smbutil may or may not accept a password as an argument.
Something like:
smbutil --password=SECRET -v view //[EMAIL PROTECTED]
If not, you MIGHT be able to do:
system("echo SECRET\n | /usr/bin/smbutil -v view //[EMAIL PROTECTED]");
You may need to dink around with the \n part to get it into the shell
rather than in the PHP string...
system("echo -e \"SECRET\\n\" | /usr/bin/smbutil -v view //[EMAIL PROTECTED]");
You should use exec instead during experimentation at least, so you can
get error messages... Actually, exec is probably better all around,
unless you really need passthru for performance reasons...
smbutil *might* require a TTY (a REAL logged in person) the way some
programs do. If its documenation says so, I think you're out of luck on
the password bit.
There might be other options, like SSH key-pair authentication or
Kereberos or, for all I know, somebody wrote a PHP Samba Module while I
wasn't looking... I'd probably never use it, so wouldn't have noticed.

Thanks, Joe!
I see what you weer going after. I had several problems including the
fact that I really didn't understand what I was trying to do until after
I did it. And I had some log errors a friend helped with.
What I needed to do was delete the media types from the intersection
table and then insert them anew; that way I don't have to do all sorts
of looping through finding the status of checked and unchecked boxes etc.
Eventually I came to:
if (isset($_POST['editrecordMedia'])){
if (!empty($_POST['media_types'])) {
//TO make sure art_id isn't empty
if (!empty($art_id)) { //delete media_art entries for this art_id
$query="DELETE FROM media_art WHERE art_id='$art_id'";
mysql_query($query);
$query = "INSERT INTO `media_art`
(`media_id`,`art_id`) VALUES ";
$sep = "";
foreach($_POST['media_types'] as $type)
{
$query .= "$sep ('$type','$art_id')";
$sep = ", ";
Anyway, thanks so much for your help!!

if think you only need 2 '=' signs... i do this alot with arrays of
check boxes .. now don't quote me on this... but i do something like
this.. using arrays for the check box values
if($permissions_data <> NULL)
{
if(in_array($row_rsPermissions['permission_short_name'], $permissions_data))
{ $checked_per = " checked"; } else { $checked_per = ""; }
}
hope that helps you out

hi,
I'm severely frustrated and perhaps you can help with what I have done
wrong. The checkboxes I use to populate an intersection table work to
add the records, and now I am trying to update them. It's almost there
but producing some unexpected results when the form is submitted: the
idea is that it displays the checkboxes as pre-selected if they're
associated with the art_id in the intersection table. They're now
appearing as all unselected. Any help is appreciated.

Quoting "Murray @ PlanetThoughtful" <[EMAIL PROTECTED]>:
Hi All,
Just wondering if anyone knows of a free weather service that can be
interrogated by PHP for information such as current temperature for a range
of cities around the world?
Regards,
Murray
I *highly* recommend the PEAR Services_Weather package:
http://pear.php.net/package/Services_Weather
"Services_Weather searches for given locations and retrieves current
weather data and, dependent on the used service, also forecasts. Up to
now, GlobalWeather from CapeScience, Weather XML from EJSE (US only),
a XOAP service from Weather.com and METAR/TAF from NOAA are supported.
Further services will get included, if they become available, have a
usable API and are properly documented."
hth,
Rick

Yes, it would be nice if the list didn't relay this obvious cruft.
I'm s*bscribed to quite a few discussion lists, and php-general seems to be
the ONLY one relaying these malware messages and the claims of virus filters.
It looks rather like php-general is operating as an open list, seeing as
some of the addresses these messages are coming from clearly shouldn't
already be s*bscribed to the list, and the malware responsible for most of
it wouldn't actually perform a s*bscription.
At a minimum, I'd block the handful of known forgery addresses, plus block
postmaster@ and mailer-daemon@ messages from reaching the list. Yea,
bummer for the handful of people who use postmaster for their s*bscription
address (which is contrary to the purpose of the postmaster address, so no
loss there). I'd be quite happy if the list didn't accept attachments
either, but that would probably be a bit much to ask.
The appropriate solution would be to configure lists.php.net and any other
php.net mail hosts to use SMTP AUTH, and set them up with TLS certificates
and trusted relationships among one another using TLS (this is easy to do,
at least in sendmail - but php.net is running qmail...). After that is
done, set php.net hosts up to REJECT messages claiming to be from php.net
(proper AUTH or TLS will circumvent this rejection). End result: no more
forgeries through the php.net servers.

