Why is it that when you forget a "}" the error says:

Why can't it just say:
Missing } on or before (best guess).
How could the parser possibly know that one was missing as it's going
through the file? It just keeps a count and can only realize something
is wrong when it gets to the end of the file and sees the count is off.

I can't see how a human could determine this prior to getting to the end
either, unless you assume that the author has properly indented the code. Am I
missing something obvious?
if ($foo) { if ($bar) echo 'blah'; else { echo 'else'; }
Where is the missing brace? :-)

I'm pretty sure I've seen an error message from something (maybe,
asp.net, or classic asp) that shows a line like i've drawn and points to
where it thinks the problem is. (And no it wasn't always the end of the
last line.) But maybe my memory is a little foggy.

I should also add (before someone corrects me) that is could have been
related to syntax errors only and not missing braces. Thus the "But
maybe my memory is a little foggy." clause in my previous post.

I think Curt got my point the best. :-)
The point is that you can't tell where I forgot the brace without making
assumptions about what I wanted to do. If a human can't tell whether there is a
missing brace until the very end, a human can't write software that does
either.

Please read my previous posts again.
FWIW, I had to go through the trouble of locating the jpeg libraries and
downloading http://www.ijg.org/files/jpegsrc.v6b.tar.gz and extracting it and
reading the installation instructions to enable me to write what I wrote in
my previous posts. The least you could do is read it!

Hey,
I am setting up Apache 1.3.27 on a linux box (I really dont know much about
linux) and I am having small problem. When a specify a subdirectory off of
my document root, I must include a "/" forward slash in order for the index
page to load, otherwise I get the "The page cannot be displayed" message.
For example, I must type:
http://somedomain/phpmyadmin/
instead of
http://somedomain/phpmyadmin
My only previous experience with configuring apache is on Win machines,
where I haven't had this problem before. I know this is off topic but u guys
know everything, so any help would be greatly appreciated. Thanks

Hi there,
I would like to create a small dev log.
Output should be somehow like this:
Aug 30, 2003
1. Member galleries added sort option rating
Aug 31, 2003
1. Travel log entries can be dated now.
2. Member galleries added 5 star rating system
NOw I have created a table with 2 rows (timestamp and entry)
I would like to pull out the date aout of the db, group it by date and
output all entries for this date in a listformat, then proceed to the
next date.
Unfortuantelley this looks way more complicated than I thought. How to
group by date and still get the entry, and how can I arange it, that it
outputs only the one for the date and then closes the list`?
Thanx for any help on that,
Merlin

To display the output like you've got in your post you'd do something
like this:
(pseudo code)
$arrayOfEntries = GetEntries();
$previousDate = "";
foreach($arrayOfEntries as $entry)
{
if($previousDate != $entry['date'])
{
// show date header
// show comment for this record
}
else
{
// show comment only
}
$previousDate = $entry['date'];
}
Let me know if this helps (and if it doesn't too).
Chris.
--- End Message ---
--- Begin Message ---
Thanx Chris, this works. Here is the code (might help somebody else)
unset($previousDate);
for ($i=0; $i < $num_results; $i++){
if($previousDate != $log['date'][$i])
echo '<b>'.$log[date][$i].'</b>'.$p.'<ul>';
echo '<li>'.$log[entry][$i].'</li>';
$previousDate = $log['date'][$i];
if($previousDate != $log['date'][$i+1]){
echo '</ul>';
}
}

I'm currently working on a portion of a website for my high school's
band (though I'm now in college) and one of the sections contains
contact information for all of the students which should only be
accessible if you have are a member of band staff and have a password.
In order to access the "band staff" section, you are required to enter
in a username and password and from there you can visit any of the
pages in the band staff section. So it's fairly straight forward, login
view the pages, type of system.
My question is, how should I go about determining whether the user has
logged in or not? Are sessions overkill or difficult to use? Or is
there another easier solution? This doesn't have to be maximum security
or handle a variety of approaches to the pages, I'm just looking for a
simple, "unless you're logged in, you can't see this page."
Are sessions the way to go?

Well you could use cookies also but those can be tampered with.
Sessions aren't hard to work with really. All you need to do is start
the session, write a variable to $_SESSION if they have authenticated
successfully and then check for the existence of that variable on every
page. If it doesn't exist they have not authenticated.
Those are the basics.
Chris.

Honestly if you have the users logging in use a session variable to contain
a session id
then verify against that sessionid as they browse the sensitive sections and
use a class to verify that they are a valid user
so yes Ideally sessions are the way to go

Hey maybe you guys can help me out here.
I would like to start developing for WAP enabled devices. since there
are a lot of people out there who still have phones that use different
version of WML and still some that use HDML. and then the new phones
being able to display XHTML. I would like to either find a parser or
make one that will convert a XHTML file to be compatable with the older
mark-up languages. does anyone have experience with this?
Give you an example.. I have a Sanyo SCP-4700 on the Sprint PCS network.
only HDML 3.0 and WML 1.1 is compatable.. So I run into a lot of
different errors.
So the first step would be to figure out how to determine a cell phone
user's browser. So what's it capable of WML 1.1 or WML 2.0, HDML.. Or
XHTML
Appreciate the feedback,

Hi,
The best approach for you is to use XSLT. good information about XSLT
can be found on w3shcools.com
briefly what it can do is to take an xml and convert it to virtually any
other format. For this is to happen though you need to have strict XHTML
transistion will not do because it's not always well formed.
If you are really keen to parse your XHTML and go on that path, it can
be done with SAX (once again provided that it's well formed). Otherwise
the best HTML parser i have seen actuall comes with perl.
best regards
raditha

Hi,
I'm looking for good and complete documentation about hardening a PHP
box which is going to be used to offer hosting services. The machine
will have Apache + PHP with VirtualDomains. Assuming Apache config is
secure, which aspects would be affected for the activation of php
module?
I'd like a have a look to a complete php.ini checklist. I've been
doing some basic research and I found useful some tips:
- safe_mode on (solves remote execution of arbitrary code)
- open_basedir "./" (solves browsing HD' server problem)
- some limits like memory or CPU time used by a given php script
- disable fsockopen and pfsockopen (solves the problem in launching a
connect to remote hosts from the PHP/web server).
Regarding last point, is there any php.ini option to disable ALL (at
the same time) PHP dangerous network commands such as fsockopen?
Any more clues?
Any help would be greatly appreciated. Thanks in advance.
Saludos,

Use php over cgi and try a sbox/suexec wrapper to create a secure
environment.

