RE: [PHP] Select Values Didn't Get Passed in From Two Different Forms

[Edwin]

Hi Adam,
I am not sure this would help but does echo command end with semi colon ;
?.  value=""/> 

Maybe the echo is having some issue? Else, you could try passing the
variables as method = get and view the variables in
Ur address bar....

Edwin.

Re: [PHP] hiding passwd in cmdlines that appear in the process list

[Edwin Barrios]

Hi .!
First of  all . Pardon if my last mail was not undestable !!

Then Richrad said that, the following is a cons  of my solution :

"  A simple debug statement to dump out all of ENV / $_GLOBALS will expose
the password. So   you have to ask yourself if you and all your employees
and all the scripts you ever install, including any forums etc, are for sure
never ever going to dump that password out in an attempt to debug something
else.  " ...

This is not triue because a shell vars declered on a shell is only exposed
to its subshells, that means that only exec's and system functions calls
into the php itself resive those vars declared into the php !

You can see this argument in the following code

";
 system("env");
 echo "";

 putenv("DBNAME=sidf");
 putenv("DBUSER=p");
 putenv("DBPASSWD=p");

 echo "NEW ";
 system("env");
 echo "";

?>

and reloading these a couple of times.

This solution, as most good ones, has pros and cons:

Pro:
Does keep the password from being exposed in the normal course of
operations.

Con:



This is not triue because a shell vars declered on a shell is only exposed
to its subshells, that means that only exec's and system functions calls
into the php itself resive those vars declared into the php !

You can see this argument in the following code

?php
 error_reporting(E_ALL);


 echo "OLD ";
 system("env");
 echo "";

 putenv("DBNAME=sidf");
 putenv("DBUSER=p");
 putenv("DBPASSWD=p");

 echo "NEW ";
 system("env");
 echo "";

?>

and reloading these a couple of times.

A simple debug statement to dump out all of ENV / $_GLOBALS will

expose the password.

So you have to ask yourself if you and all your employees and all the
scripts you ever install, including any forums etc, are for sure never
ever going to dump that password out in an attempt to debug something
else.

For a solo developer or even a small team, with all custom hand-coded
stuff, this is pretty easy.  But once your application blows up and
you have a larger team, or you start caving in to client demands to
install badly-written forums/carts/blogware, you are open to a
potential security hole which:
  has two seemingly unrelated contributing causes
  the two causes can be years apart in time
  both are simple straight-forward "obvious" Right Things to do

So you have to weigh carefully the Risks, and DOCUMENT what you did
and DOCUMENT what *not* to do in the future to expose this sensitive
data.

Re: [PHP] hiding passwd in cmdlines that appear in the process list

[Edwin Barrios]

Hi !.

I don't know if my solution is better or not. but in one of my programs i
had to make a backup online then my solution was to use shell vars to put
important information like db_password . When we use putenv function those
var only exists on the current shell and on its subshells. In your case the
following code :

Re: [PHP] Multi-threaded port listener

[Edwin Barrios]

Hi.

If you want a separate script execution, you can use inetd o xinetd to
listen for you that port.
When inetd got a connection execute your php script, one execution by
connection.

I think that it is more usefull to create your  own responser server with
php using forks !. But using inetd has the advantage that you can use
tcpwrappers.

Asunto: [PHP] PHP 5 + Apache 2 on Windows: ms sql extension problem



 Hello All,

I had a problem with a Win2003 server, IIS6 and PHP 5.1.2. The MS SQL 
extension was not working. I did not get an answer, but some people 
suggested me to use Apache. Now I installed Win 2000 server, Apache 
2.0.55 and PHP 5.1.2. The same computer has Microsoft SQL Server 
installed. I have only these lines in my php.ini file:

extension_dir="C:\PHP\ext"
extension=php_mssql.dll

I checked phpinfo() and it tells that my php.ini file is at the correct 
location (C:\winnt\php.ini.) I can load other extensions. Another 
example: if I add "php_curl.dll" then I get a "libsleay32.dll not found" 
error message when I try to restart apache. But I do not get any error 
message about the php_mssql.dll. It is just not loaded. I'm sure that 
all the ms sql client libs are installed, because this is the same 
machine where the ms sql server is running. What can be the problem? 
Please help me. My bosses are killing me because I could not solve this 
problem for weeks. :-(

Thanks,

  Laszlo

Or if you have header.inc.php and the body tag is global then in your

Window.onLoad=function(){

Hi.

