There was some problem related to libxml2. I even tried down loading the 
libxml2 rpm and upgraded the package.Even then some other problem occured 
related to libxml2.

You didn't specify but I guess all your databases are on the same server.

When accessing multiple databases on the same server using multiple
instances of a class, you need to make multiple connections to the server.

By default PHP creates only ONE connection to a server and the database you
select is linked to the connection. So instantiating another instance will
use the previous established connection and change the database.

To force a new connection, you need to use mysql_connect() instead of
mysql_pconnect(). When using mysql_connect() you can specify:

$this->dbh = @mysql_connect($db_host, $db_user, $db_pass, true);

[quote from="PHP manual"]
resource mysql_connect ( [string server [, string username [, string
password [, bool new_link [, int client_flags ] )
[/quote]

Which will force a new connection. By default PHP will use a connection
which have already been established.

Take care when doing this as each time you instantiate a class a new
connection to the database will be created adding additional load on your
database which can cause a denial of service.

I normally store a list of connections to servers and databases in a
variable which can be accessed by the script. Every time I instantiate a new
instance of my database class I first make sure that a connection to that
server and database does not already exist. If it does exist then I call
mysql_connect() without the true for new_link otherwise I call
mysql_connect() with the true for new_link.

The downside of this is that you do not have persistent connections which
last beyond the end of the script.

Hope it helps

Albert

[PHP] Database Class Help

2005-11-30 Thread Ian Barnes
Hi,

We have a database class that we want to use to connect to multiple
databases at the same time using different variables.

Here is part of the db class:

class db {
  var $dbh = "";
  var $q   = "";

  function db($db_host, $db_user, $db_pass, $db_name) {
$this->dbh = @mysql_pconnect($db_host, $db_user, $db_pass);
$this->select_db($db_name);
  }

  function select_db($db) {
if ([EMAIL PROTECTED]($db, $this->dbh)) {
  die("Cannot select database because:\n" .
mysql_error() . "");
}
  }

  function num_rows($_q) {
if (!$this->q = mysql_query($_q, $this->dbh)) {
  die("Invalid query \"" . $_q . "\"\n" .
mysql_error() . "");
} else {
  return mysql_num_rows($this->q);
}
@mysql_free_result($this->q);
  }
}

In my php file I say something like

num_rows('select * from table1');
Echo $db_2->num_rows('select * from table2');

?>


Now that happens is when I try and do the query for db1, I get told that
db2.table1 doesn't exist. I can swop anything around and it doesn't seem to
work for one of the classes.

Does anyone have any idea as to why this is happening?

Thanks a lot,
Ian

Except this passes the "message" in the URL.  Is there a way to pass 
variables as a POST (not in the URL)?


I have a class that creates a new socket, however on my client's shared

able to pass the variable information via the socket (POST).

Ladies and Gentlemen,

Thankyou for this opportunity of picking someones brains before I tear the 
place apart.  I am just starting with PHP but have encountered an 
insurmountable hurdle..  I need to work through   HTML form  "posting" 
examples to a PHP script.  ONE STEP after "Hello World"


I have taken the following steps:

1:   My php.ini   (The only one on the system ) is located in /etc/php.ini

Because I am using an above 4.1 version of PHP
I have manually altered the values of

register_globals = On

2: I have repeatedly stopped and restarted Apache webserver.
(Version 2)

3.  I have a "Hello World" HTML - > hello.php  that loads and runs 
succesfully hence I have a valid   Webserver PHP HTML connection with my 
browser.


4. In "Hello World I have taken the liberty of including a  phpinfo()

5. The output of phpinfo()  among others reveals:

post_max_size 8M 8M
precision 14 14
register_argc_argv On On
register_globals On On
safe_mode Off Off

5. I should   be able to use GLOBALS  ( even if this will become a

You could also replace:

if (!preg_match('/([0-9]*)(\\.0*)?/', $_POST['x'])

with:


if(!is_numeric($_POST['x']) || $_POST['x'] < 0)

This would ensure that your value only contains numbers, and that it is 
greater than zero.  Then when you put it into the $_CLEAN array, you can 
type-cast it as an int (as in the other script) and that would convert 
any doubles to an integer value.  If you wanted you could also round, 
ceil, or floor the value.

Let me see if I got this right.

You have Dir x, y, z, w.  In each dir you have files 1 through n.

What you want to do is loop through each dir and then loop through
each drawing and look for some pattern in the title block and then
append the query info there.

If this is the case: you should use chdir() to change dirs.  Then you
can readdir() and loop through the files.

Does this help?

Theoretically you should be able to use a javascript function in the
page unload to submit back to your server when somebody navigates away
from your page. Not sure if it would work 100% of the time but its
worth a try.

