What happened to "make install" ???
You have to "make install" your new .so file to get copied over into your
PHP extensions directory, which from the messages seems to be
/usr/local/lib/php/extensions/no-debug-non-zts-20020429/ on your system...
I'm betting you have an 'ext/foo.so' file, but it's not installed yet.

No, there's none!
[EMAIL PROTECTED] ext]$ pwd
/home/deep/php-4.3.10/ext
[EMAIL PROTECTED] ext]$ find . -name "*.so"
[EMAIL PROTECTED] ext]$
I gave this find after saying './buildconf --force', './configure
--with-nscli', 'make'.
(Which is what the ext_skel script asked me to do, after editing
config.m4)
Thanks for all the help, I think I'm still not done, however.

Search the http://php.net/ site for "HTTP_RAW_POST_DATA"
I think that will have what you want.

I would avoid this route -- Mainly because to give PHP permission to copy
files onto Robert's computer will open up some pretty major security holes
in every single desktop machine.

This seems perfectly reasonable approach.
Once you have assigned a file to 'robert' in the database, then you can
let 'robert' download the file -- or even a zip file with all 200 files in
it.
The downloaded file will have the correct Windows extension -- or they
will after 'robert' unzips them, and Windows will open the right software,
if 'robert' has it installed and the machine is configured correctly.
If it's not installed or the machine isn't configured correctly, there is
nothing you can do about it from PHP.
Then 'robert' can work on them, and, when they are finished, they can
upload the edited files.
You can track when 'robert' downloaded the files, and when 'robert'
uploaded the files.
If you want to do it one file at a time you could track each and every
download/upload -- but it would be very painful for 'robert' to download
every single file and upload every single file.
Most likely, just knowing that 'robert' downloaded 200 files, took 43
minutes to work on them, and uploaded them again, is plenty of info to
track productivity.

Hi,
Now I want to see all my temporary php files in /tmp/php.
I made these settings:
[EMAIL PROTECTED]:~# cat /etc/php.ini |grep /tmp/php
upload_tmp_dir =/tmp/php
session.save_path = "/tmp/php"
soap.wsdl_cache_dir="/tmp/php"
[EMAIL PROTECTED]:~#
But when I use gzopen() or gzfile() the temporary files are still stored
in /tmp/
What other settings should I make?
You need to set enviroment variables $TMPDIR and $TMP. I'm not sure
which one of these are used by those functions, but you can safely
change both.

This is actually my first venture to PHP extensions. I am trying to
write a simple C function, which prints 'hello world', as a PHP
extension.
I defined a helloworld.proto as:
int helloworld() prints hello, world
executed ext_skel, and followed the remaining steps that it showed
on-screen, including editing config.m4.

I'm sorry my previous mail appeared twice - I was confused by a

When a session object is created - where is it store? (Perhaps on the
application server - IIS or Appatche?) Or on a cookking on a user's
computer?
To destroy the session object (widht all session vairables inside the
particluar session object) can I use session_destroy();
What is also the default life span of a session object? and can this
bechanged?

Well, if you look in your phpinfo() file, you will see a SESSION_TIMEOUT or
SESSION_LENGTH value that is something like 180000... different for each
server.
If you hold all your session values in the array, then you can use
session_destory(); as long as session_start() is previous to that.
I am under the impressions that both Sessions and Cookies are stored on the
user end, but I may be wrong.

Pedro,
Something has got to give somewhere. You can't have all those
requirements without some sort of trade off -- especially if you're
dealing with some sort of CMS or with content entered by some
non-technical writers. The common solution is to use PHP to write the
links for you in some way, using a globally available constant or
variable that holds a path prefix, and specifying all paths as absolute
URLs relative to that path.
<?php
$prefix = '/foo';
echo "<a href='{$prefix}/to/somewhere.html'>link</a>"
?>
The above example outputs <a href='/foo/to/somewhere.html'>link</a>
<?php
$prefix = '';
echo "<a href='{$prefix}/to/somewhere.html'>link</a>"
?>
But this just outputs <a href='/to/somewhere.html'>link</a>
In the context of HTML the link might look like this:
<a href="<?=$prefix?>/to/somewhere.html">link</a>
And if all that seems too awkward, you could write a helper function
which writes the links for you, eg:
<?
function link($text,$uri) {
global $prefix;
return "<a href='{$prefix}/{$uri}'>{$text}</a>";
}
$prefix = "/path";
?>
and then do this:
<?= link("click here","/to/something.html") ?>
Obviously the function could be extended to check for #fragments, but
without a doubt, the only safe way to write good URLs is to specify a
full path for everything except #fragments. Then if you need the
ability to move the site into directory, then specify a path prefix
which gets used when needed.
Passing the entire HTMl page through a URL parser/modifier would be
another option, but I'd be staying well clear of that.
I could go on for hours and provide plenty of reasons, and better
examples, but you need to do some of it yourself :) And if your answer
is "I only want to use plain HTML for the links, but still want to be
able to move my site into directories", then I'm afraid no one can
really help you, sorry.

Hi,
I wanted to gather opinions on what method is best for dealing with
relative URLs (i.e. in HTML links) on complex, multi-level directory
structures.
Here's what I have so far...
Goals:
1. Simpliest possible management of relative URLs.
2. Be able to move the entire site from one directory to another
without breaking links.
3. Be friendly with clean URL methods, such as using special query
strings like "server.com/index.php/products/item/10".
Methods:
Using static absolute URLs ("/absolute/path/") should of course be
considered obsolete as it doesn't comply with goal #2.
One possible method I tend to use is to transform all relative paths
into absolute with PHP before sending the document. This is a very
efficient but rather annoying method to work with, as most URLs need
to be pre-processed.
Another, generally cleaner method is to use the HTML base tag, which
allows one to define a base path for every relative URL found in the
document. This is however a nuisance whenever you need to link back to
the current document, such as with a regular relative query string
("?search=XX") or with a fragment link ("#section"), as the browser
would make them relative to the base path, forcing one to use the long
absolute URL each time.
Please tell me which you generally think is better and why, and if you
know any other method I could've missed.
Thanks,
Pedro Fayolle

Hi
I'm creating a webmail interface for a pop3-server (I know weird to do
webmail with pop3, but it's for a running server which I can't control.
So pop3 it is and caching the mails in a mysql database). I've
implemented the pop3-support myself since the one in www.php.net/imap
lacks a lot of basic pop3 features like uidl support.
Anyway I've hit a wall trying to add support for receiving attachments.
I'm not sure how to handle it. The imap_fetchstructure call doesn't seem
to be useful for me, since I can't send it text but only an imapstream.
I tried the pear projects mimeDecode class and it worked fine. But the
only thing it returns was the structure (like it will return an array
with info like one mime part plain text, one part image, etc.) and not
the content. I don't get the actual text and the actual image.
Any ideas of how I can get the content split up in neat pieces? I've
probably just missed something obvious in www.php.net/imap or the pear
mail classes. Because I guess there are a function that does this.
I need this running noooow. So I'm sort of desperate. If you have any
ideas at all please please speak.
Thanks.
Regards Emil