It is not possible to do that using PHP but you can use JavaScript 
instead. I recommend the function focus(). For example:


Check this tiny tutorial: 
http://javascript.internet.com/page-details/focus-onload.html

Did you already remarked that http://www.google.com is using this 
function to automatically set the focus on the search field.

At a "much reduced resolution"? Try scanning some photo, say
an A3 size photo, at 72ppi. Then, try printing that at 600dpi on
the same A3 size paper and see what you get.

Add to that that some have 8(+paper color). And that not all

That'd be nice. But as somebody pointed out earlier, one of the
advantages is that PHP can run as another user instead of as
the apache user. (Of course, it's still considered rather slooow
though.)

Anyway, there are some more info here:

Remember, Miles, *your* $Web_Hosting_Company decides
(or better yet, *you* decide) whether PHP5 should run as
CGI or as an apache module. ;-)

I think it was also pointed earlier (somewhere) that it's the

I really have no idea (read: lazy to check now ;-) ) what
"CPanel" is. If it is a program written in PHP (4?), they could
just "fix" it to work with PHP5 -- CGI mode or not.

But of course! You're right (^_^)

I was thinking more of "if" or "for example" as in "for example
you have a 25x25-inch monitor..." But, yeah, a 25x25-inch
monitor is rather ridiculous, I guess.

Reading the surrounding sentences, I think I can see where
you're coming from. But, the above statement is a bit
confusing.

There is a reason why it's called "pixel per INCH". And it
definitely have something to do whether your monitor
is set to 800x600, 1024x768, etc.

A 15-inch monitor at 800x600 will have around 53ppi x 40ppi
(800 pixels divided by 15 inches, etc.) and *the same* monitor
at 1024x768 will have around 68ppi x 51ppi.

If your 15' monitor is normally setup at 1024x768, everything
(images, etc.) will look a bigger if the same image is viewed
using the same monitor at 800x600. This happens because
the pixels are now "bigger". (One image "pixel" is now compose
of many physical dots on the screen.) But, I guess, you already
knew that. (^_^)

Hmm.. I wanted to say check http://www.php.net/eval but
then again, someone very famous in this group once said:

So, maybe, I shouldn't even recommend that. (^_-)

Okay, if it was scanned at 72ppi then you can't really print
it out again even with a near-similar quality. However, having
an image with a 72ppi does NOT necessarily mean that you
have an image unsuitable for printing.

> PPI or pixels per inch is a printing term.

Last time I checked, "dpi" is the printing term. (^_^)

  dpi (dots per inch) -> printer
  ppi (pixels per inch) -> monitor/screen

This really depends on how big the image is to be printed.
Besides, an image/photo taken using a digital camera (at
least mine) always defaults to 72ppi. BUT that does not
mean that it will come out badly printed at 300 dpi -- it
all depends on how big is the size (setting) of the picture
when I first took it.

True. This is basically because most monitors/screens are
actually at or near 72 ppi. "screen" !== "printer" (^_-)

See if you have ImageMagick installed. You could
probably use the "identify" command to find the
info you need. For more information:

  $ man identify

Of course, this solution is not *in* PHP but you can
invoke that program inside your PHP scripts (^_-)

No, nothing wrong there, I think.

