Re: [PHP] How do I POST data with headers & make the browser follow?

[Ragnar]

Hi Richard,

just to stop and everyone from getting a heart attack right this instant
what I am doing with cURL and the multiple pages attempt is not much
more scary than any other "person leaves credit card info on form" 
script you come across.

The server that I am re-sending the data to is our own and I know what 
i am sending and where, so it's not like I am toying around sending peoples
creditcard info to some dodgy location.

So what's happening is nothing other than peoples data being re-sent
by the server that belongs to us to a know and trusted source.
Since the data comes in via the checkout form already it is not any "less"
secure than usual.

The main issue for me was that I did not want to store the credit card
details for the second step of the processing.

Anyway, to stop me lamenting and clear this up I am not passing credit card
info around any places that are not verified or trustworthy and was merely
looking for a way to pass this information along without having to store
them on my end before the go across to the payment gateway.

I'll have another look at what I could do differently in this case. 
Usually I wouldn't to deal with an issue like this as payment information
would go straight to the payment gateway (handled there, processed there,
stored there) but in this case there was an inbetween step, which I didn't
know how to solve.

Thanks for the input.

The Sybase extension can be linked agains the commercial Sybase libs or

functions as the sybase extension.

Hi Terence,

I would handle this in a custom 404 error script.  Essentially, just have
the 404 page parse out the "joesoap", check the database to see if its
valid, and act accordingly.

Re: [PHP] Dynamic sub directory listing without redirect

[Philip Hallstrom]

Hi List,

I am trying to allow dynamic URL's for my users to remember similiar to:

www.mysite.com/joesoap

So I want to use "joesoap" in a PHP script to pick up the user's details from 
a MySQL database. If the "joesoap" does not exist in the table

I will handle that.

So basically I have one file www.mysite.com/index.php which should do all the 
processing.


I have tried with the apache .htaccess mod_rewrite, however when I echo 
$_SERVER['PHP_SELF'] I can't detect the "joesoap". It returns /index.php.


Of course the easiest way is to do something like
www.mysite.com/index.php?username=joesoap
but that is too long and complicated for our users. As we have thousands of 
users, I don't want to create actual directories.


Furthermore can this be done too (without a joesoap file):
www.mysite.com/joesoap?show_extra_details=yes

Any advice/links would be much appreciated. If I am barking up the wrong tree 
throw me a bone please.


If you are using apache, add this to your VirtualHost section for 
www.mysite.com:


  ForceType  application/x-httpd-php
  Action application/x-httpd-php /script-to-handle-every-request.php

Then in your document root, put a file named 
script-to-handle-every-request.php and do whatever you want.


You'll probably want to start by looking at $_SERVER[PATH_INFO] and go 
from there.


I do this to make urls easier to remember for our sales guys so they don't 
have to remember that www.mysite.com:8001 is their sales demo site. 
Instead they can remember salesdemo.mysite.com/philip and it redirects 
them.


good luck!

mod_rewrite can handle this easy enough:

RewriteEngine on
RewriteRule ^([a-z].*) /index.php?username=$1 [L,qsappend]
RewriteRule ^$ /index.php [L,qsappend]

$_GET[ 'username' ] will be available in your index.php when you pass
a url like:
www.mysite.com/joesoap

This can be expanded for more variables/matches by adding more
matching groups to the regex. ^([a-z].*)/([a-z].*) and so forth.

Well, you could put apostrophes or quotes around it and get rid of the
PHP Notice, and that would be syntactically correct for PHP.

What it would mean to MERANT ODBC, though, I dunno...

Though what you currently have, with lower-case, will be THE SAME to
MERANT ODBC as adding the quotes, because that's what PHP is doing for
you, and that's what the Notice is all about.

Translation:
PHP: You were supposed to put quotes on that sql_cur_use_odbc thing,
but you didn't, so I did it for you.


But this is probably NOT going to make things actually work as you
expect.

What happens next is that PHP has to convert your string
"sql_cur_use_odbc" into a number.  And that number will be 0.

So then MERANT ODBC gets the integer 0 as that 4th argument.

Which is probably NOT the number you want to send it to actually turn
on this SQL CUR USE ODBC thingie, whatever that is.

SQL_CUR_USE_ODBC is almost for sure an integer.

