Re: [PHP] Problem retrieving CN with ldap_search()
Hi all,
Sorry to reply to myself, but I finally solved the issue. In the end it
turned out it *did* have something to do with the LDAP configuration.
For some reason, retrieval of 'cn' attributes was disallowed, as can be
seen in this snippet from /etc/openldap/slapd.conf:
access to attrs=userPassword,userPKCS12,cn
by self write
by * auth
Removing 'cn' from 'attrs' solved the problem.
Best regards,
Marcel Loose.

Hi all,
I've posted this question to comp.lang.php a couple of days ago, but
up
till now didn't get a really useful answer. So, here it is:
I' m facing the following problem. I try to retrieve the Common Name
(cn) from an LDAP database, using the commands:
$result = ldap_search($ldap,$basedn, 'mail='.$email,
array('dn','cn'));
$entries = ldap_get_entries($ldap, $result);
The weird thing is that $entries[0]['cn'] is empty. I know the search
command succeeded, because $entries[0]['dn'] contains the correct
information. Furthermore, if I issue the following commands:
$result = ldap_search($ldap,$basedn, 'mail='.$email);
$entries = ldap_get_entries($ldap, $result);
var_dump($entries);
I get:
array(2) { [count]= int(1) [0]= array(24) { [objectclass]=
array(4) { [count]= int(3) [0]= string(13)
shadowAccount [1]= string(12) posixAccount [2]= string(13)
inetOrgPerson } [0]= string(11) objectclass [gecos]=
array(2) { [count]= int(1) [0]= string(12) Marcel Loose }
[1]= string(5) gecos [uid]= array(2) { [count]= int(1)

{ [count]= int(1) [0]= string(5) Loose } [3]= string(2)
sn [givenname]= array(2) { [count]= int(1) [0]= string(6)
Marcel } [4]= string(9) givenname [uidnumber]= array(2)
{ [count]= int(1) [0]= string(3) 511 } [5]= string(9)
uidnumber [mail]= array(2) { [count]= int(1) [0]=
string(15) lo...@astron.nl } [6]= string(4)
mail [gidnumber]= array(2) { [count]= int(1) [0]=
string(4) 1000 } [7]= string(9)
gidnumber [shadowlastchange]= array(2) { [count]= int(1)
[0]= string(5) 14127 } [8]= string(16)
shadowlastchange [homedirectory]= array(2) { [count]= int(1)
[0]= string(11) /home/loose } [9]= string(13)
homedirectory [loginshell]= array(2) { [count]= int(1)
[0]= string(9) /bin/bash } [10]= string(10)
loginshell [count]= int(11) [dn]= string(35)
uid=loose,ou=people,dc=astron,dc=nl } }
As can be seen, the Common Name (cn), is mysteriously missing. The
information IS present in the LDAP database, though. Here's a snippet
of the output of 'slapcat', for the given user:
dn: uid=loose,ou=people,dc=astron,dc=nl

Am I using ldap_search() incorrectly? Or is this a problem with the
PHP-LDAP module? Or is it a caused by a misconfiguration of LDAP?

Marcel Loose.

Re: [PHP] Dumb Question - Casting
According to the PHP manual using the same expression, Never cast an unknown fraction to integer, as this can sometimes lead to unexpected results. My guess is that since it is an expression of floating points, that the result is not quite 8 (for whatever reason). Therefore, it is rounded towards 0. Of course, that is only a guess, and I have no true documentation on it.

[PHP] Magnetic Stripe Reader or Barcode to PHP
I'll confess that I've done almost zero research on this topic as of right now aside from pricing readers and blank cards. So we're opening a new super-club here in Seattle. One of the ideas we'd like to pursue is that people are assigned a card. This can be a magstripe card or something with a barcode. Not really sure at the moment which way to go. The idea being that when they enter, we swipe/scan their card and we can log stats (# of visits, # guests, favorite drink so the bar has it ready, enter into contest, etc.) I was thinking we setup a simple netbook with a USB reader at the front door when they pay. Then we have another back at the bar. Connect via WiFi. Have a notebook somewhere behind the scenes that runs LAMP (or a VM thereof). No internet needed. The backend database and even web/GUI stuff is of course trivial with any LAMP stack. What I don't know is how do I interface _to_ PHP from say a magstripe reader. They're dirt cheap ($50), but I assume come with zero software. http://www.kanecal.net/mag-stripe-reader-scanner.html . And there are hundreds of these gadgets out there all the same basically. I guess what I'm hoping for is some pointers, from someone who's done this sort of thing. My gut thought is something so simple, where there is some XP software (or Linux I suppose) that reads the card (and generally they only have a number encoded on them) and this is sent via a URL we define, such as http://192.168.10.100/door.php?id=123456 or http://192.168.10.100/bar.php?id=123456 etc. (ignore the security issues and all that. It's trivial to encode the parameters, plus it's a closed system with WEP/WPA/WTF). But does anyone know of such a key piece of code? Like I said, I'm not locked into magcards. It could be a barcode reader just as easily. Or fingerprint scanner, or facial recognition. In the end it's just a unique thing that maps to a unique number.

Re: [PHP] Magnetic Stripe Reader or Barcode to PHP
If the scanning device hooks into the keyboard somehow it should be easy. I believe that's called a keyboard wedge. Basically, you scan and it types. My only exposure to this is using one of the old CueCat scanners to index my personal library into a php app I cobbled together. The CueCat hooked in line with the keyboard. You'd bring up the scanning page and an onload Javascript would place the cursor into the Scan ISBN Here text box. Scan the book and the input went where it was needed. I believe it also sent an enter keystroke which submitted the form. It's been a couple years since I played with it so there might have been some additional software that kicked the enter. Then you process the data as you would for any other text field submission. It worked well enough to catalog a couple thousand books in a single evening.

