Re: [PHP] session question
There is a useful article here: http://phpbuilder.com/columns/ying2602.php3?page=1 As to "up to a million users" logged in at once... don't you wantto have multiple redundant web servers running under a load balancer? If the rest of your system can handle that many concurrent users, then I doubt PHP sessions will be much more of a strain on your system... unless you're storing some huge amount of data in each session.

Re: [PHP] Form security
Are you using sessions? You can register a tracking variable on the form page and then check that variable on the processing page. If the posted data comes from any page other than the one that you want it to, the variable will not be set. Not 100% sure, but I think this covers what you've asked. Pete.

Re: [PHP] Interesting Problem (Sessions and Cookies)
You can indeed do this in javascript. You need to put a FORM on the page in the other frame and then access the data elements in that form with the syntax parent.frame[x].formname.elementname.value or something along those lines. This gets pretty ugly pretty quickly, IMO. Also, I think you could run into some real problems if the user opens multiple browser windows for these pages... you could easily get data that is out of sync with what is stored on the server in the example you gave if the user opened two windows and began modifying the data in the two forms in both windows. I think you'd essentially be swapping one set of problems for another set of problems. Pete.

Re: [PHP] PHP & XML Parsing
> Interesting.. So to be consistent with proper XML formatting, > should the server hosting the XML file convert the & into > & ? It depends on the situation, I believe. The server that sends you XML should indeed provide you well-formed XML, which it's not doing. Probably what should happen is that the server sending the XML should urlencode URLs in the cdata elements, and then after you parse the XML file you should urldecode the URLs. I would be surprised if this hasn't been done as some standard part of XML parsing and I've just missed it in my limited use of XML parsers. > I certainly feel like I'm missing something... Although I'm a bit at > odds as to how to troubleshoot this new file. > I no longer get the errors, but I'm not getting the results I'm looking for either. I'm not sure what results you're looking for exactly, but if you put in a bunch of echo statements at various points throughout your parsing routines, you will see that none of the "if x = y" conditions are matching. Here's what I'd recommend: 1. put in a bunch of echo statements to print out your variables at different points in your parsing, just to make sure it's doing what you expect it to. Do a full audit of your characterData routine through this method, and I think it will show you where the errors are. (I did not see the exact error right away so I gave up since I do have a day job. :-) 2. keep your first eregi_replace statement, then when you're printing out the links, re-convert it with a reverse eregi_replace to turn the & back into a simple &. This will send it to the HTML browser in the format you want, I hope. I hope this is of some help.

Re: [PHP] Passing variables
You can "pass" variables through the session mechanism. http://www.php.net/manual/en/ref.session.php This will require some additional work to get your sessions working properly, but you probably want to do that anyway at some point. I have found the session mechanism to be extremely useful so far, though to this point it's only been in a development (not production) environment. Pete. PS: If you want to get really ugly, you can have all your links actually be javascript functions that submit a form full of hidden elements via POST. Uglier and more bug-prone than including them in the link URL, but you don't run into URL length limits and you don't get people quite as easily changing the values to see what happens. > Is there any other way of passing variables other than submitting them > through a form and passing them using a URL?

Re: [PHP] Class var not retaining values
Could it be that you need your for loop to iterate <= instead of < ? As it
is, I don't think it will ever show anything. After all, you are setting
$index to 0 at the beginning of the function every time you call it.
My guess is you actually want to keep track of $index as an instance
variable outside the function and reference it via $this->index in all the
places where you have $index.
class AR {
var $index = 0;
function AddReason($score, $reason, $id)
{
$this->reasons[$this->index] = "$score|$reason|$id";
for ($i = 0; $i <= $this->index; $i++)
{
$out = $this->reasons[$i];
echo "$out...";
}
$this->index++;
return $score;
}
}

Re: [PHP] PHP & XML Parsing
The problem is in your link URL, where you pass CGI parameters. When XML sees the & character, it assumes it's a special character thing such as & or ", so it's expecting a semicolon. http://cupe.ca/news/cupenews/showitem.asp?ID=2823&cl=1 Just yesterday I discovered a program called XML Spy which you can get on a 30-day eval from www.tucows.com. This was what pointed out the error to me in your file. When I was using XSL last year for the first time, I had a devil of a time figuring out how to get URLs, particularly with query strings attached, through the XML parsers. Try using the %codes in your URLs instead of & and other special characters; that should help, if I remember correctly. (Similarly, building HREF tags using XSL stylesheets seemed pretty awkward, but I'm sure I was missing some crucial tidbit of information.) Pete.

Re: [PHP] Why is this not working
can you write directly to the password file using crypt() instead of trying to run the htpasswd program? I think I used to do this in Perl, but it's been a LONG time since I tried it. I think it worked, though. Pete. PS: I'm also pretty sure that if you can't write direclty to the .htpasswd file, you can specify multiple password files in your .htaccess file, and you should be able to write to an alternative password file.

Re: [PHP] References & Object XML-Parser
I am new to PHP's OO (though not to OO or to PHP), but here's a fix and my
assessment of why it works:
In your tag functions, you need to change the $this reference to instead
refer to your $xml_parser object, thus:
function tag_open($parser,$tag,$attributes) {
global $xml_parser;
$xml_parser->result .= "TAG: ".$tag."";
}
My speculation as to why this happens is that the actual parsing is going on
in the parser object you create in the xml() function. The tag_open
function is being called not as a method in your xml class but rather as a
simple callback function, so it does not get all the context of the xml
object... instead, it has the context of the parser object. So if you bring
the $xml_parser variable in as a global and then use it to set your result
variable, you should see the results you're looking for (I did).
Pete.

Re: [PHP] PHP & Java ?
If it's javascript, then be careful about echoing PHP variables into Javascript strings. If you have something like (in Javascript) var myString = ''; and $phpString contains any apostrophes, then the javascript will break because Javascript thinks the string has ended prematurely. E.g, if $phpString is "My cat's pajamas" then the javascript would be sent to the browser thus: var myString = 'My cat's pajamas'; and you can see that there are too many single quotes, which will, of course, cause Javascript's high-powered debugging utilities to kick in and give you a highly useful error report.
