fopen

toshog

problem:

$file = "looooooooong.url.string.com/test?looooong=very%20long%20string";

fopen gives me this on the browser window:
failed to create stream: File name too long in /path/to/file.php

ok.. what are the possibilities to open a file from another machine that has a very long variable string passed to it?

You cannot open a file with a query or what you have called it a string. It must be e.g. index.php not index.php?text=long etc

i'm not sure if i'm following....
so far i've been able to do something like this:
$file = "http://www.mook.com/interface.jsp?id=666&somestuff=stuff&etc=etc.....

if (!($fp = fopen($file, "r"))) {
die("blop");
}
else{
echo "yey";
//do something with this file....
}

the main issue here - as the error says - is that the url this time is to long. one of the values of the variables passed to the java interface is an xml document like this:
...&xml=<root><subroot>1</subroot><subroot2>2</subroot2></root>
but much larger.... this is supposed to work because that's how it's advertised on the site i'm trying to pass the xml value to...

my question is how can i get this file if not with fopen?
i looked at the php.net....

thank you....

ok... i red some more but it doesn't say anywhere - Appendix I on php.net either - how long should the file name be...
i'm considering to use fsockopen but i assume that will be slower then fopen because fsockopen goes through the system and fopen does a direct http request....

is there a limit on how long the filename requested through fsockopen should be?
what is the limit for fopen? why?

can somebody please share thoughts and maybe advise...

thank you..

Some problems I see with the original URL are:

(a) It doesn't mention the protocol - no "http://" - so how's PHP to recognise it's a URL?
(b) If it is a URL, then values in the query string should be urlencoded
(c) The maximum length of a URL is dependent on the server the URL is being sent to. A typical maximum is 255 bytes (ASCII characters). The relevant section of the HTTP specification is 10.4.15.:

10.4.15 414 Request-URI Too Long

The server is refusing to service the request because the Request-URI is longer than the server is willing to interpret. This rare condition is only likely to occur when a client has improperly converted a POST request to a GET request with long query information....

The short answer is to use fsockopen() - it will be faster. After all, fopen() will have to go through the operating system to get to a socket to make its request as well (how else is it supposed to make an http request?) - and it uses fsockopen() to do that. Means more work for you, but that's because you'll have more control.

thank you, Weedpacket...

(a) - i do have http(s) in front of the url - i didn't put it in the post - my mistake, sorry...
(b) - for the same application so far i've been using fopen without any urlencoding and it is working fine.... but i'll consider encoding it....
(c) - if the maximum length depends on the server the url is beeing sent to, then how come the php (fopen) on my server is giving me the error - not the remote server? also the service i'm sending the query to, in their tutorial, the example they give is a url with the same length i'm testing with....

if, as you say, fopen uses fsockopen, would using fsockopen with the same url produce the same error?

thanks....

ok... this is getting a little bit rediculos...

codeline:
$fp = fsockopen ("ssl://www.foo.com", 443, $errno, $errstr, 30);

it's confirmed that the ssl port on the remote server is 443.

from phpinfo.php on the same machine:
'/configure' '--with-apxs=/bin/apxs' '--with-mysql=/mysql' '--with-openssl=/usr/local/ssl'
i just recompiled php.... again....

compiling error from the browser:

Warning: fsockopen() [function.fsockopen]: no SSL support in this build in /path/to/file...

why?

I'm also having same kind of problem with fopen-function while opening a link to another server to get some information by xml.

The fopen-function works normally when I have the code in the default-page, but when I do the same with a function-call to a included php-page I'll get the error.

Please, could anyone give a hint to solve my problem, because I'd like to have a different function-file to keep the code more readable!
