Hi,
I have the following line as the only line in a .htaccess file:
AddType application/x-hpptd-php php3 html
in order for .php3 extension files as well as .html extension
files to be treated equally.
However, what happens is that a box is opened in my browser
for saving the files. It seems that neither the .php3 files nor
the .html files are parsed. What did I do wrong?

Yeah, I guess you're right. I neve intended this to be a secure way of
doing things, just an easy, non-cookie way. I definitely wouldn't use it to
protect anything worth hacking into.

Subject: Re: [PHP3] User Authentication
The only disadvantage with relying solely on this is that ~from what I
understand~ $HTTP_REFERER is quite easy to spoof (I would like to know more
about this, if anyone is an expert. Is it a real issue?). That would make
disabling this security farely easy, ~IF~ you knew that this was the method
being used, ~AND~ you knew one of the valid URL's.

attached mail follows:
Preface: I've already read the documentation (http://www.php.net/manual/html/function.imap-open.html), and I've searched the archives on this subject.
Anyhow, I'm writing the online voting scripts for my university's Student Government Association. Most of what I'll be writing will be accessing an Access database via PHP and ODBC. However, I'm currently writing the front-end to validate students (all voters have to be students).
I'm attempting to login to our mail server on behalf of the user. Then, if the login is successful, he/she has an e-mail account and is thus a student. Partly using some example code from the link above, I made this script:
<?
$username = "my-user-name-here"; $password = "my-password-here"; $mailhost = "mail.vt.edu";
$mbox = imap_open ("{$mailhost/pop3:110}INBOX", "$username", "$password"); if ($mbox > 0) echo "Success!<P>"; if ($mbox == 0) echo "Failed!<P>";
imap_close($mbox);
echo "Finished script.<P>";
?>
However, as you can see from it in action here (http://www.sga.vt.edu/php/test-pop-success.php3), I get "Fatal error: Mailbox is empty in c:\InetPub\wwwroot\sga/php/test-pop.php3 on line 16".
So, what am I doing wrongly? All I'm trying to do is to capture the success/fail result code of the login via imap_open. I mean, it seems to be getting "success", as it should, but why the error message too?
That's not the worst of my problems, though ;). I slightly tweaked the above script -- only changing the password from my mail account's correct password to an incorrect password, to create this version (http://www.sga.vt.edu/php/test-pop-failure.php3). There, as you can see by visiting the page, the script totally dies :(. Why is PHP returning all these error messages to the "user" instead of just setting the output codes?

One thing to remember, if something works in IE but not NS it's not going to be a PHP issue. Always look to the HTML.
In this case you simply forgot to close the <table> tag in your display after the loop.

Well sure you don't check that any of the values have been set. There is no reason why you will get any information from the form so you should make sure that each variable is set using the isset() command.
Secondly, what is: if($value==id){ and so on, it should either be: if($value=="id"){ or if($value==$id){

First of all, passing along string in URls is not generally a good idea. Use POST instead. If you absolutely have to, use javascript:escape(str); BUT, it works only for iso-latin-1. Now that I look into your code, you do use POST. Why put the desc in the href? Put an ID instead. Anyway that's how I would do it:-) -Stathis.

Jeff,
Download them to your site, use GetImageSize, then resize based on some math you do first (so that the dimensions remain in proportion).
Also, ImageCreate only works on gif. I have a system using a console app called convert (comes with ImageMagick I'm told) and Rasmus recommended something else about 10 days ago, but I'm at a loss to remember it. But convert works just fine.

i'm running redhat linux 6.0 on my PII. I installed php3 rpm (php-3.0.12-6.i386.rpm). Then i went on to compile php-3.0.15 for getting the support of ldap and apxs folowing the instructions in the INSTALL.REDHAT file. everything went fine with the installation of the rpm and the compilation of the source. i have even made the required changes in the apxs file and the httpd.conf following the instructions in your FAQ. but now when i start httpd on the computer it says Cannot load /usr/lib/apache/libphp3.so into server: /usr/lib/apache/libphp3.so: undefined symbol: ap_regexec

The header() function can only be used before any other output, so your script would look like:
<?php Header("Location: http://www.php.net"); ?>
Just leave out the <html><body> bit and all should be well. See function.header.html in the manual.

The problem is that HTML headers are the first "things" sent by the server to the browser. When PHP tags are after the HTML document's html and body tags, the opportunity to send additional headers is past. It's like when writing a letter... when you get to the "Dear Sir" part, the opportunity to add info to their address is gone: you are now in the body of the letter.
Headers (and cookies) need to be at the very start of your PHP files, so the below would be:
Header("Location: http://www.php.net");
Now PHP4 allows you to put headers inside the HTML files, but at some performance expense.

Hi, I want to ask a question. When a user is logged into the web site, I want to keep his track while he is visiting the pages of web site. For example, if address of our site is: http://www.php.net After logging into site with a password I want to change the adreess as http://www.php.net?id=101 ( I am keeping login and passwords in a database and every user has a specific id num). How can I do such a thing? Also, this is not a secure way of keeping the track of a user. Because anyone can enter the id of another user in address line and can act like that user. How can I do such a thing in a secure form? For example id num. will be available in all the pages that the user is visiting in the site but it will not be shown in the address line. Not only id variable, but also I want to hold other variables about a user. I am using php3 and apache web server in windows environment.

