Could it be the other way around, i.e. Windows is stripping slashes, and
Linux is not? How does $contents come to exist in the script?
Check for any difference in your ini files for magic_quotes_runtime.

Hi
My ISP upgraded from 5.0.3 to 5.1.1. Since then, XSLT (at least my
script which uses it) doesn't work anymore.
The first error message on
http://www.pinkjuice.com/hayashi/materials/
is
Warning: XSLTProcessor::importStylesheet()
[function.importStylesheet]: Undefined variable in
/[...]/hayashi/pages.php5 on line 12
pages.php5:
<?php
# print dirname(__FILE__);
$xslt = new DomDocument();
$xslt->load("this.xslt");
$inputdom = new DomDocument();
$inputdom->load("../page_template.xml");
$proc = new XsltProcessor();
# previous version of the following line:
# $xslt = $proc->importStylesheet($xslt);
$proc->importStylesheet($xslt);
$proc->setParameter(null, "pagedir", $pagedir);
# seems to set params *and* toplevel variables
# $proc->setParameter(null, "topdir", $topdir);
$newdom = $proc->transformToDoc($inputdom);
print $newdom->saveXML();

Thanks in advance,

First of all, check the PostgreSQL docs on loading data - there may be a
native method you can call. Otherwise you normally export Excel to a .csv
file and import that.
How?
Never done it, but how about a combination of fgetcsv() and pg_copy() or
pg_insert()? There may be a tool out there on the web, have you googled for
"postgresql import excel"?

Hi,
I have a form on my site with many file fields for users to upload files. I
am trying to verify that for each file uploaded it corresponds with the name
of the file field i.e.
<tr>
<td>File_1.CSV:</td>
<td><input type="file" name="File_1.CSV"></td>
</tr>
<tr>
<td>File_2.CSV:</td>
<td><input type="file" name="File_2.CSV"></td>
</tr>
However if I loop through the $_FILES array like this:
foreach( $_FILES as $key => $value ){
echo '$key = '.$key.'<br />';
echo '$value = '.$value.'<br />';
}
$key = File_1_CSV
$value['name'] = File_1.CSV
$key = File_2_CSV
$value['name'] = File_2.CSV
The . is replaced with an underscore in the $key value. I could get around
this with a substr() but it seems a little inelegant, can anyone tell me why
this is happening please?
Thanks for your advice.

Shaun,
That is the documented behaviour for form fields in PHP.
See "Dots in incoming variable names" on the following page:

Periods are not allowed in variable names and are replaced by an underscore.
You could use regex to do the replacement so that you can do comparison.

However....
For loops:
$new_array= array();
foreach($old array as $value){
$new_array= $value:
}
Otherwise, all you'll get it the last assignment of $new_array as a variable,
not an array.
You can also use;
foreach($old array as $value){
$new_array[]= $value:
}
But sometimes, if the expression is a bit fancy in the loop and you are using
$keys, it is easy to make a mistake.

which is exactly what you get if yuou run the code above - after

regardless of whether you init the var you still have to

1. using the word 'Taint' there makes no sense.
2. secondly your example code didn't even parse.
3. I don't need to bloody try it, but just for you I did - so now you
can explain the following ouput (i.e. that after the loop has run $new_array
is equal to the string 'A'):

What I said was that arrays can be handled two different ways for loops.
1] By assigning the variable prior to the loop [i.e., $new_array= array();]
2] Or, by using inside the loop: $new_array[]= $value
Either one works. I've found, when the loop has lots of fancy stuff involving the $new_array, it is useful to go ahead
a assign it before starting the loop.

imho
I agree always declare all kinds of variables before using
in the specific situation you have to consider that you are using two
different variables
rthe $foo inside the function and the $foo outside the function I think
its' correct to declar both, imho you should use different names
if you want to check all variables are properly declared you can turn on
error reporting for all during development and wwitch it off again in
production

In the examples I saw, when you used $new_array = $value (without the []), you
weren't going to get a proper copy of the array, as multiple people stated.
I'm curious why I didn't see (or maybe I just missed it) something like this:
$old_array = array('one', 'two', 'three', 'four');
$new_array = $old_array;
?
If you use a foreach() loop, you definitely need to use []:
foreach ($old_array as $value) {
$new_array[] = $value;
}
You'll loose all your key associations unless you do:
foreach ($old_array as $key => $value) {
$new_array[$key] = $value;
}
If you want to destroy your keys, you can use the first example of a foreach()
or you can also use:
$new_array = array_values($old_array);
I'm lazy so I don't tend to pre-define variable types although I should
probably get into the practice when there's a security need to do so.
So what was the original question again? hah

What I said was that arrays can be handled two different ways for loops.
1] By assigning the variable prior to the loop [i.e., $new_array= array();]
2] Or, by using inside the loop: $new_array[]= $value
Either one works. I've found, when the loop has lots of fancy stuff involving
the $new_array, it is useful to go ahead
a assign it before starting the loop.

