RE: [PHP] PHP5 - instanceof [SOLVED]

[Martin Towell]

ah yes, of course "instanceof" means you're working with an instance of an
class - 

Pity there's no equivalent for classes :( oh well, I'll just have
instantiate the class first then do the checking.

Thanks

[PHP] Multiple Socket's at one time

[Terence]

Hi All,

A simple example I got from the manual:

$fp = @fsockopen ($address, $port, $errno, $errstr, 5);
if (!$fp) {
   echo "Oops";
} else {
 echo "Ok";
  fclose ($fp);
}

Can someone point me in the direction of being able to probe multiple ports
at the same time? (multi-threading or forking concept) We are looking at
creating our own monitoring service to test if ports are open on our
servers. If we scan every minute, and each takes 5 seconds, that only allows
us 12 such ports before we overflow into the next minute. Unless someone
else has a better solution that we can implement?


Thanks!
Terence

Re: [PHP] PHP5 - instanceof

[Travis Low]

An instance only exists after it has been instantiated.  So you can't know 
anything about an instance (== an object) beforehand.  It's like knowing a 
person before they are born.

Maybe you mean you want to determine if class B is a subclass of class A. 
That's the same problem again.  Even if PHP5 had a Class object (a la Java), 
you'd have to instantiate *it* in order to find the relationship between class 
A and class B.  Prior to that point, you only have text strings to work with. 
I suppose you could search the text of the file for "extends FooBar" or something.

cheers,

Travis

If you have something like this:


This would echo "BA". That's good, I understand that.

Now the question: Is it possible to determine if B is an instance of A
without instantiating it?

we're looking for something that will allow our users to be able to search
through the profile information, to find other users with the skills that
they need. The goal is to be able to support a distributed team of users.
this would be a way of allowing them to kind of stay in touch.

we'd also prefer that the app have a good admin function.

if need be, we could always rip this function out of an existing app if you
know of one, and create a stand alone app

Of course we'd also prefer that the app be "open source"...

The POST data basically sits in STDIN for the webserver, it will
just sit there unless somebody like php reads that data and does
something with it.

By default php streams the STDIN to a file so your just dealing
with buffer sized ~2K-4K.  enabling this option makes php put the
contents into memory, thus leaving open the possiblity of someone
using up all your memory and bringing the machine to a standstill
till, then when swap space runs out.. watch out! :)

If it was always enabled, it sure would make a DoS attack easy. I'd just
send lots of huge POST requests to any PHP script on your server. Hope
you have "migs and megs of memories," as Strong Bad would say. :-)
   

Isn't this potentially a DoS attack vector anyway? I don't need a server

Well if you disallow post, you will have to use get for things like 
login in - insecure. And you will be limited to about 1024 bytes of data 
on most systems and you can't use file uploads.

I guess you would know how to how to create malformed packets. Doing a 
dos attack on a PHP script that accepts POST you only need about 10 
lines of code, don't need to know how to create malformed packets, and 
you don't waste your own bandwidth.

I tried logging in to mySQL through the terminal Through the command

I can run php scripts from a browser - connect to databases, retrieve

and though I haven't tried I doubt I'll be able to create, delete, or

Hi all,

I need to build a site search engine but the problem is. the site isn't

Anything out there?

Remove the line adding 'Any' at the beginning of your code and use
array_unshift() to add it at the end.
   $eventList = array();
   $dbh = db_open($host, $user, $password, $database);
   if($dbh) {
 $sthdl = db_get_event_data($dbh);

   asort( $eventList );
   array_unshift($eventList,'Any');
do you really need to maintain the numeric keys to the array by using
asort() instead of just sort()? If so, this may not work. You may be able to
use array_splice($input, 0, 0, array('Any')) or array_merge().

yeah it is rather undocumentated, probably because of its current
EXPERIMENTAL status.

the actual call should be this:

$timeout = array('sec' => 5, 'usec' => 0);
socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO, $timeout); 


The idea of using the blocking method and letting the read() call
to handle the time, makes you're loop simplier and not have to
manage the time elapsed.

If you want to manage the elapsed time yourself (nonblocking),
you'll have to restructure your loop because the read() will fail
if no data is available.  Not to mention it will be rather
unfriendly for your cpu since you're going to have a loop that
continue to run for 5 seconds.  

Another option would be to use the fsockopen/fread tools.

If you use blocking and then set the timeout for the read, you can
just check for socket_last_error() after the loop.
socket_set_block($socket);
socket_set_option($socket, SO_RCVTIMEO, 5000); // milliseconds iirc

  //...

if ($error = socket_last_error($socket) ) {

Re: [PHP] PHP Session Handlers

[Paul Higgins]

Ok, thanks.