But there are other differences. (Like some functions not
working, etc.) Pros and cons, one might say. Anyway, here
are some results of a quick google search:

Re: [PHP] Re: Using GPG in Safe Mode

[Edwin Barrios]

Hi, emil

Using "safe_mode_exec_dir", it's a solution if  you has access to your
php.ini or http.conf, because it's a PHP_INI_SYSTEM var. For these reason
you can't set this var with ini_set() function on a php script.

If your ISP has a very restricted setting, i think that the solutions that
"comex" comments it's a good one, it'sn't my prefered solution by security
issues.

P.S.D
i never have proved if setting PHP_INI_SYSTEM vars it's posible on a
.htacces file.

Re: [PHP] Using GPG in Safe Mode

[Edwin Barrios]

Hi emil !

If you are using gnupg comand line, there is not way on PHP-safe mode.

The only way that i know to wrap around this problem it's install
pecl extension package calls gnupg (http://pecl.php.net/package/gnupg). This
extension use libgpgme that bind all gnupg comand line options, then it
don't have problems with safe mode.


i don't know if this tips it's useful in your case, but it's the  only
solutions that i know.

Hello Gustavo. !

Thanks for  your suggestion, that  book it's  a interesting material to
learn more advanced features of PHP5 and to begin on the C extentions world.

The chapter 15 only take a look to extends PHP5 funtions, but there is none
section on how to create a PHP5 Class on the C extentions.

Do you know how to do that ?

Hi,I'm a PHP web programing, but i wanna learn how to develop php5
extensions on C/C++. I found php5 a good language to apply Objects
programing, and it has very usefull examples of OO extensions as SimpleXML,
DOM, Sqlite; for this reason i wanna develope my extension following those
styles of API's .
I've read some docs about creating a php extension that appears as new
functions on PHP, but i can't find info to develop extensions that appear as
classes on PHP .

Thanks for your help. I'm really interested on this topic, especially to

Re: [PHP] Inherit Methods

[Edwin Barrios]

Hi !

you have to defined protected $var.

 This is a example  where php5 OO model has a little ambiguities.
Thing a few in your  problem !, on de child class scope $var it's
private then when yo execute printVar(), you aren't executed on parent
scope you are calling a copie on child scope, then you don't have
access to $var. Only when you use parent scope throw
parent::printVar() , you realy calling the parent class instance into
your child then print result.

Then when you want to have a variable for being used on a public
inherit method you have to defined protected

[PHP] Performace and segfault errors with Php5 + Apache 1.3.x + linux-2.6.x

[Edwin Barrios]

i'am developing  a web framework SifEngine (Secure Web Inteface
framework) that implement MVC applaying the security ideas from
http://phpsec.org. I'am using DomXML, Sqlite, Mcrypt and PostgreSql.

After  of post my development on the internet ( i have been thinking
to post on PEAR ), i made simple tests of aplications with my
framework. During the implementation, i used Slackware 10.1 with
kernel 2.4.29 + php5.0.4 + Apache 1.3.2, with no problems. I didn't
detect  performace problems or segfaults by apache.  Then i decided to
do the same test but with kernel 2.6.10, wating that no problems
occur. However my expectation, on this new configuration all the
aplications develped with my framework, had performance issues or in
the worst situation produce apache forks  to be restarted, or a lot of
apache forks.

i don't undestand why this occur, i try to use valigrand to verify
memorie lacks without results.

Someone can help me, with this problem !

On this moment i'm using SIfEngine, to implement my proyects only on
kernel 2.4.x !

Re: [PHP] returning info. from a form selection

[Edwin Barrios]

 Hi . !
 
 what you want it's  recive values from a "select". !!!
 
 First a select input send ( when the form is submitted ), the value of
 the selected item, then
 the php script that  it's the form action recive, a on post  or get a
 variable with the name of  the select input with this value.
 
 Then  you have:
 
 This the html source
 
 
 
  Purchase
  Construct Home
  
 
 
 
 
 On the php source:
 
 
 
 
 That it's all.

