It was added a long time ago, yes, and it is indeed documented (as
already noted in this thread). I'm not sure which copy of the manual
Ash is reading from, but the one I'm looking at documents this
behaviour. And it's right there in the PHP source code (and easily
testable, as you have shown).

Re: [PHP] fread() behaviour
On 20 Nov 2008, at 01:29, Rene Fournier wrote:
I'm trying to understand something about fread(). I'm using fread()
on an incoming socket stream that will send, for example, 26630
characters:
while ( ($buf=fread($read[$i], 8192)) != '' ) {
$sock_data .= $buf;
usleep(1000);
echo ".";
}
echo ",";
As soon as the socket client sends the data, immediately the server
will echo:
Then wait nearly a minute, and echo:
,
So my question is, why does fread wait if there is nothing more to
read? Shouldn't it return immediately? (That's what I want.) And as
for the delay, it's there so that if the incoming data is a little
slow, it has time to catch up with fread. Thanks.
As Craige already mentioned, fread will read bytes until it meets an
EOF so unless the other side sends one or closes the socket fread will
wait for the number of characters you've asked for (8192) or a timeout
(which is the delay you're seeing). In other words it's not detecting
the end of the data, it's just timing out waiting for more.
You ideally want to have the other side tell you how many bytes it's
going to send. If you can't do that then hopefully the data you're
receiving has some sort of structure so you can check the incoming
data for some terminating string. If not then you've got a problem
that can't be reliably solved. You could mess around with the timeout
and/or make use of functions like socket_select to check for waiting
data, but what you'll end up with will be problematic on slow
connections and generally unreliable.

Any reason why in_array is returning TRUE when one has a 0 value on
the array ?
That's weird, 5.2.6 does the same thing. There's actually a comment
about this on the in_array manual page from james dot ellis at gmail
dot com...
Be aware of oddities when dealing with 0 (zero) values in an array...
This script:
It seems in non strict mode, the 0 value in the array is evaluating to
boolean FALSE and in_array returns TRUE. Use strict mode to work
around this peculiarity.
This only seems to occur when there is an integer 0 in the array. A
string '0' will return FALSE for the first test above (at least in
5.2.6).
So use strict mode and this problem will go away. Oh, and please read
the manual before asking a question in future.

Alain, you've been on this list long enough to know that "it does not work" is not enough information for people to be able to help you. Firstly there is no need to serialise anything going into the session. Secondly I assume you want to store objects not classes. Thirdly there is no reason why it should not work, but there are some caveats you need to be aware of... * The class definition must have been loaded before session_start() is called, otherwise you'll end up with an object of type stdClass rather than your class. * Resources stored inside the object must be cleaned up in __sleep() and can be recreated in __wake() as they will not be stored in the session along with the rest of the object.

I currently have it like this:
if you've got it working don't change it :)
but to explain:
it is possible to send through an array of data from a form, to do this
you place multiple elements with the same name followed by [] in the form..
so
.. (our first select)
... (our second select)
when you do this php will recieve the BannerSize as an array.. so in the
above scenario
$_POST['BannerSize'] will contain an array as such:
array(
0 => "300x250", #whatever was chosen in the first select
0 => "88x31-300x250" #whatever was chosen in the second select
);
now in the script you originally posted, php was using
implode($_POST['BannerSize'] , ',' );
this function was basically taking the array values and combining them
together as a single string.
the problem was that if you're form had (no
brackets) then php didn't receive and array of info in
$_POST['BannerSize'] - and thus when it tried to implode the array, it
broke, as there wasn't an array within :)
now, most got confused because most people write implode with the
parameters the other way around, and they thought that was the error, so
kind of confused things. [and because you posted it about 5 times under
different names which didn't help ;)]
in short:
if you were using 's then you'd be wanting
to implode the data as it's an array you're recieving
if you're using as you currently are, then
you can forget about all the implode etc.
the ideal fix would have been to make the php code accept either and
detect if it was an array or not being passed by replacing the original
code:
if (isset($_POST['BannerSize'])){$BannerSize =
implode($_POST['BannerSize'],',');} else {$BannerSize = "";}
with this new code:
if (isset($_POST['BannerSize'])) {
if(is_array($_POST['BannerSize']) ) {
$BannerSize = implode(',', $_POST['BannerSize']); //in right order..
} else {
$BannerSize = $_POST['BannerSize'];
}
} else {
$BannerSize = "";
}
which first checks if banner size has been sent at all,
if it has is it an array? [if yes implode it, if not just pick up the
value sent]
hope that helps!

good stuff from Stut & Craige ... I just wondered, Im pretty sure that the
usleep(1000) is completely superfluous. fread() will read to the buffer length
or EOF regardless of how slow the stream trickles in (obviously it may timeout
if nothing trickles in for ages but that's a different issue and not solved
with a usleep() AFAICT).

[PHP] Model Web Site
My prime hobby is photography and the next is web site building. So now I have a young model (18+) asking me about getting a web site. The idea is members can see content, that will include, photos, her blog and a discussion forum. I like the idea of building it, but it includes a lot of things I have no experience in. Can someone point me to documentation/tutorials/scripts or anything that might help. I don't want a turnkey solution. I want to learn how to do this. Thank you!

Stephen, The whole thing could be built pretty quickly using existing open source systems such as phpBB3[1] and Gallery[2] as a core. Then it's a matter of putting up smaller additional scripts to link your other things together. 1: http://www.phpbb.com/ 2: http://www.nukedgallery.net/ Just some examples, of course. There are literally thousands of options, including building your own or hiring someone to do it.

What about using the === and !== comparisons to compare and make sure
that 0 is not giving a false false.

Re: [PHP] Model Web Site
As Daniel mentioned, I would recomed building it upon an existing system. I've seen whole sites custom built around PHPBB. This might be something you want to look into. Google for PHPBB programming tutorials; it's pretty well documented. I think it's your best bet if you don't want to spend forever building it from the ground-up. PHPNuke might be a good option too, but I never liked it myself. It's all provided out of the box though. - Craige -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I wouldn't consider it weird; it's just how PHP handles loose type
comparisons. I would certainly agree that it's not terribly obvious
why it happens, though. :) That said, it's consistent with PHP
behaviour.
James Ellis almost got it right in his note. As I already noted, it's
not because of a conversion to boolean FALSE, but a conversion to
integer 0. You can test this by substituting FALSE for the 0 in the
array in the example and trying it.

[PHP] reading XML
Hi all, I have a script that I call with CURL and get an XML response with a few parameters. I need to be able to read that XML but not sure how to. I know of simpleXML but the server is php4. Would xml_parse be the thing to look at? What is the simplest way to accomplish this small challenge? Thanks in advance.