PHP4 works just fine with MySQL 4.1. You may be encountering a  
"problem" with the new password scheme in MySQL 4.1 that PHP 4 does  
not support. In this case, PHP4 is considered and "old" client. Read  
this part of the manual to get it working:

http://dev.mysql.com/doc/refman/5.0/en/old-client.html

Should you upgrade to PHP5 is a completely different story. There are

[PHP] custom CAD directory/file browser

2005-11-30 Thread Marlin Unruh
I have hundreds of CAD drawing files in binary format. Using the 
strpos() function I can query embedded ASCII info from the CAD files. I 
display the queried info along with an anchor element to the CAD file in 
the web browser using a php script. Thus I can give the drawings 
arbitrary file names but find the file I am looking for from the 
description in the drawings title block.  I can handle that aspect of 
the project all right, the question is how to handle the directories. If 
I create an anchor to the directories it drops out of the script and use 
the browsers file viewing functionality. I think what I need is for the 
php script to call itself and pass the name of the new directory so the 
new directory can be queried and displayed.


Can I use an anchor element to pass info back to the self same php 
script? If so how? I can't seem to find my way though this aspect of the 
project.


Point me to a tutorial, give me a clue, or let me struggle on.

Thanks

Disregarding your question about databases: Yes you should. PHP5 is
there since well over a year. The dev team WILL stop support for PHP4,
be it sooner or later. With the 5.1 release there are no speed arguments
for PHP4 anymore. If you switch now, you are avoiding bigger adjustment
problems in the future.

Tip: Look at the relase notes of the different XAMPP versions. They
always bundle a PHP4 version with a MySQL version and they have changed
to MySQL 4.1 very early. Any download they offer means that the
contained versions work well together.

[PHP] Re: page duration tracking

2005-11-30 Thread Ben

MikeL said the following on 11/30/2005 11:39 AM:

Is there a way to incorporate some type of time in a page to track the
duration of time each individual visitor spent on a specific page with ..PHP?
 
I know I can keep a counter with JavaScript, but I would like it to keep

track in my stats file.
 
I can track & log the arrival time, but would like to either track the page

exit time, too.  It would be great to convert it to minutes:seconds for time
spent viewing the page.
 
I only want to track how much time someone spends on my index.php page

before they leave the page.  I can track when they click to the next page in
my site.


You can only track the amount of time between page/file loads within 
your own site.  Record the time when a page loads and then when the 
person loads another page on your site you can compare the times to 
figure out how long they were on the previous page.


There is no reliable way to record if they leave your stie for another 
site or close their browser.

I mean if I knew all active session id's I could compare them to the

INSERT INTO members_online

// Get active session ids from table:
php code

// Compare active session ids with table sessions:

I already use a class to perform this task. The problem is if a member
closes the browser windows and then tries to login again before the
specified timeout.

Does Apache have a function like asp Session_OnStart, Session_OnEnd ?

I am using IIS and PHP 5.0.4

[PHP] include_once behaves differently in mod_php4 vs php5-cgi

2005-11-30 Thread Toomas Aas

Hello!

There's a website with a following structure

index.php in the site's DocumentRoot directory (for this thread, let's 
call it /www)


functions.php, init.php and db_connect.php in /www/library

index.php includes line:

include_once('library/functions.php');

functions.php includes lines:

include_once('db_connect.php');
include_once('init.php');

The website was running fine under PHP 4.4.0 installed as Apache module.

Then we tried it with PHP 5.0.5 installed as CGI. We got the following 
errors:


PHP Warning:  main() : open_basedir restriction in effect. 
File(/db_connect.php) is not within the allowed path(s): 
(/www:/usr/local/www/phpMyAdmin:/var/tmp/php) in 
/www/library/functions.php on line 2
PHP Warning:  main(db_connect.php) : failed to open stream: Operation 
not permitted in /www/library/functions.php on line 2
PHP Warning:  main() : Failed opening 'db_connect.php' for inclusion 
(include_path='.:') in /www/library/functions.php on line 2


...and similar 3 messages about init.php.

Note that first warning is about '/db_connect.php', not 'db_connect.php' 
or './db_connect.php'. /www/library should be inside the open_basedir, 
since it is under /www, which is listed in open_basedir in php.ini. It 
looks like something is changed in PHP's behaviour between versions 4 
and 5 or is differently handled in CGI vs Apache SAPI, but I find it 
unlikely since I can find no documentation regarding this. It's more 
likely that I am overlooking something trivial, but I can't figure out 
what it is.


I tried to change the include lines to

include_once('./db_connect.php');
include_once('./init.php');

but this made no difference.

However, when I specify the full path:

include_once('/www/library/db_connect.php');
include_once('/www/library/init.php');

then the errors disappear and 'everything' seems to work.

Also, I never get any errors about the

include_once('library/funcions.php');

line in index.php

I'm puzzled...

Which reminds me... make sure your using include() where appropriate,
and include_once() where appropriate. Obviously include_once() should
ALWAYS be used when the source contains function or class definitions.