One other question.  If I use the example I cited earlier, are the session 
values still stored in a flat file?  Or do I have to replace that with 
database entries?

Thanks.

No, you'll just use sessions as normal and these functions will be used by
PHP when needed. For instance, at the end of the script when PHP needs to
save the current session variables, it'll call your "write()" function. You
just use sessions as normal, though.

[PHP] security and extended ascii characters

[Chris W]

In an effort to make sure no binary data is maliciously submitted via a
form I have code the makes sure all characters in any input field are
with in the range of a space to a "~".  However now that I am getting
some users of my site from Europe, that are having problems submitting
some extended characters.  I don't have the time to localize this site
for every language but I would like to make it so European users can
enter the character that you don't find in the English alphabet.  So I
was wondering what other ascii values I need to allow so users in Europe
won't have these problems?

[PHP] mysql went away

[Bill Green]

HI. I've been using mySQL 4.0.13, php4.3.4, and phpMyAdmin2.5.5 on Mac 
OS 10.3.3 as a learning/testing/development environment for a couple of 
months now - no problems, works great.

I've created more than a few mySQL databases and tables, but yesterday 
I created a database, a table, and LOAD DATA from within phpMyAdmin. 
Successfully. I looked at the data and all was fine. Logged out and 
went away for a while. Came back and phpMyAdmin would not show me my 
databases in the left frame, and I could not launch a query window. I 
could see runtime information, system vars, processes, and even 
privileges.

I tried logging in to mySQL through the terminal Through the command 
line client I can run simple commands, but no commands to view or 
affect databases or tables.

I can run php scripts from a browser - connect to databases, retrieve 
and even insert/update data, but I cannot view databases or tables, and 
though I haven't tried I doubt I'll be able to create, delete, or 
backup databases or tables.

Does anyone have a clue about what the problems may be or where I 
should start?

Isn't this potentially a DoS attack vector anyway? I don't need a server
to accept or read my obscenely long POST requests to clog the pipes with
them. Would the proper way to handle this risk be to disallow POST at the
webserver level, or does turning always_populate_raw_post_data off cause
the connection to be automatically dropped after Connection: close?

If it was always enabled, it sure would make a DoS attack easy. I'd just
send lots of huge POST requests to any PHP script on your server. Hope you

[PHP] mcrypt & pdflib configuration

[William Holroyd]

I've already posted this question in comp.lang.php but no one seemed to have
an answer to it.

So I've got PHP to recognize mcrypt and pdflib in the phpinfo() output, but
trying to use any of the functions fail with "...undefined function
called..". There aren't any configurable files with either distro and
neither mention php.ini settings need to be made. Restarting the apache
server does not fix this and no errors are reported while starting.

The most recent stable releases Apache 2.0.49 and PHP 4.3.6 are being used
with mcrypt 2.4 (stable, but 2.6.4 is most recent) and pdflib 5.0.3p1 (most
recent stable release) libraries, running on Windows 2003 Server Enterprise
with all updates applied.

I picked up a copy of Visual Studio .NET Enterprise but am also stumped of
how to compile these functions from source which I would prefer to do at
this point.

Any help on either topic is much appreciated.

Using the absolute path works as well - but you have to use the full LOCAL
file path, e.g. /htdocs/www/your-domain etc.

You can get this value from $_SERVER['DOCUMENT_ROOT'].

[PHP] SuExec and PHP

[Travis Low]

Greetings.  We have a need for our PHP scripts to run as the user and group 
associated with each Apache virtual domain on our Redhat server.  Currently, 
all PHP scripts run as nobody.nobody.

I know that the apache suexec module allows CGI scripts to run as the user and 
group of the virtual host, but that doesn't seem to be the case for PHP scripts 
run under the apache php module (mod_php).

So my questions are:

(1) Can we use suexec to force PHP scripts (running under mod_php) to run as 
the user/group associated with the virtual host?  If so, how?  Are there any 
special configuration tricks to make this happen?

(2) If we CAN'T use suexec with mod_php, I assume we can run PHP as CGI to 
solve our problem.  However, I'm worried about performance.  Have any of you 
done this on linux?  Is it difficult to configure?  Do you have to audit all of 
your PHP scripts?  Etc., etc.

I did read the pages http://www.php.net/security.cgi_bin and 
http://www.php.net/manual/en/security.apache.php, but did not come away with 
clear answers to my questions.  There were also a lot of contradictory comments 
at the bottom of those pages, and a whole mess of stuff on google, so I'm 
getting more lost, not less.  Please help!

cheers,

Travis

[PHP] Using PHP4 4.3.4 as a CGI

[Mark Constable]

Debian testing system with a recent update to php-cgi 4.3.4.