You could see what it is by doing:

echo "SQL_CUR_USE_ODBC has the value: ", SQL_CUR_USE_ODBC, "\n";

in your code.

If it's not 0, then adding quotes to suppress the PHP Notice is only
masking a symptom, not fixing the real problem.

I guess we'd need to know what your queries are, and if I had some
clue what SQL_CUR_USE_ODBC was supposed to be doing, it would help... 
Hopefully somebody else can chime in on this part.

The browser is showing you the JPEG as "text"

If you had the actual JPEG, and you opened it in, like, Notepad or

I think this is the wrong question...

I mean, OF COURSE, it's possible to cache them SOMEHOW.

You could toss them in your file system, or a database, insert a
machine with squid on it into the chain, or train an army of squirrels
to memorize the XML.

That last one might be impractical, as you'd need to breed super-smart
squirrels first :-)

I think you might want to avoid trying to do it the Java way in PHP.

PHP is share-none by architectural design, not accident, so that you
can scale up by throwing as much cheap/stock hardware at it as you can
afford instead of being forced to buy a single bigger hardware box in
the center for the shared data.

It would probably make a lot more sense to store whatever you use to
uniquely identify your XML source and the results in a database or
filesystem, and then compare time-stamps in some simple business logic
to decide to re-parse or serve from cache.

Yes, that does just foist off the shared-data to the database, or
file-system -- but those systems are specifically designed to handle
this task for a long time now with a lot of heavily tested and
optimized code.  PHP and even Java can't really match that level of
testing/optimization yet simply due to relative ages.

If db and filesystem are "too slow" or you already have too many
machines running this code-base, you could write your own PHP "XML
cache server" that takes an XML id and either gets it from the db/file
cache, or parses the true original, and set up your own "server" for
this express purpose and really make it scream on speed...  That's
quite a bit of work, though, and for the simplicity of the code
involved, you may be better off writing it as a C application... Or
out-sourcing that bit of code to be written with specific timing
targets for the employee to meet/beat to get their just due $$$.

Not sure specifically what broke in 4.4 for you, but here some things
that are "wrong" in your code...

1. Technically, it's Location with a capital L, I think.

2. Technically, you should provide a FULL URL to Location:

3. @$admin is suppressing an error message.  What's the error message?

4. If you're not checking that 'admin' comes from $_SESSION, anybody
from can surf to: admin.php?admin=yes

5. You are relying on "register_globals" being "on" and you shouldn't.
http://php.net/register_globals might tell you more

6. You session_register('admin') but you change $wardadmin  They
should all match.

Methinks maybe it's time for you to re-write this code :-)

If you have access to sendmail.cf on your box, you can probably do it
there...

Or, put it this way:

On MY box at home, I had to do this so the silly cable-modem provider
wouldn't block my outdoing emails, and I'm NOT a Sendmail expert by
any stretch of the imagination.

In this case, I wanted ALL outgoing email to go to a different port,
which my web/mail host has open for this very purpose.

I dunno how tricky it would be to make it only happen for specific
sender/recipient combinations etc...

Most definitely you mis-understood what it does.

Here's what it REALLY does:

Suppose when cURL loads up the URL you ask for, it gets this back:

HTTP 302 Resource moved
Location: http://example.com/new_location_for_it.htm

If you have FOLLOWLOCATION set to 1, then cURL is just gonna go ahead
and request the new Location: and get you the damn answer you asked
for.

If you have it set to 0, you only get back the output from the 302
page -- So you can figure out exactly what the server is doing,
bouncing you around from page to page, with all these silly Location:
headers, chewing up valuable HTTP connection resources, and basically
putting a big server burden on whatever you are trying to get to.

[Actually, if HTTP/1.1 is being used, and Keep-alive is working
properly on all fronts, the burden is not so huge...  But that's not a
"given" for most servers/software today.]

So I don't have any answer for what you're trying to do, except to sit
down and re-think all the bouncing around of data you're doing, and
most importantly where/how the credit card numbers are being
stored/transmitted, even in such temporary things as RAM, which is
swapped to hard drive, which is susceptible to attack.

On most shared servers, putting credit card info in SESSION data is
Really Bad Idea (tm) as every other user on the shared system can
troll through your session data with little to no effort.

This statement alone makes me think that you believe that $_POST is
somehow "safer" than $_GET and $_COOKIE.

