Wow. that's it ;) I NEVER EVEN Imagined to check for that, in fact that _IS_ the thing. I feel so totaly stupid right now, I checked everything except this, although I think the fwrite _SHOULD_ return false on this, and it should print out an error saying that there's no space available.. The thing is that my system has a few partitions, one of them is the one containing wwwroot. I never even once got a msg that the filesystem is full, as most of my operations (recompiling etc.) were conducted on a seperate partition. Now I see it and can take it all together, as there is one script doing backup of the www sites, it does so every night, and that was the thing that made it full.

Re: [PHP] Problem with the fwrite function (not as simple as it sounds though)
Hello again, here's some more extra info on my case that came out while Suhas Pharkute was helping me find a resolution: So the safe-mode is off, that's for sure, I turned it off at compile stage. I delete the file after each run of the script, the folder where the script is located has 777 permissions and the ownership is given to uid 1027 gid 1020, whereas these are the uid/gid set for apache to run with (and it does!). The script: $data="some data"; $file="file.txt"; $handle = fopen($file,"w"); fwrite($handle,$data); fflush($handle); fclose($handle); if (is_writable($file)) echo "Is writable"; else echo "Isn't writable"; works when I run it as root, from the shell (php script.php), but when it's run from the server, it doesn't. I mean, the output _IS_ in _BOTH_ cases "Is writable" but that doesn't change a thing, cause when executed from the apache, it just creates an empty file without content. The other thing I was supposed to check was stat($file); with clearstatcache(); called beforehand. The output of this is: device number: 777 inode number: 1142470 inode protection mode: 33188 number of links: 1 _userid_of_owner:_1027_ groupid of owner: 1020 device type, if inode device *: 0 _size_in_bytes:_0_ time of last access (Unix timestamp): 1132482491 time of last modification (Unix timestamp): 1132482505 time of last inode change (Unix timestamp): 1132482505 blocksize of filesystem IO *: 4096 _number_of_blocks_allocated:_0_ and of course when executed as root: device number: 777 inode number: 1142470 inode protection mode: 33188 number of links: 1 _userid_of_owner:_0_ groupid of owner: 1020 device type, if inode device *: 0 _size_in_bytes:_9_ time of last access (Unix timestamp): 1132482980 time of last modification (Unix timestamp): 1132482980 time of last inode change (Unix timestamp): 1132482980 blocksize of filesystem IO *: 4096 _number_of_blocks_allocated:_8_ Can anybody help me? -- Best wishes Łukasz Hejnak -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Problem with the fwrite function (not as simple as it sounds though)
Hello again, some extra info on my case:
the fwrite is completely fine, when fopen is in 'a' mode!
Thus leading to a temporary workaround like this:
$file = "/wwwroot/file"
$countt = explode(".", fread(fopen($file,"r"), filesize($file)));
$count=$countt[1];
$count++;
$handle=fopen($file,"a");
ftruncate($handle, 1);
fwrite($handle,$file);
fclose($handle);
Now having a file with content in the form:
.15
makes it possible to use the above as a workaround..
but still I need to find out what's the problem here. The counter isn't
exactly the only thing I use fwrite for..
The clue I got is, non-empty files are ok to be written in (appended),
empty on the other hand, are totaly uncool for that.
So using a ftruncate($handle,0); is just as I'd use fopen($file,"w");
(gives the same result).

Still hoping for Your help

[PHP] Problem with the fwrite function (not as simple as it sounds though)
Hello, First of all sorry for my english, trying my best :] The story is: I'm running a small webserver and to monitor the amount of people going trough my pages, I've made a simple counter (storing the data in a text file), no matter the details, the important thing is that it WORKED just the way I wanted it to. Till yesterday evening. Today I noticed that all of the counters, that were modyfied since yesterday, have been blanked. I started looking trough the logs and found a large amount of PHP Warning: fread(): Length parameter must be greater than 0. which was the expected behaviour when reading an empty file. After a while of checking, I got to the fact that something's wrong with the fwrite() function. I've writen a 'test' script only to see if I can write files. When writing to the /tmp dir, all went fine, but when I tried to write to any of the other directories within my $WWWroot the result was an empty file. This is the script: $data="some data"; $file="/wwwroot/file" $handle=fopen($file,"w"); fwrite($handle,$data); fflush($handle); fclose($handle); And as written above, the output was only an empty "" file /wwwroot/file nothing more. I thought about premissions, but after setting the wwwroot a+rwx, setting the owner and group as the same as the apache server works under I got the idea that's not it. I reinstalled the apache and php. Now I'm using httpd-2.1.9 and php-4.4.0 (as a module) but the problem is still there, before I was using httpd-2.1.8, but as I said, the problem appeared out of nowhere, when the server was just running on it's own, without upgrades, patches, config changes, or anything other. In fact all it was doing trough the night was serving the websites and receiving mail. I runned out of ideas. The logs don't show anything related to this. I tried to enable all debug logging, but despite the fact that I'm receiving now 3 times more info on everything else, there's nothing on the fwrite() attempt or related. Can anybody help? If any more data is required on my side, I will gladly cooperate to get the thing solved. -- Best wishes Łukasz Hejnak -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