Safe_mode on makes a http fileupload for users impossible when using php as
a module. So the most php based apps like gallerys, cms cant run at your
environment.

Use a firewall or something like iptables to makes outgoing connections
forbidden. Use ulimits or other job restriction to set runtime limits for
the cgi processes.

Learn more about your given webserver. Alls these problems are not generated
by php. You'll have the same problems when runing perl,python as a module
becaue all these runing under the rights of the webserver user.

You can psudo trap the error message, if you have the php.ini
setting 'track_errors' on then you can do something like:
if (! @imap_fetchstructure(...) ) {
array_push($errors, $php_errormsg);
}
The @ suppresses direct output to the browser. and php_errormsg
contains the string that woulda been sent.

I'm logging in via a form, and on the form page it creates the session:
<?php
session_start();
if ($_POST['username'] == $username && $_POST['password'] == $password
) {
$_SESSION['loggedIn'] = true;
} else
$_SESSION['loggedIn'] = false;
?>
And later in the same page, I include another file which has the links
to the pages within the secured section of the site:
<?php if ($_SESSION['loggedIn']) require("section_nav.php"); ?>
From there, when I go to another page, that same line of doesn't work,
as the links are not shown. Any idea on why that's happening? Did I
miss a step?

Does the next page call session_start()? all pages that use
$_SESSION, must call that first.

You could equally ask why we get plagued with silly strap lines like

No, you can't *equally* ask why. It is perfectly acceptable to
have a signature attached to your email. It is not acceptable to
have a 15 line message wrapped in a box describing the company's
privacy disclaimer.
oh, and it is hardly a strapline, or well.. mabey not :)

After upgrading from php 4.0.x to 4.2.3
many previous php scripts that had been working failed
becos of the "include" statement
The apache error log logged "segmentation fault"
I think it might have to do with AIX as there are
no problems for 4.2.3 which I've installed on Tru 64 Unix
(I've checked the php.ini file and the are the same on both platforms)
Anyone who has encountered this for AIX ?

It seems that HTML is LAME, LAME,LAME when it comes to determining local
directories.
I would like to somehow:
put image links relative to a base directory (if a relative URI is
given)
and have PAGE links relative to the current page (if a relative URI
is given)
What I seem to be able to do instead, is to:
with NO <base href="websitehost/~my_directory/"> in the header
hard code the location of the images
use relative URI for pages
-OR-
with NO <base href="websitehost/~my_directory/"> in the header
use relative location of the images
hard code the URI for pages
there seems no way to tell the browser to look below the base of the
site for relative URI for images,
but do local to the current file relative for other pages.
And doing '"/someURI" makes the browser go off the site and not the base.
GRRRRR.
I can either get my images from a particular place on my site by
hardcoding the exact UR

This is a PHP list, not an HTML list. What does this have to do with PHP?

Never said they don't, but the HTML PHP outputs has nothing to do with
PHP. Take this to an HTML list/newsgroup.

From what I see, the default timeout for a session is 1440 seconds or
24 minutes. I was gone for nearly an hour, came back, and the session
was still valid. Must the value set in the config file be different
than 1440, or am I misunderstanding session.gc_maxlifetime? I'd like
for the user to be required to log in if they've been inactive for 10
minutes, or if they closed the browser window and opened another one.
Sorry for all the basic questions :)

The session timeout just sets the maximum time before the session data
becomes valid for a garbage collect. If a garbage collect is not
triggered the data is still valid as far as php is concerned. You have
to implement your own timeout checks if you need exactly 24 minutes.
You can do this by storeing the last accessed time in the $_SESSION
array and check it on each start.
I think by default garbage is collected 1 in every 100 hits. (1%)
If it done on every hit it would start to impact performance on busy
sites.

The issue with the session still being around when your browser
closed then reopened has to with the ini setting:
session.cookie_lifetime
You want it to be 0, for it to expire as soon as the browser closes.
You might want to manage your lifetime of the session yourself,
like Tom Rogers suggested. This will also avoid issues with clock
settings on the client's computer. So a set up with something like
this:
php.ini:
session.cookie_lifetime = 0
file.php:
$lifetime = (60 * 10); // 10 minutes lifetime
session_start();
if (! empty($_SESSION['last_access'] &&
$_SESSION['last_access'] >= (time() + $lifetime) ) {
// Session has expired
$_SESSION = array(); // kill session
} else {
$_SESSION['last_access'] = time();
}
-OR-
if you're not worried about the client's clock being fast or slow:
php.ini:
session.cookie_lifetime = 10;

Hi,
I have some questions. Is it possible to pass login data such
as username and password to the HTTP Basic Authentication
dialog box from PHP? How do you code that?
Is it also possible to get the variable data from the Authentication
dialog once login? I tried putting phpinfo() in an index.php page inside
the web protected directory but I can only see the username in the
variables..

I know for sure with Basic authentication you can't.
