Re: [PHP] users online
Ryan A schreef: Hi, I have been searching the archives with little luck so I need a reminder here, I remember a little while ago someone asked how to implement the users online functionality that some sites have...now i have been asked to do exactly that but with a small twist: instead of displaying xx number of users online they want me to display all the usernames who are online with a link to their profile. I have a few ideas on how this can be done, but I would like advise from people who have already done this or thought of doing it (i think there was also a class that does something like this i'll check while waiting for a reply from you guys) so i can compare it with my ideas (which are in the infancy stage ;-) ) Easiest way of doing this is adding a 'last seen' field to your user profiles and updating that record with the current timestamp every time the user requests a page. Al you need to do when displaying the 'users online' info is getting al profiles with the 'last seen' record on a time between now and x minutes ago (depending on what you consider to be an 'online' user). If you're using a database like mysql or postgresql for profile storage, use a field type that the database software can handle internaly, this can speed up the query. regards, Ewout -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Strange results from file_get_contents using an url as filename
I'm getting unexpected data from my file_get_contents function using an url
as filename.
The function does not return false, i do get data from it. Problem is that
is is not the data is requested.
$data =
file_get_contents(http://somehost.com/xmlonl.asp?custid=00prodid=0
);
if ($data)
{
...
the string this function returns is the webpage from the default website of
the server where this php code is running at and not the data from the
remote site (which is not on the same server).
i tried the url from my shell on the server using telnet and it gets the
data i expected.
I can't figure out why php is getting the wrong results while telnet on the
same host gets the correct data. Is this a (known) error with php or is it a
apache/php/server configuration problem ?
regards,
Ewout

The default location for php to store session data is the tmp directory of the host os (like /tmp), and in most cases these files are readable by the webserver... and by all other scripts it's running. So if you're hosting your site on a shared server other users can read your session data, that's fine as long as you don't use it to store critical information like username, password some more info on this topic: http://shiflett.org/talks/phpworks2004-php-session-security/ regards, Ewout -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] PHP Auth with Apache
PHP sends a '401 Authorization required' to your browser (just like apache)
and it also gets the user/password info
Code example:
?php
if(!isset($PHP_AUTH_USER)) {
Header(WWW-Authenticate: Basic Realm=\Secret Page\);
Header(HTTP/1.0 401 Unauthorized);
echo You did not log in correctly...\n;
exit; # exit wil stop php from parsing the rest of the script
} else {
echo Hello $PHP_AUTH_USER. You entered $PHP_AUTH_PW as your
password;
}
?
In this example no user/passwd checking is done... just replace the
'welcome' message with your mysql/ldap check routine and voila !

Subject: Re: [PHP] PHP Auth with Apache
I'm now understanding how you can get PHP to present you with a username
and password promt just like APache would do if you had a .htaccess file
in the directory you were trying to enter. Great idea but it seems that it
would be easier to just use the .htaccess file in the directory.
What I've been trying to find out is how to pass through a .htaccess file
if someone has already passed an database authentication lookup in PHP.
I have an area on my site Special Publications where users login and
their username and password is checked against a MySQL database. One field
in their user records is the URL to their directory on our server. Each
one of these directories is protected via .htaccess. What I would really
like to do is have them redirected to their URL if they pass
authentication and not have them enter their username and password again.
Is their a way to do this?
Thanks,

Re: [PHP] Regular Expression trouble
You could exclude the '}' sign from the expression
$content = ereg_replace(\{[^}]*},,$content);
This should do the trick... i'm not 100% certain about the '[^}]'
expression, but you should find it in any regexp tutorial

Subject: [PHP] Regular Expression trouble
I'm trying create form template as I have seen recommended in many
places. It seems fairly simple but I can't seem to get ereg_replace to
work the way I want it.
I'm starting off easy and I want to use the sample template for entering
a new record or editing an existing one. If they are editing, then I
obviously want to populate the form fields with values. If it's a new
entry, I don't want any values. Simple enough.
A form entry looks like this:
input type=text ... value={Name}
input type=text ... value={Title}
So I load the template into a variable using ob_start(), etc. I assumed
that to clear out all the value declarations I would simply do this:
$content = ereg_replace(\{.*},,$content);
But it seems to be replacing everything between the first instance of
{ and the last instance of }, rather than each instance of {}. I've used
regular expressions before and I even tested it using grep in BBEdit 6.5
and it works as I would expect. I'm using PHP 4.1.2 on Mac OSX 10.1.5.
