Hi,
I'm trying to write a stream wrapper that will be used to let users
download a file only once.
I'm confused as to what function definined on the php definition page
for stream_wrapper_register I need to use. I'm guessing that stream_eof
will be important.
What about stream_close?
Thanks

You'll need most of them, more than likely. stream_open, stream_read,
stream_close, stream_eof at least.
stream_wrapper_register('onetime','onetime');
class onetime
{
var $fp = FALSE;
stream_open($path, $mode, $options, $opened_path)
{
//Perform check for only one download
if($this->fp = fopen($path,$mode))
{ return TRUE; }
else
{ return FALSE; }
}
stream_read($bytes)
{ return fread($this->fp,$bytes); }
stream_eof()
{ return feof($this->fp); }
stream_close()
{ return fclose($this->fp); }
}

I've got a couple of ideas, but I really think you're making life too
hard for yourself. You might want to rethink what you're trying to do
rather than creating a clunky solution.
Anyways, on with my ideas...
* Send the file as the first part of a multipart response. The second
part would be an HTML page which uses Javascript to close the window.
I have no idea if this would work.
* I'm guessing the window you want to close was created by the main
window. If this is the case you could use Javascript to start the file
downloading in the main window from the popup and then close the
popup. e.g. opener.location.href = 'thedownload.file';
window.close();. This should work.

Hi,
I'm not sure I understand why you would use instanceof on $this. Try
this code:
Kind of complicated (so probably not the best way) but I have objects
I'm creating with a factory method - and all of these objects *should*
be extending a parent class. It's in the parent class where I'm using
$this instanceof __CLASS__ and alternatives are welcome. I thought is_a
was being deprecated (correct me if I'm wrong) ?
Hi,
is_a is replaced by instanceof. I don't understand why you would need
to check the class of $this anyways. Are you calling methods from
classes that are not parent classes? If not, then you can be sure that
$this is always a class in the hierarchy. Maybe a bit more code is in
order to explain the problem.
why not just do
if ($this instanceof Test)?

Thanks for the response.
I have this:
$DateAdvertised=$row["DateAdvertised"];
$DateAdvertisedBroken = explode("-", $DateAdvertised);
So I can easily use this in my table:
$result[DateAdvertised]
But not this for some reason:
$DateAdvertisedBroken[n]
Any ideas...?

Following the query I have this:
<?php while($result = mysql_fetch_array($query))
{
$DateAdvertised=$row["DateAdvertised"];
$DateAdvertisedBroken = explode("-", $DateAdvertised);
Then a little while later this:
$DateAdvertisedBroken[2]-$DateAdvertisedBroken[1]-$DateAdvertisedBroken[0]
which returns nothing, but should as $DateAdvertised does... :|

You are subtracting the values???? Presumably you really want to concatenate
the values, sepearated by dashes, as a string?

This should be like this
<?php while($result = mysql_fetch_array($query))
{
$DateAdvertised=$result["DateAdvertised"];
$DateAdvertisedBroken = explode("-",
$DateAdvertised);
}
Script is fetching the data row in $result array but
using $row for it.
It is not possible.

The extensions may rely on other .dll files to be enabled. Check the

Download the binary Package (zip file) where you gonna find these libraries
mySQL:
======
Copy the "libmysql.dll" in your System32 folder. This is needed for
php_mysql.dll to load.
CURL
====
[from the manual] Note to Win32 Users: In order to enable this module on a
Windows environment, you must copy libeay32.dll and ssleay32.dll from the
DLL folder of the PHP/Win32 binary package to the SYSTEM folder of your
Windows machine. (Ex: C:\WINNT\SYSTEM32 or C:\WINDOWS\SYSTEM)

You really should take the time to search around on Google about SMTP
servers (Mail servers). If you want to send mail, either have access to a
remote SMTP server (your ISP *has* to have one) or install one yourself on
your computer. I have no clue what your OS is but if you're using
Linux/Unix, go search for sendmail, Qmail or Exim. For windows, Exchange.
I think this isn't the place to ask about setting up an SMTP server.

I am agree with Catalin about "no property is created", that __set() and
__get() create "virtual" property.
But, for the programmer, property which was set whith __set() and
__get() ARE REAL, and must be use as real property.
Conclusion : if php provide __set() and __get() to simulate object
property, all function in the language must interact with them as usual,
even if property are not real.
So, an isset() call on a property wich was created witch __set() MUST
return TRUE, and not FALSE.
And __set and __get functions are very interesting.
Imagine a session object, for example :
class session
{
private $id = '';
private $data = array();
...
function __get($dataName)
{
if (isset($this->data[$dataName]) == true)
return null;
else
return $this->data[$dataName];
}
function __set($dataName, $dataValue)
{
$this->data[$dataName] = $dataValue;
}
}
and you can do something like that :
$session = new session();
if (isset($session->idUser) == true)
$idUser = $session->idUser;
else
#http location on a login page
And in login page :
$session = new session();
$session->idUser = 'aUser';
But in this case, isset() MUST RETURN A GOOD RESULT, true

Greetings,
I'm using PHP v4.3.7 on my Windows 2000 Server machine with IIS 4.0 as web
server. When I tried to test a simple client server app (server.php and
client.php - attached), I get the warning message below: -
Warning message
===============
listenfd heard something, setting up new client
Accepted 192.168.0.1:3313 as client[3]
>From 192.168.0.1:3313, Client[3]: Hello
----------------------------------------------------------------------------
----
Warning: socket_read() unable to read from socket [0]: An established
connection was aborted by the software in your host machine. in
D:\test\socket\server.php on line 150
Closing client[3] (192.168.0.1:3313)
Question
========
What caused the warning message and how to I fix it?
PS

If possible, please help me to improve these code, thanks.

Hi
All,
Can someone elaborate on How to Select multiples tables of different
database in one query, perticularly when using php as scripting
language.
Regards
TM
|
--- End Message ---
--- Begin Message ---
Not difficult :
database db1
database db2
database db3
select db1.table3.column2, db2.table5.column1, db3.table1.column7 FROM
db1.table3, db2.table5, db3.table1;
You can use alias in FROM on table like this :
select alias1.column2, alias2.column1, alias3.column7 FROM db1.table3 AS
alias1, db2.table5 AS alias2, db3.table1 AS alias3;
Warning : the mysql user MUST have select (or insert, update, delete)
right access on db1, db2 and db3.

Warning 2 : it is a mysql example. Whith other DBM, i don't know how to
do that, but i think that its exactly the same thing.
PHP version : mysql_query($query).