[PHP] Performace and segfault errors with Php5 + Apache 1.3.x + linux-2.6.x

[Edwin Barrios]

i'am developing  a web framework SifEngine (Secure Web Inteface
framework) that implement MVC applaying the security ideas from
http://phpsec.org. I'am using DomXML, Sqlite, Mcrypt and PostgreSql.

After  of post my development on the internet ( i have been thinking
to post on PEAR ), i made simple tests of aplications with my
framework. During the implementation, i used Slackware 10.1 with
kernel 2.4.29 + php5.0.4 + Apache 1.3.2, with no problems. I didn't
detect  performace problems or segfaults by apache.  Then i decided to
do the same test but with kernel 2.6.10, wating that no problems
occur. However my expectation, on this new configuration all the
aplications develped with my framework, had performance issues or in
the worst situation produce apache forks  to be restarted, or a lot of
apache forks.

i don't undestand why this occur, i try to use valigrand to verify
memorie lacks without results.

Someone can help me, with this problem !

On this moment i'm using SIfEngine, to implement my proyects only on
kernel 2.4.x !

Thanks !

Just want to add/emphasize one thing regarding this point:
When I try to find out something, I usually spend time 
googling and reading the archives, it's really quite 
annoying to read/scroll from bottom to top--this is not how
people learned to read. (At least, I hope not :)

Also, it's good that we're not writing programs from bottom 
to top as well... imagine that! (That'd worst than "spaghetti

When the release for RC1 was announced, this was also

  "XML support has been completely redone in PHP 5, all

I guess that includes libxslt so most probably you'd be

Just an idea... How about doing something like this:

Retrieve data from the db(utf?) then convert it to the

  ex. for EUC-JP

db (utf) -> html (EUC-JP)

And why would they need to recover/discover them?

If other users of the server can "see" your script(s) that 
holds the information (username/password) for your db, 
then they don't even have to know the real password--
they can just used the hashed ones to access your db.

Or, maybe you want to explain more? :)

You mean the password for the database? Why would the user 
need that? If the users need a password to access the site, 
then create one for the *site*. Only you and your scripts 
need to know what the password for the database is...

Then there's a problem with your code. Check $username first
before you use it. Also, if you're using $_POST then you should
use $_POST['username'] instead of $username.

Use an absolute URL for header("Location ...

And, your "echo" shouldn't come before your "header". Again, you
can check the manual/archives for more info...

And, maybe there's something else, I didn't really check
everything :)

Hmm... that's a pretty scary setup. You can ssh as root? Without
a password? I wouldn't want that kind of setup even if I'm using
"authorized_keys" and stuff. Anyway...

Most likely it's because when you're running your (php) script
you're NOT running as root. Try running the script as root (from
the command line) and see what happens.

Why not? A minute for each and you can finish it in less than a

Or, try stylesheets: (And since you mentioned 98 or XP, this

Your query wouldn't even be executed if you have a "parse error"
on your script. (So, it's not even possible for MySQL to "put bad
information into the database"...) Single quotes, double quotes,
semi-colon ought to be checked if one has "Parse error: parse
error, unexpected T_VARIABLE in blah blah blah"...

Try searching for "DocumentRoot" and/or "UserDir":

Or check the comments inside your httpd.conf file. I'm sure

Btw, "Sites" corresponds to "public_html" in default (Red Hat)

Instead of "generating" the menu(s) each time, why not create a static

Okay, this is just an idea.

Use file() to put everything in an array.

  http://www.php.net/manual/en/function.file.php

Then find a function here that would let you check the first
four characters.

  http://www.php.net/manual/en/ref.strings.php

Loop through the array created by file() and process each
line accordingly (whatever it is that you need to do with
each line).

I'm using the browser but not the email and news client so

In the above, you're basically asking

  if (all of these are TRUE) {
do my stuff...
  }

So, if even one of those is "0" then it won't do your
stuff...