I am trying to select a series of rows from a MySQL database in a random, what I really want is to be able to send something like SELECT * FROM whatever ORDER BY RAND
It is important that every row is checked, and that no rows are checked twice. CPU use is also very important (it will be in a frequently accessed script, the one that displays banners in a banner exchange)
Any ideas?

There is already some logical selection. It cannot show the site a's banner on site a, and it only checks people in the same zone. This should (and usually does) leave a number of posible sites. The majority of the time, HTTP-referer would be a waste of time because people visit more than one page on a site, so on all subsequent pages http-referer would refer to that actual site. I could do something similar using cookies though, I will have to think about it.
You idea about credits is good, but the number of remaining credits is not stored, rather the banners shown and used are. I feel this is the best way as there are many things which can affect the number of credits, and storing both mean there is a risk of them getting out of sync somehow, I can't store just the remaining credits as the users need more than this.
Anyway, that means I can't use the mysql sorting options, and any sorting I did using PHP code would probably be CPU-intensive (permorming calculations for lots of users)

How am I supposed to configure PHP as a module when there are more virtual webs on the server ?
The problem is that PHP scripts run with the UID/GID apache itself has. Every VW has its own UID/GID, but the files must be readable by apache and thus readable by any PHP script!!
This problem does not affect CGIs as apache can be configured to use suexec (or any other CGI wrapper) to run CGIs as the VW user.
Is there a solution to this problem other than running PHP as a standalone CGI with a CGI wrapper and lose functionality ( Header() -> authentication, whatever ) ?

I asked this same question about a month ago. The short answer is no. To get what you want and you've obviously already figured that out, is to run php as a cgi.
Someone let me know when a SuExec style is available for php3. I know that one has been written for MS FrontPage called mod_frontpage ( for latest ver);
ftp://ftp.vr.net/pub/apache/mod_frontpage/
Possibly someone can modify this to work for php3 - dunno, no coder here.

If this doesnt work when you post to it, try the following url for your script

if that doesnt work, theres somthing wrong with your php.exe or apache installation.
I think that $HTTP_POST_VARS are global so they can be got by globals[$HTTP_POST_VARS]
so somthing like

Hi, php3-users!
In my redirect.cgi I'm calling PHP compiled as CGI. At the shell output all is Correct.
But calling it like http://server/cgi-bin/redirect.cgi I'm getting a garbage liki this:

redirect.cgi correctly call any other program and I try to do thi in 3 ways: 1. via popen() (FreeBSD 3.3.). 2. Via pipe() -> vfork() -> dup2 -> exec 3. Via simple execv()
Always garbarage.
Additonaly I use: putenv("REDIRECT_STATUS=200"); popen("/path/php -ffile.phtml", "r");

You don't call your CGI -- it's just sent to you as a file. Check your server's configuration.

Configuration is OK. Other scripts works in this directory. redirect.cgi works well if it doesn't call "php file.phtml" For example it correctly works with simple: path_info.cgi script, that outputs passed PATH_INFO env variable.
So problem is open :(

It was a feature :))) When PHP is called from shell, then enviroment variable PATH_TRANSLATED is not send and it looks for command line parameters.
When it called via redirect.cgi, called via HTTP, PATH_TRANSLATED is set and PHP miss command line parameters!!!! WHY?????????????????????????????????????????? :) What's a pile?

Hi,
If you go to www.favasa.org.uk - the site I'm building - you'll notice a table on the right which pulls data from a MySql table. When you click "cont", it's meant to take the ID of the news item and display it in *full*. However, it continually displays the wrong one and I don't know why.
The code used is:
$iid_query = "SELECT * FROM news2 WHERE id = '$id'"; $iid_result = mysql_db_query("$dbdb",$iid_query,$connection); $iid_row = mysql_fetch_object($iid_result);
Yet it pulls the wrong ID. Why?!

The structure generated by this function is weird, but easily understood. I tried the following code
$ok = xml_parse_into_struct($parser,"<A attr=\"val\" bla=\"fasel\">aa<B>bbb</B>aaa<C>ccc</C>aaaa<C hallo=\"ha\"/></A>",&$myvalues,&$mytags);
and it worked producing an array myvalues representing the page structure and and array mytags, indexing that structure by tagname. The error handling seems to be a bit obscure: I did not get any error messages when I offered malformed XML. Also, the function does not seem to be able to handle multivalued attributes as in <a attr="agh" attr="ugh"/>. It this illegal XML or a shortcoming of the function?
Your function does represent the XML document as a linear array, not as a DOM tree. This makes reordering operations a bit messy. Is there a particular reason for this or is it just because?

I tried with my standard testfile, which is just below 300 KB in size. That file is being parsed by my code in 5 seconds into a DOMlike tree. Using your function, I get 0.3 seconds with SKIP_WHITESPACE (4300 objects), and 0.6 seconds without SKIP_WHITESPACE(7600 objects).
Very impressive.

They have nothing to do with one another. The first (=>) is an array construct used to assign the term to the left of the symbol as the index of the term to the right of the symbol.
The second (->) is used with classes to access a method (function) or property (variable). The object (class) is to the left of the term, and the method or property appears to the right of the term. Hence, $object->query($query) would run the "query" function defined in the object called "object" on the data passed as the variable $query. Access a property defined in the class as follows: $object->property. Note the absence of the $ symbol on the variable $property. It's as though object->property is the variable name and so it alone has a $ in front of it.