As with my previous post the problem is the pieces of the array can vary
from 1 to 4 items. So pieces 3 and 4 are often undefined giving the
'undefined index' notice. All I really want to do is display the array
pieces if they EXIST. But as they are inside a echo statement so I can't
even to a for loop...can I?
Any ideas?
R.
if ($quantity == 0){
}
else {
$pieces = explode(" ", $quantity);
$formatted_price = sprintf('%0.2f', $pricecode);
echo "<table width=\"240\" border=\"0\" cellpadding=\"2\"
cellspacing=\"5\"><tr><td valign=\"top\" align=\"right\"
width=\"40\">$pieces[0]</td><td align=\"left\" width=\"60\"></td><td
align=\"left\" width=\"200\">$pieces[1] $pieces[2] $pieces[3]
$pieces[4]</td><td valign=\"top\" align=\"left\"
width=\"80\">$formatted_price</td></tr></table>";
}
}

Not sure if it works for numeric indices, but maybe you could replace
$piece[3] with (array_key_exists(3, $piece) ? $piece[3] : ""). If you
want you could abstract that into a function, like
function array_access_element($key, $srch_array, $def=""){
return array_key_exists($key, $srch_array) ? $srch_array[$key] : $def;
}

Probably because $quantity IS 0, then the vars used in the else {} is
never set, but still in the script.
Try setting these before the if statement:
$pieces = array();
$formatted_price = 0;
$pricecode = 0; // this one is never set? Or set earlier in the script?

Close... I think array keys are preserved from the (original) first

After a var_dump I am seeing that there is an extra space in each
element of one array, so no intersection occurs.
Well then there you have it... having an extra space means that the
strings in the first array won't match the strings in the second array.
Perhaps you can array_intersect(array_walk($array1, 'trim'), $array2)
you'd want array_map not array_walk in this case:
array_intersect(array_map($array1, 'trim'), $array2)
also I found myself writing the following 2 funcs because the std

designate a group of files to be zipped up, including PDF files,
automagically. It must be compatible with WinZip as that is what the
user will have access to. I have tried several things, a couple of
classes, and some other tricks to no avail. There seems to be an issue
with PDF's that I cannot figure out. The files are usually 1 byte too
short when you try to open them after unzipping them, and are therefore
corrupt.
If anyone is aware of something would you please let me know? I am even
willing at this point to add a couple of layers of abstraction to make
this work as long as the process is relatively invisible to the end
user. My desire is that it works like this;
User clicks link
[start automagic stuff]
*whirring* //determine which files should go into archive
*clicking* //put files in archive
[/end automagic stuff]
User presented with dialog box to save archive
Any and all clues are appreciated.

hi...
i'm considering creating a short test app/game to allow users to use their
mouse to select items from a given image/pic. i'd like to be able to take
some basic shapes, and construct an image/mosaic from them. i'd then like to
be able to display the image to the user, and have the user select various
shapes in the image.
i'd also like to be able to determine what 'shape' the user is selecting
within the image via the mouse coordinates...
any ideas as to how this can be quickly developed/thrown together for
testing...
i kind of thought that this should be doable with php/imagemajick as an
apache app..
thanks

For the determining what part of the picture the user is refering to
I'd use image maps - which depending on your situation can be
serverside, or clientside.
I wouldn't bother with imagemagick, in this case, and just stick to gd.

Just so there is no confusion...I mistyped the line:
$names = substr(strrchr($_SERVER['QUERY_STRING'],"&"),7,1);
It should be a 5 instead of a 7 at the end:
$names = substr(strrchr($_SERVER['QUERY_STRING'],"&"),5,1);