Please purge that idea right out of your head this instant.

By the time you are on your PHP script, talking to some other server,
the data you send to/from that other server, via GET, POST, or COOKIE
is no more or less secure in any of the three.

POST data from the browser is only 1/1th "more secure" than
GET in that any idiot can see the "Location" URL and play with it, and
it takes a tenth of a clue to do "Save As.." and muck with the http://l-i-e.com/artists.htm

A long time ago, this error message would only have told you that the

Now, however, buried in this error message, is the EXACT LINE of code
where the data was already sent:

Line 6, of Consultation_test.php is the culprit.

don't use Emacs, but recall the grief it caused many a PHP beginner
from long ago on the list.

Disclosure:
I may have been the first/loudest to request that the original line of

As I am responsible for the machine, I have created the following site
with all the information you have requested: http://emailtest.altig.ca

There you will find:
email.php (the actual script)
email_php.php (the php code)
httpd.conf
php.ini

I've set up several machines like this in the past, and have not done
anything too fancy regarding Apache or PHP, and in fact, have used the
Slackware 10.2 binaries for both.

If there are any other questions you need before we can work towards a
solution, please let me know!  Otherwise, what to do next?!

Best,

You may want to consider using the Sybase drivers if they are
available as up-to-date RPMs.

Last time I checked, several years ago, they worked better/faster than
the mssql drivers.

YMMV

Definitely check $_SERVER instead of GetEnv to see if it gives you

In the old days, you'd be stuck with copying and maintaining C:\PHP
into C:\Winnt

Now, there's an Apache directive to let you define where php.ini lives.

You'd have to switch from IIS to Apache to use it, though.

But that's a good thing :-)

If one or the other database servers allows access from other than
'localhost', you can simply have two connections open, one to each db,
and XFer data in a single PHP script.



Obviously you'd need a ton of error-checking etc.

This would be, perhaps, better than dump/load if you also need to do
some business logic in there to determine which records have changed
where, and which should or should not get re-loaded etc.

Would also be handy if you need to run this script often to syncronize
the two.

But if it's a one-time dump, then presumably SQL Server can be
convinced to dump out a flat-file that you can load into MySQL as you
originally intended -- That's probably gonna be fastest/easiest for a
one-time deal.

You'd first have to show us the source code that does the email checks.

In addition, see if you can dig out the httpd.conf and php.ini that
are used on the production server, and post links to them, after
removing any data you consider sensitive.

There's no rule that the PHP binary they have laying around on the
machine for command line use has to have any real correspondence with
the (presumed) PHP Module they have loaded into Apache.

They could be different versions of PHP, with entirely different
compile-time switches, and have nothing more than "PHP" in their name
in common.

They are USUALLY very similar, but a host could easily dis-allow
certain functions in php.ini in the web environment, but your CLI PHP
can easily not be using that same php.ini, and then you get the
functions they don't want you to have.

Worst-case scenario, you could probably use http://php.net/exec in
your web PHP script to fire up PHP command line to run your DNS lookup
script.

This is a total hack and will have HORRIBLE performance penalties.

And if the real "problem" is that your host doesn't want you doing DNS
lookups in the first place, so they disabled the function in php.ini,
they're not gonna be happy to find you doing this...

Extreme Caution is called for.

[PHP] DNS lookups only sometimes

[Jadel Menard]

I have an email validation script written in PHP that works on most
Apache machines I try it on, with the exception (of course) of my production
box that it needs to go on.  This production machine is a Slackware 10.2 box,
running Apache 1.33 and PHP 4.4.0.

The script works if I call it from the command line with "php -f
filename" however, if I try to call the same script from a browser (served by
httpd) the DNS check is never made, and the script returns that the domain of
the email address is invalid.

The httpd people tell me that once Apache calls a .php page, PHP
handles the actual parsing of that page, so if these DNS queries aren't
happening when the page is called through a browser, what is changing from
when they are called from the command line?

Thoughts?

Best,
Jadel

Not given your logic above, no.

You said "If it is past the current date then I am erroring out",
therefore 2005-09-30 00:00:00 > 2005-10-07 00:00:00 will NEVER error
out, because it will never be greater than the current timestamp in
seconds.