I'm writing a content management application which saves file paths in
a database and allows users to search the database for those files.
Problem I'm having is that although the PHP script that handles the
database queries works fine, when the search results get to the
browser, all the paths are off limits.
I can't just move the photos inside the web folder as we're talking
tens of thousands of images that are already organized into a folder
structure that must be maintained as is.
Is there a way to allow the web page to see these photos?
The images are stored on a Windows box and all the web server stuff is
on a G5 Macintosh running OS 10.4 3 (in case that has any bearing on
the matter).
Depending on security issues you have two options.
Put a webserver on the Windows box and modify your search results to
link to the images using something like this:
<img src="http://windowsbox/getimage.php?path=/path/to/img.jpg";>
Then put a "getimage.php" script on the windows box that does something
like:
<?php
readfile($_GET[path]);
?>
I would just like to add that you _must_ sanitize $_GET['path'], otherwise
stuff you don't want will get read.... like a passwd file or the secret
collection
of pr0n you have been hosting on the server at work ;-)
http://windowsbox/getimage.php?path=/etc/passwd";>
If you can't (or don't want to) put the windows box on the internet,
then still do the above and then also do the same on the mac. Assuming
the mac can get to the windows box. If that mac can't, then you're hosed.
good luck

Hello there,
Goal: Preventing multiple user login using the same username & password
from different location (
Simoltanous Login)
Options Available:
1) IP Checking: One way to prevent multiple people from using the same
account to gain access to a
restricted area of a site is to store their IP address in a database
table, along with the "time()"
they first logged in. You would then have to check the users IP address
on subsequent pages against the
value stored in the database to make sure that the user is still using
the same IP to view the page. If
the user has a different IP, we would prevent the user from login in and
display a message saying "You
are Currently Logged In from Another Location! Please Log from the other
location and try again" (or
something like that). This check is usually done at given time intervals
(say every 5 minutes or so)
Problem with Method: Several Internet Service Providers like AOL, change
the users IP Address every few
minutes. So this could potentially lock your REAL user out of the system
as well. There are also some
problems with Proxy Based connections.
2) Session ID Tracking: A similar idea to method 1, except that you
would store the SESSION ID in the
database, and instead of checking the IP, you would then compare the
users SESSION ID to verify that
the user is still the same user. The advantage of thsi method is that it
does not depend on the users
IP. Therefore AOL users will not have a problem with this login system.
Problem with Method: Although the SESSION ID is unique for current
active user, it can be assigned by
server to any other later on. Plus you may have problems with Session ID
based login system, if you use
a shared Webhost.
3) Boolean Login Field: With this method, you would basically create a
boolean field in your database,
and set the value to TRUE if the user is logged in, or false if the user
is not. Again, to check if the
user is still logged in, you would have to use a timestamp like previous
methods to see if the user has
been inactive for more then a specific period of time, and reset the
Boolean database field value to
false if the user is inactive (This could basically either mean that the
user just closed his web
browser and left, or that he took a longer then usual lunch break and
forgot about your site).
Or if the browser crashes valid user is left in the muddle.
Problem with Method: The basic problem with this method (as with the
other two methods), is that if you
set a time period (say 5 minutes) to give the visitor to go to the next
page and verify that he is
still alive and on your site, if the visitor takes longer then 5 minutes
to move on to the next page,
he will be locked out of the system for ANOTHER 5 minutes (until the
system clears the hold on his
account).
THE QUESTION:
Here is my main question about this whole issue. Is there a better way
of performing this task that
will not require the setting of a time interval to see if the user is
still logged in? IS THERE A GOOD SOLUTION TO THIS ISSUE???
Many Thanks in advance,

Where I work, the system that was set up before I got here uses session ID and
a timeout of a couple of hours. I'm pretty sure that there's a good chance
that two people would not be issued the same session ID within a short period
of time. Certainly not within say 4 hours.
Maybe someone has a better way, but I'd say this works out ok for us so far.

Hi all.
I've got a PHP script which does file uploads.
the files get uploaded fine but I see that the permission of the files are:
600
IE: Owner read and write.
In order for me to use the files, I would have to set the permissions on
each file, now for best practise would I set the permission once the
file is uploaded or is there something I can do before its uploaded?
usually when i have a file upload section all file permissions are fine,
this is the first time, so perhaps there is something with the current
permissions that is causing the permissions to be set to 600 when
uploaded, which if solved would allow me to not edit my PHP files.
any ideas?
thanks in advance

I have encountered a situation where I'm using the foreach() where I need to
assign new data to the $value in the foreach loop, foreach($x as $key ==>
$value). With PHP 5, you can do the ampersand to the $value but I'm using
PHP 4? So, how do you guys do it? I tried this sample code but it only work
in the child array but not the parent arrays... Food for Thought??
Thanks...
--code--
function XmlTreeCDataAsciiLoopThrough(&$tree)
{
foreach($tree as $key => $value)
{
if (is_array($value)) {
XmlTreeCDataAsciiLoopThrough($value);
} else {
if ($key == "VALUE") {
echo $tree[$key]." ###<br>";
$tree[$key] = "#############";
echo $tree[$key]." @@@<br>";
}
}
}
}

I'm working on a private webmail (and other) system, and am struggling a
little with MIME mails. I've got a script to save all the attachments, but
the thing I can't figure out is how I decide which "part" is the main email
message itself (and hence which to display).
Oh and cheers for the info someone gave me the other day, it inspired me to
just connect to the pop3 server using a raw socket, SOOOOO much easier!!!

Usually, the main part of the message, is the first non-attachment part
you find. So, if you have a tree like
mime1
|- text
|- mime2
|- attachment
|- another text (possibly mime3)
then the main part is text. Otherwise, just look for the first
text/plain or text/html mime-section you can find in the list (closest
to the top). If both a text/plain and a text/html section appear on the
same level, your script will need to decide which one to show (a lot of
mailers attach both a plain-text copy and an html copy of the text)

share the code please, I'm interested :)

Is there any way of converting an array to an object of a type/class
other than stdClass?
I have been using the new PDO system and have experimented with
fetching rows with PDO::FETCH_CLASS
I would quite like to do the same with a plain array.
Any comments appreciated.
