I have seen this more then once, I know that there is no service running

It's only with a few ip-number I have this problem.
if ($fp = fopen('https://81.23.227.9', 'rb', false)) {
echo ok;
} else {
echo failed;

I don't think this is a php problem, just load the url up in a browser
and you'll see the same, appears to be a misconfigured server at the
otherside - probably confused about not being passed a name based host
header in the request.
Perhaps concider moving to fsockopen or stream_socket_client with
timeout parameters to solve your issue.
Many Regard

If it's a busy server, you may be running out of TCP connections... If PHP can't open ANY connection at all, it can't do a DNS lookup, and it would fail very fast, as it's hitting an OS limit/cap on the number of connections and not even getting to try to talk to the Internet.

[PHP] Re: fopen
Hi,
yes, there could be some problem with your code. But it depends on what
are you trying to archieve.
If you are trying to put whole file to database, there is no reason to
use fgets function. Just use $buffer=file_get_contents($filename); and
put the buffer into SQL. No reason to read it line by line using fgets.
The whole file will end in memory in the SQL section, so it doesn't
matter ho you read it.
If you want to process huge file line by line, it's really good idea to
not put whole file to memory (using file_get_contents) but to read it
line by line using fgets, process every line and forgot it. The file
could be very large and you still need only very small memory amount.
And there can be problem you are saying.
What if there is some line longer than 4096 bytes (or some bigger
limit)?? You can solve it simply using code like this:
$dataFile = fopen( $filename, r ) ;
$buffer = ;
while (!feof($dataFile)) {
$buffer .= fgets($dataFile, 4096);
if (strstr($buffer, \n) === false !feof($dataFile)) {
// long line
continue;
}
echo $buffer;
$buffer = ;
}

Your application, as it stands now, has a race condition between the open

Probably.
Maybe.
If $filestr is small enough, the Linux OS has locking built-in. Windows
may or may not (and I don't care enough about Windows to remember, much

chmod($defaultfile, 666);
http://php.net/chmod
has examples that tell you exactly why this is wrong...
666 is decimal.
The 666 you want is Octal.
They ain't the same number.
What does the at_sign mean at the start of this line?
@ $results = fopen($datafilename, w+);
@ means you are IGNORING any errors this generates.
It's usually a really bad idea unless you have some more code for error
checking.
if (!$results) { die (Our results file could not be opened for writing.
Your score was not recorded. Please contact the person responsible and
try again later.); }
flock($results, 2); #lock file for writing
fwrite($results, $filestr); #write $filestr to $results
flock($results, 3); #unlock file
fclose($results); #close file
This is an incorrect way to try to flock a file for writing.
You should:
1) Open the file for READING.
2) flock that file handle, so only YOU have access to that file.
3) Re-open the file for WRITING, now that you have control.
4) Write your data
5) Release the lock.
Your application, as it stands now, has a race condition between the open
for writing and the flock, which sooner or later, WILL bite you in the
ass.
Probably.
Maybe.
If $filestr is small enough, the Linux OS has locking built-in. Windows
may or may not (and I don't care enough about Windows to remember, much
less look it up). FreeBSD and other OSes may or may not also have locking
at OS layer. I wouldn't rely on it, though, since it's trivial to do the
5 steps above.

Re: [PHP] Re: fopen
Hi,
W+ does not work either.
I have resorted to adding a blank, 0 byte text file.
But it needs chmod 666.
Interesting, I add this line:
chmod($defaultfile, 666);
and it send back an illegal error, but it appears to work anyway - the data is
written!

@ $results = fopen($datafilename, w+);
try $results = fopen($datafilename, w+);
$defaultfile = /home/johj2201/public_html/ffmail.txt; #default file to write

chmod($defaultfile, 666);

Convert to database. Your hair and your aspirin intake will thank you. Even though the r+ option is supposed to put the pointer at the beginning of the file This is correct and is working. and add to it as opposed to overwriting This is simply not correct! r+ does not do any magic.

But if the files are big as you claim, then neither of these options is really going to be all that fast. Convert to a database. One *other* option is to store each article in a different file with the date as the name of the file, and then you can snag the new articles fairly quickly by using the file name as the key...

If you are worried about this, you should probably use a database which will take care of this for you... It is possible to use http://php.net/flock to lock the file, pretty much like the example in the manual, and then 4999 users will have to wait until the one editor is finished... You'll still need to be sure that those 4999 users then get the most current version before they start editing, so you'll need to check what they have now with what's in there before you let them blindly replace it...

Re: [PHP] Re: fopen, fread
Yeah, filesize() does not work with urls. Suggested file() and implode() earlier for this task and didn't mention fgets() as it may be appropriate here as well. http://www.php.net/fgets http://www.php.net/file Both manual entries have examples that do exactly what you want, Put a url contents into a string. fgets() is nice because you don't have to gets the entire file, sticking a break; in there during a match can be uber cool :-) If this is being done locally then of course don't go through http:// ... Regards, Philip Olson On Sun, 23 Sep 2001, Simon Roberts wrote: Check the value of filesize($fileName). It's probably not working - either because PHP doesn't support it with URLs (likely) or that it's can't get the length from the webserver (less likely).

Hey all. I'm trying to do a fopen for reading on many different sites and web pages. However, I have found that many webpages can not be FOPENed at all. For instance, one such example would be http://www.800.com/prod.asp?P=5261 I do not understand as I can read from numerous other sites. Why can I see the above site and others in Internet Explorer and Netscape, but PHP is not able to read from that file? And yes, I can read from many other ASP, JSP, and PHP pages, so this is not the problem that I know of. Any help appreciated.

Re: [PHP] Re: fopen a URL with = in it
So you're saying that I should be able to pass the = sign in just fine into the fopen call with no errors? I understand what you mean that if = was what the variable was defined as, then THAT is where I'd use urlencode ;) I wasn't too sure about that, but now I am. Quite odd that it reports errors then when passing in an = sign. Perhaps PHP does not like to load url's like that.. You would only want URLEncode if thething had the = in it as part of the data... http://whatever.com/foo.php?operand=; . urlencode(=) might be a URL for math geeks to talk about the = sign :-) -- WARNING [EMAIL PROTECTED] address is an endangered species -- Use [EMAIL PROTECTED] Wanna help me out?

Could it be a bug in PHP? Using the fopen function (or even the file function), I want to open a web page for read. Sounds easy? Well, say I want to have an = sign in the URL.. well that is where the problem comes. I have tried things like this: $eq = urlencode(=); $URL = http://www.something.com/file.php?thing.$eq.thething;;; I have tried many other combinations as well.. the problem is this: when PHP calls fopen(), it does not allow the = sign in the variable passed in. So I figured I should escape it.. fopen(http://www.something.com/file.php?thing\=thething,r;;); But that did not work either. It allows me to pass it in, but then it tries to open the literal \= in the url, which of course doesn't exist. The url has just an =. I thought encoding the whole or part URL would work. well it loads the page, but the page itself doesn't recognize the encoded = sign as being an = sign.. Bah! Anyone have any ideas.. ?

[PHP] Re: fopen(fd, w) doesn't work?
for the first part, make sure that you have write permission to the directory specified, and for the second, you can't open a file for writing from a remote location.