A = 2005-09-03 = 1,128,052,800
B = 2005-10-07 = 1,128,713,278 (approx, that's actually the value now)

So A will never be greater than B, hence you're always allowing the
transaction.

Hi Rich,

Thanks for your reply.

dateexpired is: 1128052800 which translates into: 2005-09-30 00:00:00

Basically, I'm just trying to figure out when the dateexpired is. IF it is
past the current date then I am erroring out and if it's under the current
date... I'm allowing the transaction.

I would assume the following:

if (2005-09-30 00:00:00 > 2005-10-07 00:00:00)

it should error out, no?

Thanks!

I am confused... probably because of lack of sleep.

Anyway... I have code that looks like this:

{

  //dosomething

}
else
{

  //do something else

}

Using Epoch obviously

Anyway... it's supposed to read: IF the expired date is past the current
date... disallow "dosomething" otherwise... let it go.

I set the expire date to be Sept 30, 2005 and obviously today is the
current date but for some reason the "dosomething" is being allowed.

Do I have the operators mixed up here? Works is I reverse the operator but
shouldn't it work as I have it?

[PHP] Patch for Suexec for Virtual Hosts to use PHP with FastCGI

[Jason Kovacs]

Hello,
 
I am new to this list, but I thought I might contribute a patch implementation 
I've come up with and ask the other developers on the list to help me 
scrutinize its security implications.  I've posted this same message to 
fastcgi-developers list at fastcgi.org to look for feedback from them as well.
 
I've been working with Apache2, SuExec, PHP5, and FastCGI recently and ran 
across the seemingly-common problem of allowing Virtual Hosts to share a PHP 
(cgi-fcgi) binary that is SuExec'd to their User/Group.  I read everything I 
could find on the net about this subject, and the fastcgi.com archives were 
very helpful, but I was not happy or successful with some of the solutions 
presented.  I thought I would end up having to copying the php binary for every 
Virtual Host that existed and chown them to each user/group so that Suexec 
would work properly and I could stop getting permission errors.  Then I 
realized how it would be a nightmare to automate this process of copying and 
owning the php binary to the right user/group every time a Virtual Host was 
created (and I'm not that great at shell scripting).  If I wanted to recompile 
php, I would have to update all of the instances of php that now existed (which 
seemed to be getting too complex). So I finally gave in and decided to modify 
suexec.c, despite the warnings from apache.org not to do so because much 
thought had already been put into the conditions for suexec to work securely.  
However, the fact that I wanted the php binary to be shared is a special case 
from all other cgi scripts, since its user/group must be different from the 
target user/group of the Virtual Host.  So this is what I've come up with and 
it seems to fit my needs, so I thought it could help others in the same 
situation.
 
I've created a new user/group named "php-cgi-shared", which took on a UID and 
GID above 500.  My virtual hosts all reside in /home// so in my 
Apache2 configuration I set '--with-suexec-docroot' to "/home" to encompass all 
virtual hosts and their cgi-bin directories (this made sense to me, but maybe I 
don't fully understand how the suexec docroot and userdir settings work).  Then 
I created /home/fcgi-bin/ where I would later copy /usr/bin/php (built as 
cgi-fcgi) to and chown the fcgi-bin directory and the php-fcgi binary to the 
user and group of "php-cgi-shared".  I've read some 3rd-party changes and 
patches to suexec.c that chose to completely ignore the check for the 
SuexecUserGroup UID and GID to match the UID and GID of the CGI file and its 
containing folder. However, I thought this was a too lenient and allows 
security holes, so I left that code as it is but added a custom hack of my own. 
 I've hard-coded the custom user/group of "php-cgi-shared" into the suexec.h 
header file, and within the code checked to see if this was a valid user/group 
on the system and obtained its UID and GID.  If the UID/GID of the target 
program and folder do not match the SuexecUserGroup (as done in the original 
code), then I additionally check if they match my "safe" UID/GID obtained from 
the "php-cgi-shared" user/group.  If a match occurs, then I allow the suexec 
program to proceed and not exit with an error.  So then when FastCGI passes the 
SuexecUserGroup from a Virtual Host to the Suexec wrapper, it will spawn a 
dynamic instance of the php-fcgi binary running as the user/group of the 
virtual host.  Likewise, I run a static instance of this php-fcgi using 
FastCgiServer with the -user and -group set to "php-cgi-shared", and not 
"apache/www/nobody" because those users are below the UID/GID of 500 that I've 
set as a minimum when building Apache/Suexec.  My assumption is that this 
fcgi-bin directory and php-fcgi program are the only two files that are owned 
by "php-cgi-shared", as set by root, and no other cgi's will ever take on this 
special privilege that suexec now allows.  This seems to be a valid solution, 
unless I don't fully understand how all of the components work together 
correctly and securely.  Please tell me otherwise if I am wrong.  All I know is 
that this setup is now working the way I want after many days of frustration, 
it keeps things secure as far as I can tell, and requires little to no extra 
maintenance in the future.
 
