getting blank white pages on a few different pages on my website when logged in. The page is completely blank and white, however the code is still executing because the database values do change as they should when forms are submitted.

Everything works fine for all the other users, so I can't see how it could be a parse error, warning, notice or mysql error.

I'm at a total loss.

Any help is appreciated.

Ask the user for details on his browser/OS and exactly what he types in / buttons that are pressed.

If it goes fine and only one person is seeing white page he/she is obviously either doing something differently or use a setup different from the rest.

Also ensure that you're using valid HTML, as I suspect it's some browser rendering bug caused by buggy HTML.

Turn on error logging to a file and see if something comes up.

ToonMariner · April 26, 2009

Application logging really helps out when you are bug fixing a live site.

start recording browser info as Aexia suggests. You could also cache the pages being served out to this user - opening them up in your own browser to see if you can replicate (you should perhaps use some VM ware to truly replicate their environment).

In this case as only one user has an issue just log based on their userid...

Post back if you need tips on what to log.

in the error_log file, everytime my user encounters a white page. This is what is logged in it.

any idea's on how to fix this?

cheers.

Fatal runtime errors mean fatal. Execution stops at that point, php executes the page destructor cleanup code and stops.

It would take knowing what your code on that page is doing. It either requires more memory than is available or it contains a logic error that continually consumes memory in a loop until all available memory has been used.

MasterACE14 · April 28, 2009

any particular reason why only one user would be getting this? and not all users?

Daniel0 · April 28, 2009

That's difficult to say, but try to look at where the log entry says the error occurred. Maybe that'll help you.

It would take knowing what your code on that page is doing.

ToonMariner · April 29, 2009

you MUST sanitize any data you collect from a user. If this is particular to one user check and see what is unique about that user - it could be something stored in the session like a character that causes the problem...

Memory allocation problems are often caused by recursive execution of code - it could be that this one users is experiencing this - maybe an include is cycling by calling a page that is already been called.

if possible switch and require/include to require_once or include once.

You could get the users details and test locally - debugging script by inserting various echo statements and exit(); to stop execution at strategic points (not the best way to debug but if you don't have any other tool available and don't want xdebug then it could be good for you - I learn't a fair bit debugging this way in the early days )

good luck and keep posting back any updates.

It appears several more users have been having the same problem, and have only just reported it now. The problems only seem to have started when I released the next version of my game.

So the past few days I've been running through my code seeing where I may have slipped up with a loop, undeclared variables, PHP Warnings the works.

I came to the conclusion that the out of memory error may have been caused by the HTML compression I added.

// compress HTML
//ob_start("ob_gzhandler");

after commenting it out I now only appear to get the rare out of memory error.

However there is another error now, that I just can't find what is causing it.

The line where the output is occurring is a user written function. That function is causing some output, either an error message or it is deliberately outputting something. You cannot have any output before a header().

deth4uall · May 1, 2009

I have had a problem similar to this before... put

<?php
exit;
?>

after the headers, this will stop the other parts of the displaying info from loading when you declare a header...

MasterACE14 · May 1, 2009

adding exit; after header's and changing the variables that are divided by zero to one seems to have fixed attack.php

And there is no Out of memory error's showing up in the error log for today. I shall post back here if the problem arises again.

Thank you everyone for your assistance and patience.

Regards, ACE

ah the blasted things back to haunt me.

[01-May-2009 21:17:08] PHP Fatal error: Out of memory (allocated 44564480) (tried to allocate 2097152 bytes) in /home/eliteace/public_html/realmbattles/vsys.php on line 379

I haven't changed anything in that file for 150 lines either side of line 379.

Would a increase in players contribute to this problem?

MasterACE14 · May 4, 2009

A new update.

in the error log I am getting 4 of these in a row...

[04-May-2009 03:34:27] PHP Fatal error: Out of memory (allocated 45350912) (tried to allocate 35 bytes) in /home/eliteace/public_html/realmbattles/vsys.php on line 379

and then several of these are coming up after it...

[04-May-2009 07:19:15] PHP Warning: array_rand() [<a href='function.array-rand'>function.array-rand</a>]: First argument has to be an array in /home/eliteace/public_html/ads/ads.php on line 36

although the time difference is of a fair size. Is it possible that the problems are linked?

MasterACE14 · May 5, 2009

it was constantly line 379. But there has been very rarely these lines...

line 398 has been coming up more and more over the last day.

What exactly does this script do? It seems like it goes into an infinite loop sometimes or loops that take too long and eat up memory.

Does it deal with images at all? How about creating complex arrays, or uses a bunch of loops that are done dynamically....We do not have the insight to really help you out with this error.

MasterACE14 · May 5, 2009

  function getWeaponArray1($Weapons,$WeaponCount ){
	$weaponAW=split(";",$Weapons);
	$weaponAWC=split(";",$WeaponCount);
	$k=0;
	for ($i=0;$i<count($weaponAW);$i++){
		for ($j=0; $j<$weaponAWC[$i] ;$j++){ // line 2177
			$weaponA[$k]=$weaponAW[$i];
			$k++;
		}
	}
	return $weaponA;
  }

 function getStrikeAction($user)
  {
      global $conf;
      $num = 0;
      $trainedCount = $user->trainedAttackSold + $user->trainedAttackMerc;
      $untrainedCount = $user->untrainedMerc + $user->untrainedSold;
      $weaponA1 = getUserWeapon($user);
      if (!count($weaponA1) && !$trainedCount)
          return 0;
       $k=0;
       for ($i=0;$i<count($weaponA1);$i++){
       for ($j=0; $j<$weaponA1[$i]->weaponCount ;$j++){ // line 398
       $weaponA[$k]=$weaponA1[$i];
       $k++;
       }
       }

neither function has been altered since it was first written over a year ago, and the problems only recently started occuring.

premiso · May 6, 2009

So it is a loop causing issues. I would test those loops and make sure that they are as efficient as they can be.

Add some debugging in there so you can see how many times the loop actually runs etc and what type of content is being pulled out. As that is your issue.