I have been using the /usr/bin/php4 binary as a some.cgi with
a shbang line of "#!/usr/bin/php4" which worked fine up until
this recent 4.3.4 update. Now the new 4.3.4 php4 binary does
not produce a "Content-type: index/html\n\n" header nor does
it receive any GPC (GET POST etc) variables at all. I've been
throught the new php.ini and I cannot see any parameters or
advice as to what may have changed.

Could anyone advise me how to re-enable receiving incoming
variables for a /usr/bin/php4 binary used as a CGI please ?

Remove the line adding 'Any' at the beginning of your code and use

do you really need to maintain the numeric keys to the array by using
asort() instead of just sort()? If so, this may not work. You may be able to
use array_splice($input, 0, 0, array('Any')) or array_merge().

No, it's not a web form.  I'm trying to include an IP addressed video camera
into my webpage.  The problem is that the video camera is password protected
using htaccess.  I don't have the option to remove the password.

I tried looking through the PEAR auth libraries but I didn't find anything
that *passed* authentication info, but only prompted for it, etc.

I thought there would be a class that would allow me to send the username
and password to a website and then include it, something like the following
pseudo-code:

website_address("http://127.0.0.1";);
$crap->website_username("joe");
$crap->website_password("shmoe");
$crap->retune_website();


?>

The camera used to be accessible with:

http://joe:[EMAIL PROTECTED]

But it is no longer available via Internet Explorer since the new MS
security updates on most windows boxes.

Thanks again.

Constants are more for the programmer to use within the program to
avoid hard coding arbitrary numbers embeded deep inside code.

You can use a combination of both Constants and arrays to achive
your task:

define('SEND_DS', 1);
define('SEND_DS_ACK', 2);
...

$lookup = array(
  SEND_DS  => 'SEND_DS',
  SEND_DS_ACK  => 'SEND_DS_ACK',
);

Well, it comes through as an image map in most browsers. I've found that 
you can't rely on the value of a submit button anyway as it is usually 
possible to just hit enter in a form to submit it, which, in most 
browsers, doesn't send the submit button. Use a hidden or ohter field to 
check for submission.

mozilla/firefox is the only browser that I know of that will pass

nothing. i usually don't give my image buttons a name value so that
never shows up. what it's meant for is server side image maps. the
browser is telling the server where on the image the user clicked. then
you as the programmer decide where the user be taken depending on where
they clicked.

[PHP] Constant questions

[René Fournier]

Hi,

I have two questions involving Constants.

1. I want to refer to a refer to a Constant by its value (which is 
unique), and return its name. E.g.,:

define ("SEND_DS","1");
define ("SEND_DS_ACK","2");
define ("RESEND_DS","3");
define ("STARTUP_DS","12");
For example, if I receive "3", I would like to echo "RESEND_DS"--the 
name of the constant. Is there a simply way to do this? Or am I better 
using an Associative Array (which is what I was thinking)? Then I could 
such refer to an element by its key or value (both of which are 
unique). I suppose this more of a performance/elegance issue, than 
outright problem. Just curious what you think.

2. Let's say I have a Constant called MY_NAME, the value of which is 
"Rene", and I pass it to a function, such as:

function example ($val) {
echo ???;
}
example (MY_NAME);

Such that the output will be MY_NAME. If I echo $val, the output will 
be Rene. But I want to see the constants Name, not Value. Any ideas?

Thanks.

There are quite a few some have already been mentioned, in other posts

Having said that you probably ought to switch to FTP or SFTP if you want

[PHP] changing http to https

[David T-G]

Hi, all --

We have lovely variables like $_SERVER['SCRIPT_URI'] so that we don't
have to hard-code the site or script name into our files, and that's
great; it even includes the SID for me if cookies are off.  I'd like to
be able to point someone to https://sitename/script.php to log in
securely, but I see no way of changing the request method or port number
or such.  So far all I've dreamed up is to either manually build

  https://{$_SERVER['HTTP_HOST']}{$_SERVER['SCRIPT_NAME']}

or perhaps

  str_replace('http','https',$_SERVER['SCRIPT_URI'])

which both seem kinda kludgey.

Any better ideas?

[PHP] function "gethostbyname" - how can i deactivate cache / force look-up???

[Tobes]

Hi there -
in a script I use the function "gethostbyname" to resolve a hostname
(www.example.com) into an IP-address.
Unfortunately, the host name that I try to resolve changes its IP address
frequently.
Since the function "gethostbyname" caches its results, it sooner or later
returns a wrong IP-address.

How can I deactivate cache for this function (or force the look-up) or what
other function could I use to get the IP-address?

Thanks a lot for your help in advance!!!

