With what error message? Have you tried logging in with SSH or similar
and trying the same command?

More than likely the user apache is running as doesn't have permissions
to chown -- in fact I believe that in order to chown files one must be
root (at least that's the way it seems to work on my system).

You could use chmod instead to allow the "admin" user access to your files.

Hi Jasper,

When using my Php script, I don't see any error messages.

I have logged in using SSH, but the directories created are
owned by 48 and not my ftp user and so I have to switch
to a super user to make any changes.

Also, even though I use:
mkdir("$endpath", 0777);
The resulting directories end up as 755.

Yeah I have a feeling that you are right, that apache on
my server does not have chown permissions.

Thank you very mych for your help.

Keith

We use a combination of locking the record using a simple boolean column
together with the user id who has locked the item and the timestamp.

The locking prevents another user from opening the form and happily
editing away without realising his changes will be lost when he presses
submit. The user id is to inform the second user who has opened the
document, and the timestemp is so that the first guy doesnt open the
document and go out for lunch leaving it locked. We default it to 5
minutes after which someone else can open the document and edit it.

I think I'm going to go with Jasper's suggestion, re: simply
timestamping the current edit from the preceding version and testing
that timestamp against the existence of more recent edits and throwing
back to the user a request to resolve their changes against the now
'current' version.

I had been thinking about a timed locking strategy (5 minutes seems
short, though, for content creation, and what do you currently do when
person A comes back from lunch, person B has made an edit in the same
entry after person A's lock timed out, and person A commits their now
aged edit? Do you basically throw an error anyway, and ask person A to
resolve?), and perhaps implementing a simple javascript countdown on the
page to alert the person editing the page when time for their edit is
running out, but in all honesty I think throwing back the error, and
perhaps presenting a diff of the newer version of the entry, and the
version the user has edited, might be the way to go.

Either way, gives me plenty to think about.

Out of curiosity, does anyone know if it's possible to tell whether an
individual session is still alive from PHP? I don't mean from within
code being run for a particular user, but in code that, for example,
might be executed by a cron job, which would examine a table in which
session ids have been recorded automatically for each visitor, and
determining which of those sessions are still theoretically alive? I
suspect this isn't possible, but I've also learned to never
underestimate the ingenuity of those faced with things that aren't possible.

Much warmth,

Check out the user contributed notes on the manual page - www.php.net/ldap

A few of them refer to Active Directory.

If you installed PHP from source, then you need to install OpenLDAP or
some other ldap package to get the client libraries.

If you installed PHP from packages, then you need to install the
php-ldap package(assuming the functions do not currently work)

If someone else installed PHP, then you need to get them to install
the LDAP extensions to PHP.

Some characters are encoded. I've never used domit but I have used php5's DOM.
http://us2.php.net/manual/en/ref.dom.php

To get them back to the characters simple run it through
htmlspecialchars_decode
http://us2.php.net/manual/en/function.htmlspecialchars-decode.php

If your still using PHP4 use this instead.
function htmlspecialchars_decode_PHP4($uSTR)
{
 return strtr($uSTR, array_flip(get_html_translation_table(HTML_ENTITIES,
ENT_QUOTES)));
}

I've not personally tested it but it's found on that page.

Erik,

The easiest way to make sure that all characters are represented
correctly is to specify the UTF-8 codepage on your HTML pages and making
sure that you edit and save your XML documents with an editor that is
capable of handling UTF-8, such as Windows Notepad (W2000 or later I
think) or Editplus from editplus.com, or one of the major editors, such
as Dreamweaver or Visual Studio or Zend Studio.

This ought to fix most problems.

Torgny

How can I disable auto-commit for a Postgres connection? Apparently
server-side autocommit was thrown out in Postgres 8.0, and clients have to
issue their own setting (which is sensible).

The default is on (which I don't want). psql is apparently able to set or
unset the AUTOCOMMIT option, but I found nothing similar for PHP.

There is no ini setting for it. There is no function for it. Perhaps the
"options" part of the connection string passed to pg_connect() might work, if
I only knew what it's supposed to contain... Can anybody shed some light on
this?

Apparently this will work (or at least it will be accepted by pg_connect):

$conn = pg_connect("dbname=test host=localhost user=postgres options='-c
AUTOCOMMIT=true'");

Warning: it fails if you use values other than those that will set it to true
(true, on, 1). Apparently you can't use false, off, 0. But I've noticed you
can leave the value empty:

$conn = pg_connect("dbname=test host=localhost user=postgres options='-c
AUTOCOMMIT='");

Hopefully, this has the "off" effect. Will have to test more.

Hello,
I've been installing php-4.4.0 and php-5.0.5, and it both cases I can't find
the "pear" executable in the install directory. For instance:
# ls /usr/local/php-5.0.5/bin/
php php-config phpize

IIRC, pear executable (ie. the package manager) used to be bundled with PHP.
In fact, I think a while a go I compiled from the daily snapshot and I got
the pear executable. My configure options have not changed since then (look
below). Any help ?

Hello,
What I meant by the "pear executable" is actually a shell based (which
then run php) script that acts as the pear "frontend / package manager".
Thanks for the link and summary on how to install that manually, but I
was just curious why it wasn't built automatically when I 'make install'
php, since as I mentioned, IIRC previous version of PHP gives you this.

Thanks.

I believe you're right, they used to include it with PHP. I believe the PEAR docs even say something about it being included. Maybe they don't anymore so you have to go to the PEAR site to get the latest installer. That way they don't get people using an older installer/package manager that may not be the latest update. *shrug*

Either way, the info I sent earlier should get you up and running in no time.

Good luck!

I use "gmane.comp.php.general" to access the lists. They require a valid

created.

we obviously don't have the budget for that. Any thoughts/suggestions
would be very much appreciated. Thanks.