My httpd.conf file has the following directives that apply to 
PHP/FastCGI/Suexec (I built Apache2 using its default directory/file layout):
 
User apache
Group apache
...
LoadModule fastcgi_module modules/mod_fastcgi.so
AddType application/x-httpd-php .php

   Alias /fcgi-bin/ /home/fcgi-bin/
   FastCgiIpcDir /usr/local/apache2/logs/fastcgi
   FastCgiWrapper /usr/local/apache2/bin/suexec
   FastCgiServer /home/fcgi-bin/php-fcgi -user php-cgi-shared -group 
php-cgi-shared
   
  SetHandler fastcgi-script
  Options +ExecCGI
   
   AddHandler php-fastcgi .php
   Action php-fastcgi /fcgi-bin/php-fcgi

 
Please respond with your comments on my method, and if it's generally correct

Is this what happens:

1. User enters payment data
2. XML check that payment data is OK
3. redirection to a page (on another site?), where for some reason the
payment data is required again (why?).

This sounds like a mixture of two ways of implementing online payments.
Forgive me if I'm telling you what you already know, but in general I
believe things work as follows:

1 The whole process from payment to verification takes place on the payment
provider's server
or
2.  the whole thing takes place on your server, with some inline (XML in
this case) communication with your payment provider to verify the card
details.

You seem to be doing a bit of both, or have I misunderstood?
Why do you need the payment details on the third page? If you don't actually
need them, then the security problem goes away, and you can use the session
object or whatever to persist the customer data.

Does this help?

The solution is to fix the SOAP package. Instead of:

make it:
$ret = $serializer->...
return $ret;

This notice was added because PHP has memory corruption issues when

[PHP] Question

[Sven Simons]

I've installed PHP using the windows installer 
I try to open then php pages containing the following script :
";
 
 echo "Server IP Address: ";
 $ipx = getenv("SERVER_ADDR") ? getenv("SERVER_ADDR") : 0;
 echo !$ipx ? "UNKNOWN" : $ipx;
?> 
It works and gives me a correct current IP address
 
When manually installing PHP it always gives me the status UNKNOWN.
 
The only difference I've seen is that the Windows installer uses the
php5ts.dll for ISAPI filter while the manually installed php uses the
php5isapi.dll.
I know that the PHP is working (when manually installed) because this script
works :

 
The only strange thing is that the phpinfo says that the ini file is located
in C:\Winnt although it is not there (when installing manually it is in
C:\PHP)
 
How can I make the IP address script working when manually installing PHP ?
Or is it really so unsafe to use the windows installer on a online server?
 
Sincerely,
 
Sven

Hi,

you have to use



because include goes to buffer, print's go to buffer and on the end the 
buffer is automatically flushed out. So it's the 2x - once for include, 
once for "print $contents"


Simple eh?

[PHP] PHP 4.4.0 references problems when using PEAR::SOAP

[Denis Gerasimov]

Hello list,

I am facing serious troubles when using PEAR::SOAP with PHP 4.4.0 while it
works fine with PHP 4.3.9.
PHP 4.4.0 produces many notices like these:

Notice: Only variable references should be returned by reference in
C:\PHP4\PEAR\SOAP\Value.php on line 118 
Notice: Only variable references should be returned by reference in
C:\PHP4\PEAR\SOAP\WSDL.php on line 668
Notice: Only variable references should be returned by reference in
C:\PHP4\PEAR\SOAP\Value.php on line 118

and so on.

What is the problem?

Currently I have rolled back to version 4.3.9 but this problem will appear
again after upgrade, of course, - is there any solution (say, php.ini
setting etc.)?

Have a great day,