Re: [PHP] php related segmentation fault with Apache 2.0.55

2005-11-30 Thread kristina clair
Hi again,

I tried compiling and installing php 4.4.1 with Apache 2.0.54, out of
curiosity (because php 4.3.10 and Apache 2.0.54 didn't give me any
problems).

With this combination, I still get a segmentation fault with at least
one php script.  The gdb backtrace is:
#0  0xb7e207c1 in php_handler (r=0xda16ca8)
at /home/sys/src/php-4.4.1/sapi/apache2handler/sapi_apache2.c:538

PHP_MAGIC_TYPE) && strcmp(parent_req->handler, PHP_SOURCE_MAGIC_TYPE)
&& strcmp(parent_req->handler, PHP_SCRIPT)) {
(gdb) bt full

__mask_was_saved = 0, __saved_mask = {__val = {
0 
ctx = (php_struct *) 0xda08818
conf = Variable "conf" is not available.

I think it is worth reiterating that this is only happening with one
script, to our knowledge.  The actual file being served is a .shtml
file which includes a php script.  I looked at the php script, and it
looks like a pretty straightforward database access script, using
mysql.  Is there anything I should look for in that script?

Thanks,
Kristina

Re: [PHP] Schroedinger's Bug - may require exorcism...

2005-11-30 Thread tg-php
What to do next?  I'd check to see if your page is being inadvertantly called 
twice (I've seen this happen when people used frames.. or like someone else 
mentioned, doing a double include() or sometimes redirecting back to itself via 
header())... anything that could possibly re-initiate the page, check into.

Failing that, do it old school...  just inserted die() statements to break 
execution at various points and see where the probably first starts occuring 
and focus in that area.  Crude but it works.  At least helps narrow down where 
the problem could be.

It doesn't do something silly like include() itself inside a conditional 
somewhere does it?

You might also echo/var_dump/print_r/whatever some of your key variables 
(especially input variables like $_GET/$_POST/etc and variables used in 
conditionals) and try to isolate what combination causes your problem.  Since 
it doesn't do it all the time, I'd guess you could have something like:

$x = 4;

if ($x > 1) {
  include('someinclude.inc');
}

if ($x < 5) {
  include('someinclude.inc');
}

Where 'someinclude.inc' contains your double declarations.


Next point... check your logic around your include()/require()s and such.  
Maybe you have a condition where something is falling into multiple categories.


The logic puzzle is as much about writing good logic as untangling possibly 
flawed logic.

If all else fails, trace through your code by hand... interpret it in your head 
like the computer would.. like by line.. maybe you'll see where something is 
ambiguous and under certain conditions creates a fail.

Let us know what you find.. kind of curious myself.

-TG

= = = Original message = = =

So... I have this script (being called in a perfectly typical way by  
PHP 4.4.1 through mod_php in Apache 2.0.55) which sometimes runs  
perfectly, and sometimes chooses, totally haphazardly, to seemingly  
run itself twice, which of course causes it to die with a fatal error  
after it tries to redefine some functions.

As mysterious as that is, it turns out it must be something  
altogether more sinister. I tried putting die() at the end of the  
script, on the assumption that it was for some reason executing  
twice, yet behold: the problem is still present, and the PHP error  
log still complains about constants and functions being redefined!  
The problem, I therefore thought, cannot be that the script is being  
run twice. (In retrospect, this was the most likely possibility,  
because the page doesn't actually output anything if it dies with  
this error.) So for debugging, I added a bit that logs one message to  
a file immediately before the die() at the end of the file, and a  
different message after the die(). The die() seems to be working  
normally, in that it only logs the first message...

But wait a second! WTF? If the PHP error log is to be believed, then  
the script should be dying with a fatal error before it even *gets*  
to that point in the script, isn't it?

And the greater WTF is the fact that, as I mentioned above, every  
time the page is requested, it unpredictably either does this or  
works flawlessly. Oh my. How do I even *begin* to debug something  
like this?

Thanks for any help.

[PHP] Lowest PHP version to work with MySQL 4.1.x

2005-11-30 Thread AmirBehzad Eslami
Hi List,

I have noted that some versions of PHP are unable to work with MySQL 4.1.x.

1) Should I upgrade to PHP 5?
2) What is the lowest PHP version which works fine with MySQL 4.1.x?

Regards,
Behzad

P.S.
I don't use "Improved MySQL" extension in PHP.
I just need MySQL 4.1.x for multi-byte character support.

It sounds like you have a PHP script with a security vulnerability, and 
you think that restricting what the client uses to request the script is 
going to fix it. This is not a good approach. Just fix the problem. :-)


For example, filter the data you receive from the client before passing 
it as arguments to the mail() function.


