--- Begin Message --- Hi all,

I need to convert some text from a database for presentation on screen... as per usual, characters like quotes and ampersands (&) are giving me grief. the obvious answer is to apply htmlspecialchars(), BUT this also converts all < and > into < and > signs, which destroys the html mark-up within the text.

Is there a non-tag equivalent of htmlspecialchars(), or do I need to build one?
TIA

You'll have to build one.

If you know what characters are causing trouble, you could just use str_replace on them. Or you could use htmlspecialchars() and then run str_replace to convert < and > back into brackets.

You could also use get_html_translation_table() to get the conversions, remove the < and > conversion elements of the array and then use strtr() to do the conversion.

Which is what I just did as a 'patch' :)

I like that idea a LOT.

--- Begin Message --- Looks like that code depends on register globals being enabled which have been off for some time. You can either turn register globals on in php.ini (not recommended) or with an .htaccess file (better than using php.ini not as good as changing the code if that is possible).

Information about all three of these is available at http://www.php.net/manual/en

If you own the code you can use $_SERVER['REQUEST_METHOD'].

Since I grabbed the code from a 2001 update, is there any chance that this is already obsolete? I checked the documentation but didn't find anything relevant. Any advice would be highly appreciated. ;-)

The following is the complete code that I got stuck at

if (($REQUEST_METHOD=='post')) {

And add appriopriate assigments at the top of your script.

No it's not a Dreamweaver problem....

I have a site where users can insert data via a PHP form, I want to be able
to set up a system where the user can login and edit their entries only, in
other words they cant edit another users data.

The php xml modules are installed by default with recent versions of php. This requires that you have libexpat on your machine. They are available on most linux distributions cds. If you are on windows you can dwonload from the site (forgotton the url)

From the type of questions you have asked i get the impression that youa re total newby to xml. Please head off the w3c.org you will find the specs there. You will find some good tutorials at w3schools.com

all the best

ps: The next time you ask a question you might want to start a new thread instead of replying to an exisiting message.

: SCRIPT_FILENAME, sorry but i didnt get this part.

On URL A, $_SERVER['SCRIPT_FILENAME'] reports URL A.  And on that page,
if you click on a link that takes you to URL B, then in URL B you'll get
$_SERVER['HTTP_REFERER'] that also says URL A.

Is anyone able to advise me on the security of the password when using

intercepted between the browser and server when submitted.

If you want this type of level security, you should work under SSL connection, that 
works with crypted data between browser and server.

Hello,

For my website I use some PHP code for navigation. Therefore I use a
directory structure which contains some navigation files the visitor can
open. The directory structure looks like this:

my_domain
     |
     - /navigation
     |              - file_1.html
     |              - file_2.html
     |              - file_3.html
     |
     -/images
     :
     :

The name of the files the visitor can open (file_1....file_3) I detect from
reading the files in the directory "navigation". The function I use is this:

$handle=opendir("./navigation/");
$counter=0;

while ($file = readdir($handle)) {

 $the_type = strrchr($file, ".");
 $is_html = eregi("htm",$the_type);
 if ($file != "." and $file != ".." and $is_html) {
   $newsflash[$counter] = $file;
   $counter++;

 }
}
closedir($handle);
rsort($newsflash);
reset($newsflash);

With some other code I can echo the different files, this code works on the
same server. Now I want to read the navigation files from a different server
(my_domain2), then I get an error and the name of the files are not shown.
When I try it with Apache on my local computer an error is shown on the
first line
 $handle=opendir("http://domain2/navigation/";);

Is there an other way of getting the filenames from a different server? The
directory structure at my_domain is equal to my_domain2. Apparently the
function opendir is not correct, can someone help me?

Thanks in advance,

Andr�

The function is correct, BUT, it looks like you are trying to run this
script off one server and then attempting to "feed" the function a
directory structure off another server.

Your code will work "as-is" if you run the script off my_domain2, but it
won't work if you run it off my_domain asking for a directory structure
located on my_domain2.

I am not sure that opendir() can work like this, and you would probably
need to look at some remote file functions like the ftp functions...

Thanks for your reaction,

You are right about your conclusion how I think the code should work. I am
indeed trying to run the script off one server (my_domain1) and then
attempting to "feed" the function a directory structure off another server
(my_domain2).

I suppose the function opendir() only work for a directory at the same
server. When someone can tell me what I can do best. Because I just started
with PHP and I read this code in an example, I realy need some help if you
tell me to use ftp.

Probably your problems about "i can send about seven messages per second"
may be relationed to
OS's tcp connection stream buffering... try to flush every fd after write to
it. I wrote a multi-threaded (pcntl_fork())
application in phpcli using many sockets and they worked well... array
iterations are fast and easy too, as they have
only one level... so I believe that this is really relationed to socket
flushing stuffs...you can also use select() to determine
when a fd is ready for write and implement a "write spool"... only a ideia,
but probably will spent more time with the same
results... well.. flush then may resolve it.

Has anyone experienced exclamation points ! in their emails from no where?
This is a really strange thing I have been noticing lately in emails I send
to myself via PHP.  When I send an email from 2 different machines using 2
different smtp servers, I still get the exclamations in the email.

Any ideas what on earth is causing that?

Example:

the!ir is an ex!clamation in my e!mail that I did not pu!t there.

Why??

Thanks!

Hi,

Did you try using the system() command instead and skip using exec and
passthru?

Hi,
I have a small (simple?) doubt, if you know the answer kindly reply.

I have a top.php and bottom.php template files so that the whole site has
pretty much the same look and feel, then I have around 150 scripts that call
this files such as index.php or something.php like so:

<?php
session_start();
include "top.php";
subject or page matter here
include "bottom.php";
?>

I am relying heavily on sessions, right now its become an habit for me to
have session_start(); on every page as I start to write it, but have started
seeing some funny results as I have a session_start(); in both the calling
file and the top.php....

do I really need to have it in both or just one?
or does it really matter at all?
 if just one it should be the file that is calling top.php right?

Thanks,
-Ryan A

Just one, the calling page/script

--- End Message ---

--- Begin Message ---

In PHP >= 4.3.3 versions, start a session when you have a session started already, 
causes a notice error and the second call is ignored.

In older versions, the second call is ignored without errors (assumes the first 
session started)

Put this to your top.php:

@session_start();

And then, remove all the session_start from the others php files, when you are done, 
remove the eat '@' in the session_start() (isn't smart)

I'm unable to answer that. Some knowlege of what exactly the error
is might help. The headers shouldn't cause error.

be a problem...

i've tried asking this in the phpBB and apache forums
but they can't think of a fix. all that's left is
PHP,.
i hope u guys can help
i've spent 4 consecutive nights reading manuals and
mining the net for a solution but all i found was 1
other person wiht a similar problem on google's usenet
thingie...who also got no answer

im not sure when this started coz no one told me about
it before...
HELP! my exams start in 4 days and i can't get any
sleep coz of this ...

 I currently limit file types in an upload script by using an allowed
types array

$allowed_types = array("image/jpeg", "image/gif");

 I also need to allow files of with the following extentions.

 .tif, .pm7, .p65, .pdf, .qxp, .pmd, .eps

Is there a site out there anywhere that gives the mime types of theses
files?

Thanks,

You could use the function exif_imagetype() to see what type of file has been uploaded.

Did that as well as googled for the list of extensions. Still can't seem