[PHP] Linux command in PHP

[Mike Mapsnac]

I have script  that basically process a file. If  something found in the 
file, the script send email.

Today I tried to add another  option, that gives sound and send email.
The script works ok when I run from  shell. But when I add the code to 
cronjob, the email is send but NO SOUND. Any ideas what can cause such 
problem?

# Below the code that start the xmms sound
$alert = "/usr/bin/xmms /home/mike/Desktop/song1.mp3";
`$alert';

Include an Authorization header, which should look something like this:

Authorization: Basic bXluYW1lOm15cGFzcw==

The encoded string is just the result of this:

base64_encode('myname:mypass')

Substitute with the correct username and password.

Hope that helps.

[PHP] FIXED: Max file size for uploads?

[Robert Sossomon]

It's fixed now..

If using Apache on RedHat here is everything to fix at once:

FIRST AND FOREMOST DECIDE THE MAX SIZE YOU WANT IN MB, ADD A COUPLE MORE
TO IT, AND THEN CONVERT TO BYTES (MB * 1024 * 1024)

1.  httpd/conf.d/php.conf 
LimitRequestBody  ?? #byte size you calculated

2.  /etc/php.ini
max_file_size = ???M #Max size in MB
post_max_size = ???M #Max size in MB

/etc/init.d/httpd restart

Then upload!  

HTH!!

This still looks like PHP is not looking for the php.ini file where you
think it is.  I strongly suggest you follow the previous advice to work out
where PHP is actually expecting your php.ini to be, before you have a need
to change another initialization parameter.

Cheers!

What version of php are you using? It appears to work with RC1 to
CVS version. The actual result I get is:

public function Debug() {

  echo self::$myInstance;   // works
  echo parent::$myInstance; // error: Cannot access protected property
  echo A::$myInstance;  // error: Cannot access protected property
}

Its expected for the errors on the last two since you're accessing
the protected variable from outsite the public scope of Debug().

Another option, if you wish to have varying argument lists, is to define
the methods with no arguments at all, and use the func_get_args(),
func_num_args(), and func_get_arg() functions described here:

Anyone have any clue why this is the case? Is there a performance reason
that raw post data must be explicitly enabled, or is it more of a
protective measure for overly permissive beginner scripts?

Re: [PHP] Sessions not working on Linux - Apache - FOllow Up

[Zac]

Have looked at this more and can now tell you that this is definatley 
down to the server not writing any contents into the sess_nnn file.

Does anyone have any ideas why this would happen? I've checked all 
permissions and tried changing the save_path to another folder that I 
created specifically for the sessions with global write permissions this 
had no effect.

Made sure the $_SESSION[name] had '  - $_SESSION['name'] made no 
difference. (Thanks though)

Any help really appreciated.

Zac


Running on apache 1.3

session.save_handler = files
session.save_path = /tmp
session.use_cookies = 1
session.name = i
session.auto_start = 0
session.cookie_lifetime = 0
session_start() is included in the top of each page.

When I test session files are being written into the /tmp folder and the 
session variable is corerctly added to the url when moving to another 
page, BUT the sessions do not appear to be working?

I can set a session var on one page and display it there but when moving 
to another page the session var is no longer available?

If I look in the tmp folder a relevant sess_nnn file is there but 
contains no data. I've checked permissions and the /tmp folder is world 
writable and the sess_nnn file is owned by the web server and is writable?

Can anyone suggest what to test next or where the problem may be?

Thanks

Zac

If you assign default values to the method arguments, you cannot test
them with isset() anymore, as they will be set.

Re: [PHP] default and another constructor

[Rudy Metzger]

Strange that you get this error. Normally you should get a "Fatal error:
Cannot redeclare forum::forum() "

PHP does not support 'function overloading', at least not in a way java
is doing it. One of the drawbacks of a free typed langauge (in contrary
to a strictly typed one).

No, you cannot do this kind of method overloading, not like 
this anyway. If you are using PHP5 you can kind of emulate 
overloading by using the __call() function... some googling 
will find examples.

You can at least make the below work by removing the first
forum() instance and using

 function forum($naam=NULL,$tijd=NULL,$tekst=NULL)

and test the incoming variables with isset() before attempting
to use any of them.

No worries. One point though - make sure you use $_GET['name'] and
*not* $_GET[name] (note the lack of quotes) - there is a big
difference between the two, the un-quoted version will cause PHP to
check its defined constants first, so you're adding un-needed overhead
and potential error warnings just by missing out those two little
characters :)

[PHP] Re: PHP5 and static attributes

[Aidan Lister]

Do you have to access that variable statically?

If you're scope is the class:
echo $this->myInstance;

Otherwise,
echo C::$myInstance will access it outside the class (I think), even though
it's inherited.
