Needed Help in PHP?

I have the following error messages in apache logs :

Code:

[Sat Nov 21 14:25:12 2009] [error] [client 10.14.236.140] PHP Warning:  fgets(): supplied argument is not a valid stream resource in /var/www/notice.php on line 70, referer: http://<IP>/notice.php

any idea what is this all about?

Hi,

Open /var/www_81/watch2.php in an editor, copy what's on line 70 and post it here. What's the program you're trying to run through apache when you get the error? Is it something you coded or did you get it from the web? If you got it from the web what is it?

Kind regards,

Eric

Lemme explain you few things Eric..
I have those rrd and log files under /home/john/gra.
Whenever I browse to http://<IP>/filename it opens up:

All the output shows 0.00.
I wonder it was permission issue but I have put john and apache in same group.

No clue whatsoever what might be wrong, but then again I'm not the PHP Guru neither. Someone will have a look soon, I'm sure.

Kind regards,

Eric

A few comments.

I can't see what the each(handles);statement is doing (line 66), I'd remove it unless you can explain why it is there.

The earlier block of code (around line 57) sets up the file handlers but doesn't check that they are working correctly. If the fopen() failed then it will return false, it should also raise a warning.

PHP Code:



if ($_GET['mode']=='row') {
   $handles = array();
   foreach ($files as $log_file) {
      $fh = fopen("$base_dir/$log_file",r);
      fseek($fh,0,SEEK_END);
      $handles[] = $fh;
   }

and where does the close brace for the first if occur?

EricTra ...Can yu hint me what generally causes this error:

Code:

fgets(): supplied argument is not a.....

graemef · 11-21-2009, 04:26 AM

It is expecting a handle to an open file, so that it (fgets) can then read data from this file. The block of code above this opens the file, but it never checks to see if the file has been opened successfully.

EricTRA · 11-21-2009, 04:27 AM

Have you looked at what graemef posted? He might be on to something. Also have a look a this. Like graemef states, the file opening doesn't get handled completely when failing what might result in this error.

Fix what graemef indicated and try again.

Kind regards,

Eric

May I know which file its trying to see?

your_shadow03 · 11-21-2009, 04:30 AM

graemef..What line I need to modify?
Can yu pls dictate the same?

graemef · 11-21-2009, 06:05 AM

As a starter change:

PHP Code:



if ($_GET['mode']=='row') {
   $handles = array();
   foreach ($files as $log_file) {
      $fh = fopen("$base_dir/$log_file",r);
      fseek($fh,0,SEEK_END);
      $handles[] = $fh;
   }

to:

PHP Code:



if ($_GET['mode']=='row') {
   $handles = array();
   foreach ($files as $log_file) {
      $fh = fopen("$base_dir/$log_file",r);
      if ($fh === false)
         echo "Failed to open file $base_dir/$log_file";
      fseek($fh,0,SEEK_END);
      $handles[] = $fh;
   }

By the way your concern about permission could be the problem (Post #5). You need to make sure that the Apache user has access to not just the files but the path to the files. A common problem would be that it doesn't by default have access to the directory /home/john/

No I tried changing the code ..