Well, this

  if ($_POST['accid'])

is asking something like

  if (TRUE)

so if the value of $_POST is "0" then it's FALSE. If the
value is "1" or "a" or "Edwin" then that would evaluate to
TRUE.

Whereas this one

  if ($_POST['accid'] != "")

is asking something like

  if the value of $_POST is not equal to "" then...

So, since "0" is not equal to "" then the result would be
TRUE. If the value "1" or "a" or "Edwin" then that would
STILL evaluate to TRUE since those are not equal to "".

Not sure if I had explained this well since I'm starting to
have a headache trying to figure out how to explain 'What is
"TRUE"?' "Not 'FALSE'". "Then, what is 'FALSE'?" "Not
'TRUE'." "??."

It *should* since it's based on FreeBSD 5 ;) I didn't try

Works here even with single 0.

I think it'd be scary if there's a certain doctor who'd give you a

Don't be surprised if your headache is gone the next morning.
I for one am also very interested in hearing possible solutions.
I can think of multiple situations in which checking to see whether a
user inputted kanji or kana would be very useful indeed.
Like for example?

 And I hope to
learn more by further discussion of the PHP coding required. It would 
be
a shame if that potential learning was obscured or lost in off topic
theorizing about the origins of the Japanese language.
First, I'm not theorizing. They're written in history books.

Optimistically looking forward to seeing more technical discussion on
how to accomplish this.
Secondly, didn't I mention that this was recently brought up in the
Japanese PHP Group ML? And there's really NO easy solution for this?
  http://ns1.php.gr.jp/pipermail/php-users/2003-October/019236.html

In fact, that "problem" is already an FAQ in that ML--and other MLs as
well since "the need" is not limited to PHP programmers only.

I disagree with the term "simplified kanji".
  regex - regular expressions

  Um, what's so "regular" about it again?

  The kana may have been
derived from kanji and evolved over the centuries, but they are no
longer kanji in the sense that they carry any intrinsic meaning by
themselves.
?? Who said that they are kanji?

Kanji are Chinese characters whereas kana are Japanese characters.

  Nor can they replace kanji in meaning and function.  They
are just phonetic alphabets.
Did I say otherwise?

"Brain-dead format" compared to JIS? Hehe, maybe you're
confused ;) Besides, I guess, more than half of Japanese
sites are written in shift_jis.

Result of a quick Google search:

  http://www.io.com/~kazushi/encoding/

Anyway, the easiest way (I find for now) when working with
PHP and Databases (MySQL, etc.) is to use "euc-jp". There are
times though that you are "forced" to use "shift_jis" e.g.
when working with sites for i-mode's browsers. If that's the
case, just use the mb_* functions to convert from euc-jp to
shift_jis...

Well, I'm sure there's a very good reason why the dictionary
I quoted called it "simplified kanji". In fact, there's a
very good why many--if not all--the books that talks about
the subject call it the same way.

Japanese didn't have a native system of writing so they
borrowed from Chinese characters. Those Chinese characters
were used *phonetically* and the meanings were ignored. In
other words, one can say that, during those time /even/
kanjis did NOT have any meaning for the Japanese (person)
since the characters were just used phonetically.

Since each Japanese word had to employ several Chinese
characters, which requires a large number of strokes, they
decided to simplify this bothersome process by using a
cursive, simplified style of kanji.

Then, (just to make the story short) during the Heian period
(794-1185), the simplified characters underwent a further
simplification. Thus, "hiragana" (and a little later,
"katakana") was born.

Actually, just by observing how the "kanas" are written,
you'll notice that:

  * The hiragana and katakana for "na"
came from the kanji "na" in "Nara"
(Nara Prefecture).
  * The hiragana and katakana for "yu"
came from the kanji "yu" which means
reason, cause, etc.
  * All hiragana and katakana has a
corresponding kanji from which
they're derived from.

Now, back to the future...
