Hi,
Hi
what is not working in this code?
That's how I see it
?
$defaultpage = http://lom.game-host.org/uploads/erik/;;
// yes the isset is ok here
If(!isset($page)) {
$page = one;
}
if($page == one) {
// as far as I know echo is all low case written but maybe it's not a
must in all instalations
echo htmlheadtitlePage One/title/headbodyIt
works!!bra href=\ . $defaultpage .
index.php?page=two\Nice.../a/body/html;
}
// else space_here if, not elseif !
else if($page == two) {
echo htmlheadtitlePage Two/title/headbodyThis is page
.$page. -- a
href=\.$defaultpage.index.php?page=\;D/a/body/html;
}
// instead of || (and instead of or) here to have the opposite!
else if( ($page != one) ($page != two) ($page != NULL) ) {
echo htmlheadtitleUndefined!/title/headbodypage isn't
defined correctly!/body/html;
}
if($page == ) {
Echo brbrbrbrbrbrbrbra href=.$defaultpage.Main
Page../a;
}
?
Thank you,
You're welcome :)

Okay.. I was just wondering; What's the difference between = and ==? Would
it matter if I changed them? It seems as though if I put = instead of the
=='s, it comes up ONLY page two no matter what $page equals, and if it's ='s
instead of =='s, then it comes up with only page one no matter what $page
equals.
It's a *BIG* difference!
Because single '=' means that whatever stands at the right side of the
'=' should be assigned to whatever stands at the left side,
ie.
$a=5
doesn't compare if a is equal 5, only assignes the variable 'a' it's
value which will be 5 after this code
so if You write
if ($a=5) {...}
it will always be executed (therefore else isn't executed), as
assignment always returns true :]
so when using 'if' You always need to do
if ($a==5) {...}
unless of course Youd want to do an assingment and some code, but then
why not do
$a=5;
...
? :)

Re: [PHP] What software do you use for writing PHP?
Jeff McKeon napisał(a): Hey all, Forever now I've been using Frontpage for all my web work including php. I'm sure there's better software out there that is more suited to writing and editing PHP pages. What do you all use? I use Bluefish, it's a very nice GTK+ based editor, with all types of code highlightning (html, php, c/c++, pascal, java, python are just a part of it). And that's pretty much all the features of it I use, maybe also the well written replace method. Besides that I use it as a typical text editor, I'm not too keen on template's. -- 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, 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($file)) echo Is writablebr; else echo Isn't writablebr; works when I run it as root, from the shell (php script.php), but when it's run from the server, it doesn't. I mean, the output _IS_ in _BOTH_ cases Is writable but that doesn't change a thing, cause when executed from the apache, it just creates an empty file without content. The other thing I was supposed to check was stat($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)
Brian V Bonini napisał(a): You are saying: From the CLI you can write to a file all day long, no prob. Yes, the shell command php test.php works fine when executed as root (any other user has the same problem as from the web) From the web, if the file does not exist it is created, however, no content is appended to it. Furthermore, IF there is content in the file it can be appended to via web, but if it's an empty file it will not get written too. Am I following correctly? Exactly, as strange as it sounds, it's just like it is. And another thing, the whole instalation was working perfectly for the past month or two, and now (friday-saturday) suddenly the above symptom have appeared. No config changes, no updates or anything else I could relate was happening on the server, and there is no info in the log files on this behaviour, the is_writable says it is writable. The safe mode is disabled. Hope this tells You something, and gives You an idea on how to solve this. -- Best wishes Łukasz Hejnak -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Brian V Bonini napisał(a): What does 'df -h' say on your system? !!! The simplest of all is the most unforseen.. 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.

[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
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). -- Best wishes Still hoping for Your help Łukasz Hejnak -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
