RE: [PHP] About Session And Cookies

[Warren Vail]

Kelvin,

Sessions is just one of the items recommended for an e-commerce website.  I
seem to recall that if cookies were not enabled that there was a way of
passing the session id in the URL as a "Get" parameter.

Basically you will store the items to be purchased in a special table and a
shopper ID or cart ID number will be assigned with the first selected item
and needs to be retained to be able to recall the selected items when the
shopper is ready to check out.  A session variable is a good place to store
this id, but it could also be passed in the form as a hidden field.  A
session is also a convenient way of providing a generic storage of the items
to be purchased, separate table is possibly more common.  You don't have to
be too concerned about security up to the point where someone begins to
check out when you begin gathering personal information from the buyer.
Give it some thought, but I suspect in most cases that if someone were to
capture a session at this point, the worse that could happen is they would
both order and pay for the same items.

When you gather personal information it becomes a different matter, and at
this point I would first recomment you consider passing your order items to
a resource like paypal and let them collect the personal information.  If
that is not possible you will want to switch to SSL communication with the
browser before when you present your form for the personal information, and
even in this mode I would recommend that if you detect errors on the forma
and need to represent the form for the buyer to correct info, toss away the
credit card info and have them reenter it.  You do not want to store this in
your session, or anywhere on your system without really secure incryption
(I'm talking about the DB side here, not the SSL channel to the browser).

Once you begin collecting personal information (and this is not limited to
the obvious like social security numbers), you should make sure the session
cannot be hijacked, to prevent identity theft, this is where cookies work so
well.  Anyone who doesn't allow cookies is forcing you into a situation
where you must expose their session information in the URL or a hidden field
on the form where it can be hijacked, in which case I would refuse to have
them as a customer, it's not worth the risk.

Hope this helps,

Warren

So it's like email, but you can only send messages to other people that

Hi,
I installed libtool 1.5 and tried again. The libphp.so was not created

[PHP] About Session And Cookies

Re: [PHP] cant get if logic correct..

[Wouter van Vliet / Interpotential]

is_integer probably wouldn't work, since you're dealing with strings here.
Your best friend here would probably be 'is_numeric' which would return true
on both the string '1' as the integer 1 true. As well as 1.1 and '1.1'. The
only one solution I could think if would be:

   preg_match('/^\d+$/', $stnr);

1. No captcha works 100%.

3. So, if you need a captcha, don't make it difficult. A simple 1 + 1

This advice is offered after going down that road, see here:

You want to add the ungreedy modifier...

2(-3) steps:
1. Make it _un_greedy (preg_* are greedy by default, so "/'(.*)'/U" will 
match foo''bar''glorp, making it ungreedy (/U modifier) would make it 
match just foo

2. Make it fetch _all_ matches, use preg_match_all
(3. there's no need to escape single quotes in this string :))

The following works:
preg_match_all("/'(.*)'/U", "'foo''bar''glorp'", $matches);
print_r($matches);

Given the string 'foo''bar''glorp' (all quotes are single quotes)I had

Instead of switch try with if condition as follows

Now it works..

You can write the code to display the result how you want.. but you cant

Any ideas?


I'd be interested to know this too. There are a few places I can think
of where it would be quite a nice addition.

So you want to read from stdin byte for byte?  If so, I suspect your
problem is in the normal stream buffering. 

I don't know if terminal IO is really feasible with PHP. Maybe you
should check out the ncurses interface?

RE: [PHP] apache/php with sybase12.5

[ROUKOS Michel]

Hi,

If I place the following line in httpd.conf

LoadModule php5_module "modules/libphp5.so"

I receive this error:
Syntax error on line 232 of /usr/local/apache2/conf/httpd.conf:
Cannot load /usr/local/apache2/modules/libphp5.so into server: ld.so.1:
/usr/local/apache2/bin/httpd: fatal:
/usr/local/apache2/modules/libphp5.so: open failed: No such file or
directory


During the configure, make and make install steps, I received no errors.

find / -name libphp5.so returned nothing.

I did the same steps with mysql, and the libphp5.so was created. Also
please note that the sybase servers are remote. I have only the client
directory on that server (/opt/sybase)

Thanks.

That's about all I had for bright ideas on this one, sorry - like I

Hi All

I am having a problem getting stream_set_blocking to work the way I

When a file descriptor (stdin) is non-blocking, any read() will not
block and wait for data to become available, but will return right away
with or without data.  Set the fd to blocking to wait for data.


/Per Jessen

  


This is true which is why I put fread() into a loop. If you look at the 
output you will see that data is available even before the first 
iteration. PHP only seems to recognize this though when the enter key is 
pressed. If I press the enter key while blocking is off then it finds 
the data. Is there any way to get the PHP to recognize that data is 
available without pressing the enter key?

Did you also place the following line in the apache config?

