all dirs in that path are readable by everyone (read and execute flag set),
the executable is also readable & executable by everyone.

that is correct right?

Yeh, dirs should be 755, the file should be at least 755.

What o/s is this? If it's fedora 4+ do you have seLinux enabled or
something? I wonder if something else is getting in the way..

Does *any* php script give same error?
Even the simplest one like:
-- sample --
#!/path/to/php -q
<?
echo "something!!";
?>
-- end sample --

Do you have root access on this machine? Perhaps the sysadmin as
configured bash to not accept "unknown" interpreters? I'd image that
this is fairly easy to do, tho' not looked into it before.

You could also try:

#!/usr/bin/env php

instead and see if that works.

If the FS permissions to the binary are correct, odds are the file system is
actually mounted noexec.

There are only 2 other possibilities I can think of...

1) PHP CLI is not installed correctly
2) The mount you are executing it on is mounted noexec

Thanks for the answers.

I will launch anyway this solution, it is more secure for us... I will
monitor the server to see if it can handle the load.

I'd recomend doing a bit of benchmarking to figure out if the
performance hit is acceptable. Using php is the easiest solution.

Assuming that PHP is too slow for you, you can actually solve this issue
with some abuse of mod_rewrite.

You can use cookies to control the access by using the cookie variable
with mod_rewrite, it's accessible as HTTP_COOKIE. You will need to
parse the cookie string yourself.
This allows you to do something like link to user.png and set a cookie
user=35 and have mod_rewrite change it to access the 35.png file. You
can also do things like block anything that doesn't match 35.....png.
You can't do anything fancy like DB based permissions though.

Using cookies is still not secure however. You can obstuficate it
fairly well but a determined user can still get around any cookie
protections. You can beef up the mod_rewrite to handle this by using an
external program via RewriteMap and php session files, even database
access is possible. However 99% of the time I don't think that it would
be worth it.

Yes.

How much of a difference it makes depends on YOUR hardware.

Test it and see is the only sensible answer we can give.

This is probably a good starting point:

Hi all!

I'm trying to learn using PDO and PostgreSQL together a little bit and I
have some problems with (I thinks, auto incrementing fields)
I have the following sample DB:

CREATE TABLE users (
uid SERIAL UNIQUE NOT NULL,
login TEXT NOT NULL,
password TEXT NOT NULL,
PRIMARY KEY (uid)
);

and the following PHP code:

<?php
try {
   $db = new PDO('pgsql:host=localhost;dbname=testing', 'XXXX', 'ZZZZZ');
   $db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
 
   $query = "INSERT INTO users SET uid = :uid, login = :login, password
= :password";
   $stmt = $db->prepare($query);

   $uid = "";
   $login = "erik";
   $password = "erikSecretPass";
  
   $stmt->bindParam(':uid', $uid);
   $stmt->bindParam(':login', $login);
   $stmt->bindParam(':password', $password);
  
   $stmt->execute();
  
   $db = null;
} catch (PDOException $e) {
   print "Error!: " . $e->getMessage() . "<br/>";
   die();
}
?>

When running the script I get the following error message: Error!:
SQLSTATE[42601]: Syntax error: 7 ERROR: syntax error at or near "SET" at
character 19

I know that I doing something bad, maybe with the udi column, how to use
auto incrementing columns with PDO?

Thanks very much for your time.

The INSERT INTO ... SET ... syntax is not standard SQL. It's a mysql
extension that isn't supported by any other sql databases, such as
postgresql.

The proper insert syntax is here:

Well it seems like u made a mess there with arrays...

<?
 $first[] = array('appple', 'pear', 'banana');
 $second = serialize($first);
 $third[]= unserialize($second);

 echo $second; //outputs serialized data
 echo $third[1];

?>

From definition of first I understand it's an array of arrays with
element on position 0 (ZERO) set to an array of apple, pear, banana
elements.
If u serialize it and unserialize it you will obtain same thing...

so at the end of the script you should

echo $third[0];

I think you misunderstand how arrays work (at least in your example)

I think you really meant to try something like this:

<?
$first = array('appple', 'pear', 'banana');
$second = serialize($first);
$third= unserialize($second);

// $first == $third;

var_dump($first);

var_dump($third);

echo $first[1]; // pear
echo $third[1]; // pear

Some spam filters mark poorly formed HTML as SPAM, so make sure that
your message complies to the HTML standards. e.g. Just a table without a
body and opening html tags is probably invalid HTML...

Just a thought.

Well, html e-mail is generally a Bad Thing. Many people (myself
included) use applications such as SpamAssassin and html in e-mail
increases it's 'spamminess' from a scoring point of view.

PHP list,

I have many times set the value of a variable by declaring it in the
URL, like so:

http://www.domain.com/index.php?var=1

And then, to use the variable, all I have to do is use it in the script,
like so:

echo "This is the value of the variable: " . $var;

But, for some reason, in a script I'm writing now, this simple process
isn't working.

The only thing I can think of that is different between before and now
is that the new script is being executed in PHP5, whereas before was
with PHP4.

In my new script, I check the value of $_SERVER['QUERY_STRING'], the
value is contained in there, so it is being assigned and contained somehow.

What could I possibly be missing in what should be a super simple process?

To expand on Jay's excellent advice, you have been depending on "register
globals" to set the variable names for you. This is widely regarded as a
bad practice, because you don't know for sure where $var came from. You
should ALWAYS use $var=$_GET['var'] when taking values from the url to set a
variable.

For more information on the evils of register globals, STFA. There have
been many discussions in this list on that topic.