RE: [PHP] Magnetic Stripe Reader or Barcode to PHP
Bar code scanners can be setup to decode the scan code on the card and output it as text. On your incoming site, place cursor in text box, scan card, code on card is entered as text, hit enter, text field sent to database where all the F* Magic takes place. You will also need a method to create the cards and get the data into the database associated with the number. You can use Word or other text program and a bar code font to print the cards with bar-code, or use pre-printed peel and stick barcode labels to place on a card. To Initialize the card, have an new member interface where the data for the member is entered, along with their bar-coded number. There are a LARGE number of bar-code codes. Pick one of the more common that uses alphanumeric and symbols. Tips: Have a backup reader or hard wire the bar-code scanner into a power outlet. The cheaper hand held ones don't have a very good battery life. Print the number on the card under the bar code. This will help when a drink smears the bar code or it becomes unreadable. The door person can enter the number by hand.

Ave,
I'm trying to retrieve data from a DBF database and write it to a CSV

}
#WRITE TO CSV
@fwrite( $_fp, $_csv_data );
@fclose( $_fp );
I'm trying to adopt this piece of code for my use. I fixed the csv_data .=
trim error. Does anyone know how I can fix empty fields? Everything is
dumping to a csv file but information is not matching up. I don't know if I
can insert a space or something if field is blank?
What do you mean fix empty fields? And what do you mean by
information is not matching up?
You shouldn't insert spaces where there are blank fields. Just leave
them blank. The commas are supposed to delimit all the fields, including
the empty ones. Like:

DISCLAIMER - THOU ART ABOUT TO BEHOLD A RANT ... ok, so it all started out a few years back when i started a company set out to build a wireless capture portal. we wanted to integrate with a 2-Touch POS which had 'gift cards' which were magcards. the idea was someone buys a drink, the clerk swipes the card and the customer gets a window of time on the internet. so heres the deal (on linux [likely similar on other OS' though not sure on the implementation there]). when you attach a usb card reader, barcode scanner or similar, if you have linux USB HID (HumanInputDevice) support the kernel magically uses the module to treat input from the device as keyboard input; simple right... well this only works iff you have a terminal for the output to arrive at. if you dont it goes nowhere (likely /dev/null or similar). so if you want something quick and dirty, a laptop or any box w/ a full window manager or just a terminal will capture the output. but thats for newbs (haha)... the way we rolled w/ my product was w/ a linux server, running as the local gateway w/ a full lamp stack to provide a UI for the business owner and the customers. new problem - how to capture the output of the device w/o a terminal or UI on the server. to cut to the chase we ended up developing a *user space* driver for the card reader via libusb (which is cross-platform btw). i started out trying the java wrappers, but they all sucked ass.. so ended up going w/ C. basically, we wrote a simple single threaded daemon which sits and listens for card swipes, once the card is swiped, the daemon uses the C system() function to invoke a configurable executable program (which in our case was a php script :)) and passes the captured info from the card via the shell. the code is semi-generic but frankly we stopped off where our needs did at the time. the only real limitations are: . it only provides a fraction of the info from the card (all info could be passed ideally) . it has hardcoded values for a minimag card reader (easily changed - these are just values to identify the proper hardware in the USB tree and bind to it) . single threaded - it would be nice to have a main listener thread and fork child threads to process the swipes (thats where binary from the device is converted to ascii based on the usb2.0 spec) believe it or not you can actually send 2 swipes before the first one is processed w/ a single thread if you swipe it quickly enough! . dependent on glib for some string functionality - i think it would be nice to see it have as few dependencies beyond libusb (and pthreads if ever it was threaded), though glib is quite common afaik we originally ran the software on gentoo, but it could be packaged up for pretty much any OS afaik since libusb is cross-platform. anyways, if this is interesting at all im happy to share the code. i was
[PHP] array conversion
Hi guys. How to convert an array like: Array ( [0] = key1 [1] = value1 [2] = key2 [3] = value2 ) to Array ( [key1] = value1 [key2] = value2 ) Is there a built-in function to do this? Please Cc me. :) Thank you in advance. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I don't believe so, but rolling your own should not be too hard:
$a = array($key1, $value1, $key2, $value2);
$b = array();
$numitems = count($a);
for ($i = 0; $i $numitems; $i++) {
if ($i % 2 == 0) {
$saved_key = $a[$i];
}
elseif ($i % 2 == 1) {
$b[$saved_key] = $a[$i];
}
}
Code is crude and untested, but you get the idea.

This would be even shorter, I think:
foreach ($items as $i = $value) {
$temp[$i % 2][] = $value;
}
$done = array_combine($temp[0], $temp[1]);
(Also untested, just off the cuff...)

Re: [PHP] array conversion
Or,
function new_arr(array $arr)
{
$count = count($arr);
if ($count % 2 != 0) throw new Exception('The new_arr() function
requires an even number of elements.');
for ($i = 0; $i $count; $i += 2)
{
$new_arr[$arr[$i]] = $arr[$i + 1];
}
return $new_arr;
}
$test = new_arr(array('k1', 'v1', 'k2', 'v2', 'k3', 'v3'));
exit(var_dump($test));