LoadModule php5_module "modules/libphp5.so"

If you sure there were no configure or compile errors when building PHP
try and locate libphp5.so on the server. And copy it to the module dir.

find / -name libphp5.so

Hi,

I am integrating httpd-2.0.59 with php-5.2.1 and Sybase 12.5 on a
solaris 8 machine. I followed these steps:
Install apache:

./configure --prefix=/usr/local/apache2 --enable-so
make
make install


PHP configuration:


I edited this file php-5.2.1/ext/sybase_ct/ php_sybase_ct.h and changed
this line:
#define CTLIB_VERSION CS_VERSION_100
...to...
#define CTLIB_VERSION CS_VERSION_125

Then:
./configure --with-apx2=/usr/local/apache2/bin/apxs
--with-sybase-ct=/opt/sybase/oc12.5-EBF11486/OCS-12_5/ --enable-bcmath
--enable-calendar --enable-ctype --enable-exif --enable-ftp
--enable-trans-sid --enable-shmop --enable-sockets --enable-sysvsem
--enable-sysvshm --enable-wddx
make
make install


then added these 2 lines in httpd.conf:
AddType application/x-httpd-php .php .phtml
AddType application/x-httpd-php-source .phps


When I access test.php, I am asked to download the file - meaning php is
not working well. I also don't see libphp5.so under modules/ directory.

test.php is locate under htdocs/ and has this content:

You can try:
 unset($a-b)

Or change isset() to empty().

empty() catches more than isset() e.g. '' (empty string), false, 0 etc.
are considered "empty". Depending on your logic it can still be very
useful. It is a language construct rather than a function so it's also
efficient.

[PHP] Re: Which CAPTCHA is the besta?

[Al]

Here's a simple one you can hack to fit your needs.

This a file for generating the captcha image.
	$src = @imagecreate($width, $height)  or die("Cannot Initialize new GD image 
stream");

$background_color = imagecolorallocate($src, 200, 200, 200);
$text_color = imagecolorallocate($src, 20, 20, 255);

imagestring($src, $font, 3, 3,  $num_str, $text_color);

imagejpeg($src);
imagedestroy($src);
?>

This is the code snippet for your client page:

/**
 * This is a typical use of the catcha code
 *
 *
 */
// Security Code ***/

$sid= session_id(); 
//See if session handler exists

	if(empty($sid))	session_start();			//This also places a session cookie, if 
enabled by client's browser


	$scode= rand(100, 999);		//pick the range as you like. 100 to 999 is 
probably sufficent


$_SESSION['scode'];

	$prev_scode= $_SESSION['scode_show'];		//This is the scode the user saw 
previously and was to enter
	$_SESSION['scode_show']= $scode;			//Set an new scode; this is used by 
make_scode_img.php for the label graphic generation


$scode_passed= (isset($_SESSION['scode_passed']))? TRUE:FALSE;
//print_r($_SESSION);
	if(!$scode_passed && isset($_POST['scode']) && $_POST['scode']== $prev_scode) 
$scode_passed= TRUE;  //If not set, see if passed


$scode_txt= NULL;   //So can be used without a if() test

if(!$scode_passed){

$len= strlen($scode)+2;
$scode_txt .= <

the solution has been found. array_key_exists() can actually be used
on objects, and yields the correct result.

Seems your asking for something similar to perl's exists() function..
Best I can come up with is...

$a->b = null;

if (is_null($a->b) || isset($a->b)) {
print "yes";
}

Thanks Edward - [1] makes perfect sense.  I think I'll just store on it
disk instead and reload when necessary.

I think it wont directly but it should be solvable by creating an class
which extends DomDocument but also implements __sleep/__wakeup calls to
serialise itself correctly. This may add significant overhead and in
practice you may be better just storing the XML itself in the session
and create a DomDocument object only when you need it.

YMMV.

I don't think it is possible due to the way PHP handles the XML data [1].

This is from 2002 / PHP 4.3 but a comment [2] in the PHP manual for
SimpleXML seems to suggest it is still the case. You could probably get
around it by using a string representation in the session variable.

[PHP] a DOM object in $_SESSION ?

[Per Jessen]

Does anyone know if this works?  I've been trying out a few things, and
it doesn't seem to work.  I.e. the object is there, but the contents 
aren't. 


thanks

If you take a look at the comments at the manual page for
mssql_connect [1], you see that a lot of people have reported problems
with, but there are also some solutions. I don't know if they work,
because I never had any MS SQL server (MySQL rocks ;-)), but the
second comment seems helpful.

Warning: mssql_connect() [function.mssql-connect]: Unable to connect
to server: (local)\SQLEXPRESS in C:\wamp\www\test\test.php on line 8
Couldn't connect to SQL Server on (local)\SQLEXPRESS

this is my connection script
