"unless they were a majority" is the thing that bothers me. Getting a
majority is hard, take for example the Dutch Politics [1]. Our country
is now led by a parliament of 10 different political parties. Getting
things done now is really hard, because each party has their own goals
and finding a majority is for almost impossible. If all the parties
were strictly following their own will, there would probably only a
handful things done. The only way to get things done now is by making
compromises.
Another example is of course religion [2]. You can see that there's no
majority there. Christianity being the largest with 33%. Even if that
would be over 50%, you won't get peace if you say Christianity is the
only correct religion..

I thought that ^^^ sounded really clever. Care to share your hosts file? ;-)

If it ever was alive, it will die the same way as this thread, after a long
discussion...

I have a very large XML file that I have to process. It's about 7 GB.
Some of the individual elements that I need are larger than 8192 bytes.
I'm trying to write a Stream wrapper class to give me a specific element
at a time, but I keep running into issues with the stream wrapper and
fread, stream_get_content functions.
fread will never return more than 8192 bytes (is that a bug?), so I can't
use that at all. When I use stream_get_content, and pass in 16384, weird
things happen in my stream_read method. If I return 16384 bytes, it gets
truncated to 8192, and the stream_read method is called again and again,
until the total returned is 16384. Normally, stream_read is called twice
in this case (since it "returns" 8192 both times).
This really screws up what I'm trying to do with this stream wrapper.
Admittedly, I don't know much about stream wrappers. This is my first
one, and I can't find much relevant documentation on them. But it
doesn't seem like it's working correctly to me. If I ask for 16384 bytes
with fread, shouldn't it give me 16384 bytes? And if I return 16384
bytes when I use stream_get_contents, shouldn't it return 16384 bytes the
first time?
Thanks for any help.

You could just use the XML Parser (SAX) as it doesn't require loading
the entire document into memory:

I'm not sure if I'm missing something here, but PHP manual clearly
states that when using fread on streams you need to call fread in a
loop to get the amount of bytes required, as it will only return 1
packet at a time (TCP/IP are usually 8192 bytes).
(Though Adam is probably right that the builtin XML parser is the best way)

Sorry, I just realized my replies were going to email instead of the news
group.
I'm going to try upgrading to php 5.4 so I have access to this:
http://php.net/manual/en/function.stream-set-chunk-size.php
And see if that fixes some of my problems. Thanks for the suggestions.

--- Begin Message ---
Followup:
I installed php 5.4.7 and tried using stream_set_chunk_size. It is now
working as expected with stream_get_contents.
Here is my stream wrapper class:

Here is how it is used:

Hope that helps someone else that is having issues with stream wrappers.

And so Dutch governments only last short periods of time, and it takes a long
time to create a coalition. This is why Proportional Representation is such a
bad idea. Better to have strong government with a clear mandate, and if you
don't like it, vote it out next time.
By the way what does any of this have to do with PHP? Nothing, I think.