Before, you were relying on PHP's register_globals setting, which did
what you describe. Since the use of this setting is an enormous security
hole, and there is zero reason to use it outside of backwards
compatibility with old scripts, it has long since been disabled by default.

You should instead reference GET variables like so:

$_GET['var']

And POST like this:

$_POST['var']

This is much safer. If you REALLY want to turn on register_globals (And
I strongly recommend against it, it's a huge risk), information on how
to do this can be found in the PHP manual.

 Yes it is.

 $_FILES['{form_field_name}']['type'] is your friend here. Just match it
against a mime type your looking for.

If you have a suitible mime.magic file, and your PHP has the
functionality built into it, you could try the mime_content_type() function.
http://uk.php.net/manual/en/function.mime-content-type.php

Or if not available, read the first few bytes of the file and verify
that it begins with:
%PDF-1.3
(or other versions - perhaps just verify the first 4 chars.

You can do this with a simple

$fp = fopen($filename, 'rb'));
if ('%PDF' == fread($fp, 4))
   // PDF
else
   // Not PDF

This is very simple.

You could also use the "file" commandline utility if the server is a
*nix machine and parse it's output.

e.g. on my machine:
[colinjimmy www]$ file ~/Desktop/svn-book.pdf
/home/colin/Desktop/svn-book.pdf: PDF document, version 1.3

or easier:

[colinjimmy www]$ file -i ~/Desktop/svn-book.pdf
/home/colin/Desktop/svn-book.pdf: application/pdf

Is this to protect against somebody trying to pass an mp3 off as a PDF, or
to stop people mistakenly uploading PDF's. If it's the latter, then mime
functions are probably okay. If the former, then you may want something a
little more through.

And very insecure. All it takes is a cat and echo to disguise a file as a
PDF, and a quick 'dd skip' to Undisguise it.

Absolutely! Incredibly insecure! :)

But again as you stated yourself, if it's just to help users rather than
preventing unotherised content, then either way would work most of the
time. It would be fairly trivial to write a valid PDF that was actually
an MP3 encoded specially, a few pages or so of base64 would do!!

There are probably some whitespaces in the elements which refuse to be
deleted.
Also consider using array_filter() instead of looping through the array
(used without a callback function filter all elements which evaluate to
boolean false).

Your Connection header is redundant, since that's the default value in
HTTP/1.1.

I would send the header but give it a value of close, since I see no
good reason to leave the TCP connection open until it times out. That's
a pretty big waste in a situation where overhead matters.

Hope that helps.

I missed the context of this function, but it seems like you probably

The context is a bit strange, these POST transactions are being used to
send data packets, since it's really the only way to send data to a
server-side PHP script. The scripts involved are used to tunnel
arbitrary TCP/IP data over a standard HTTP connection. The keepalive
means that many POST transactions can be done in one connection, saving
the latency and overhead involved in establishing new TCP/IP
connections. And the content type of an octet stream is used because
x-www-form-urlencoded would have to be decoded by the script on the
server side. With an octet stream, the server-side script can just read
the data in from php://input.

Thanks for the hint on the Connection header. It'll save me from more
overhead :)

Before you try to access the $_SESSION['results'] array, do this...

if (!isset($_SESSION['results'])) $_SESSION['results'] = array();

As far as counting and outputting a session array there is nothing
special about them - they are the same as any other array variable. This
means you can use foreach, print_r, var_dump, etc on them.

always call session_start() before using $_SESSION

I am creating an array of sessions

$_SESSION['results'][]

There may be up to 7 and I need to know why do I always get the
notice'Undefined index: results in...'?

How do I define or initialise the array if it only gets set once the form
has been posted (an answer has been given) on the page.

Is there a way to count/output (FOR EACH?) a set of session arrays like
this?

Ok,

I am using a hosted server and php is installed from the linux distro. I
usually have all the stuff in a php file somewhere so I can just go back
./configure, etc. I can't seem to find the configure for php on this box so
I can recompile but I know it is there as I can use php and see the version,
how can I find the configure to use?

Thanks!

php -l | grep configure

or

<? phpinfo();

Ok, doing that now and it's taking a while. I can do phpinfo but that tells
me the config line and where the ini files are, not necessarily where the
configure stuff is to recompile...correct?

it might take forever. I made a thinko, it should have been:

php -i | grep configure

(it should be pretty much instantaneous)

I can do phpinfo but that

correct, other than the system libs (which you refer to for some configure options)
- I doubt those would have change.

which pretty much leaves the php sources - and this you can download from
lots of places (you don't need to recompile from the same directory), if php
was installed as a package you will not have the source locally (probably) and
the chances are you'll be missing a stack of libs and/or development header files
which you would then need to install (again this depends on what configure flag
you're going to use)

You will only need JavaScript.

Remember, JavaScript is client-side, PHP is server-side.

You have 150 posts since February 5th 2005, are you pulling our leg? or
are you missing a few neurons?

Cheers,
Rob.

PHP is executed on the server, so you cannot campute something without
sending it back, reprocessing the form and put the result on the client
browser's. Some basic tasks can be done in the client with javascript,
but you have no much choices to accomplish what you want:
1)Ajax (change or reload a section or node of your document based on an
action)
2)Frames and Javascript (reload only a frame with javascript, for example)

There are many good examples out there of either ways.

Regards,

Mariano.

PHP is a server-side language. Javascript is a client-side language.
Such things need to be done on the client side, at which point they're
usually called AJAX. PHP can be used for the server-side of an AJAX
application.

I've touched on them. Though I'm sure we both know to which kind of
neuron I was referring :)