Hope that helps.

no. the webserver only sees the incoming request - given that what

possibly tell who/what sent the request (other than trusting the client that
its telling the truth)?

granted there may be ways (hackish or not) to make some kind of determination

"if you have to ask  "

If you're willing to ditch the "windows mobile" requirement (Wince/WM is 
crap anyway) then you could have a look at the Sharp Zaurus series. Run 
www.pocketworkstation.org on one of the Zaurus and you'll have access to 
most of Debian in the palm of your hand. I've successfully run FUDforum 
using Apache2/PHP4/MySQL on my Zaurus. Ruby on Rails works as well albeit 
a tad slow -- I need to figure out how to get fastcgi working. And unlike 
WM devices, you can run *real* browsers, Firefox and Mozilla are 
available.

[PHP] XSS via curl

2005-11-30 Thread Sandy Keathley
My company uses a home-grown formmail script for clients 
, and someone is using curl to inject HTTP headers and 
spam email addresses, and turn it into an open relay. Yes, I know 
the right answer is to not use a formmail, but I don't make the rules 
here.

Is there a way to detect that a script is being accessed by curl, and 
not by a browser?  ENV ($_SERVER) variables won't work, as 
those can be forged.

Thanks.

[PHP] PHP on Mobile Devices(Pocket PC specifically)

2005-11-30 Thread Kilbride, James
Does anybody know of a way to run PHP files on a windows mobile
device(Pocket PC 2003)? Optimally I'd like to run it under a web server
running on the mobile device itself but barring that I'll take some form
of command line I guess. Realize that the mobile device will NOT be
running any active network connectivity. For all intents and purposes
the individual is sitting in a wireless empty room with no land
connectivity talking to the mobile device. I haven't been able to find
any web servers that run on the Pocket PC that can be viewed by the
mobile IE(or mobile Opera either I guess) when it doesn't have active
connectivity, at which point I might as well just be using a server for
all of the mobile devices rather than hiding it on the mobile device.

Re: [PHP] checkboxes

2005-11-30 Thread Brent Baisley
Excellent response. You should always be expecting certain data. So  
if no checkboxes are checked, your code should realize that since it  
was expecting the data and none was submitted.
The "lazy way" is much easier to code, but it is actually fairly  
efficient. You are only hitting the database twice, once of the  
delete and once for the bulk insert. On a fixed record length table,  
the lazy way may actually be quicker.

Decide as we go approach and clean up:

  1) Grap the 'vehicles' currently assoicated with the 'lot'
  2) if 'vehicle' is currently selected do nothing
  3) if 'vehicle' is a new item we should add 'vehicle' as long as it
 is a valid 'vehicle;
  4) repeat 2 and 3 until we looked at all the data
  5) figure out which ones should be deleted and delete them.


Forget everything, we'll add what is valid (the lazy way):

  1) delete every associated record to the 'lot'
  2) for each 'vehicle' add 'vehicle' as long as it is a valid
 'vehicle'

Here is what I have done using MySQL:

-> `name` char(20) default '0',
-> PRIMARY KEY  (`id`)

Query OK, 1 row affected (0.00 sec)

mysql> INSERT INTO tablename (id, name) VALUES (NULL, '\'Piet');
Query OK, 1 row affected (0.00 sec)

mysql> INSERT INTO tablename (id, name) VALUES (NULL, '\'Koos');
Query OK, 1 row affected (0.00 sec)

mysql> INSERT INTO tablename (id, name) VALUES (NULL, 'Jan');
Query OK, 1 row affected (0.00 sec)

mysql> INSERT INTO tablename (id, name) VALUES (NULL, 'Gert');
Query OK, 1 row affected (0.00 sec)

** Then retrieve all the record starting with an apostrophe ('):
mysql> SELECT * FROM tablename WHERE name LIKE '\'%';
++-+
| id | name|
++-+
|  1 | 'Albert |
|  2 | 'Piet   |

excuse me but:

1. the OP asked for the size of the file, not the number of bytes it takes
up on disk (which are eaten up in fixed increments aka clusters) - then again
chances are the OP didn't consider that there may be a difference, so he'll have
to figure out which of the 2 number is actually important to him.

2. you don't seem to know what 'efficient' means, generating a wrong (in your
opinion) size consitutes wrongness not inefficiency. I called it inefficient
because it requires that the whole file is read into php's memoryspace.

something like (although its not very efficient, I think):

$data = ob_get_contents();
ob_end_clean;

$byteCount = strlen($data);

You could write the session id into a table when the session is started,
along with the start time.
Something like

sessionid CHAR|starttime DATETIME|lastvisittime DATETIME

You could then update this table each time the user visits a page, and
delete it if the interval between starttime and lastvisittime is longer than
you want. A cron job/scheduled task could be used to clean this table up
periodically


a nice description of 'session garbage collection' :-) 
which is pretty much all you can do in terms of 'logoff'.
