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

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'].

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.

Hi,
I have this code (below) that waits for particular data to come over
the socket ("ENX"), at which point it breaks out of the loop and does
other things. Presently, it will loop forever, until it receives
"ENX"—a good start—but I also need it to break-out if the loop runs
longer than five seconds. This is where I'm having a problem. It seems
that it is only reading once data comes over the socket, so it is stuck
on that first 'while' line ("while(($buf =
socket_read($socket,128,PHP_BINARY_READ)) !== false) {").
$timer = time();
while(($buf = socket_read($socket,128,PHP_BINARY_READ)) !== false) {
$data .= $buf;
$elapsed = time() - $timer;
if(preg_match("/ENX/", $data)) {
break;
} elseif ($elapsed > 5) {
echo "TOO LONG!\n";
break;
}
}
Maybe set non-blocking / blocking socket is the answer? Only problem is
I can't find much [good] documentation describing what blocking and
non-blocking sockets are good for, etc. Any ideas? Thanks.

blocking - wait for response or till timeout
non-blocking - return right away
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
while(($buf = socket_read($socket,128,PHP_BINARY_READ)) !== false) {
//...
}
if ($error = socket_last_error($socket) ) {
echo "socket error [$error]:" . socket_strerror($error);
}
or something like that.

Thanks for the help, but.... I now get the error "PHP Warning:

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 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
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?

This is what our tangential conversation touched on. Curt mentioned that
always_populate_raw_post_data is a funny name, and I mentioned how it was
also misleading (always should mean always).
I assume the original poster is using neither of the content types you
mention, since this was already working for him in one environment.

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.

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! :)

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?

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?

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?

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.

Works as advertised. Made it a sort.

I do the following:
$eventList = array();
$eventList[] = "Any";
$dbh = db_open($host, $user, $password, $database);
if($dbh) {
$sthdl = db_get_event_data($dbh);
while ($row = mysql_fetch_object($sthdl)) {
$eventList[] = $row->EV_EVENT;
}
} else {
$eventList[] = "* None found *";
}
asort( $eventList );
Now I want to put "Any" as the first item. What is the best way to do
this? Often the sort puts it as an item down the list.
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);
while ($row = mysql_fetch_object($sthdl)) {
$eventList[] = $row->EV_EVENT;
}
} else {
$eventList[] = "* None found *";
}
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().

it are different table and the first table does not contain names, onlu the
id form names.
Ordering ASC woll not work because it is not in the first query

Hi all,
Can anyone point me in the direction of a site search engine that reads
files in a directory find relevant results for an search term that a
person might enter on a site?
I need to build a site search engine but the problem is. the site isn't
dynamic (yet) so I need to read actual files to pull things together.
Anything out there?
Thanks!
Aaron

Hey Guys,
Question 1: Does anyone have a really good php form validation script
for Zip-codes?
Question 2: Does anyone know of a great depository of form validation
scripts for all kinds of form inputs?
Question 3: Does anyone know (yea I know, getting tedious here) of a
way or program to check the real distance from one zip-code to another
zip-code like on yahoo maps?
Thank you.
Later,
Ryan

hey...
hi. we're looking for a good/really good web based user directory
application. we'd like the app to be able to allow users to login, and add
information to their profile. we'd prefer an app that would provide the
ability to select/add additional information fields and not constrain us. we
would also like an app that allows the user to upload a picture for the
other users to be able to see...
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"...
Thanks,
bruce

Of course...why pay for something so useful??
Maybe you would also prefer for someone to make this for you...open source
and free of course :-)

we've seen apps that have had some of the functions we're looking for... ie
dating apps, cms systems, etc... we're curious if anybody has seen/used
something that they've considered to be really good/solid...

I have been playing with PHP5 and am liking it more and more. But I have one
question about "instanceof"
If you have something like this:
<?
class A { }
class B extends A { }
$x = new B;
if ($x instanceof B) echo "B";
if ($x instanceof A) echo "A";
?>
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?
Thanks
Martin

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

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!

ah yes, of course "instanceof" means you're working with an instance of an
class - <slaps forehead>
Pity there's no equivalent for classes :( oh well, I'll just have
instantiate the class first then do the checking.
Thanks

I need to email linked files (URLs are retrieved from a database) with PHP

Could one of you help me in saving the remote file to the local webserver?
