[PHP] SDO_DAS_Relational limitations
Hi, I'm looking into the SDO implementations and walked into the limitations very quickly. Limitations: - No composite key possible - Only one Foreign key per table - No way of setting up a many to many relationschip My models violates mostly and most likely all of this limitations. So I ask myself. Is it usefull or don't I understand the stratergy? what to do with the many to many relationships, the composite keys and multiple foreignkeys per table ??? kind regards Jeroen Olthof -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

They assume that the user wants to re-use the values THEY entered, not the ones that were the original default. That's what an input type=reset / was designed for into the HTML spec in the first place, after all. You can get them to switch to a browser that behaves like they expect. You can educate them to understand that their browser is supposed to work that way. You can give them a reset form button to put things back the way they were.

[PHP] dynamic case statements?
Hello,
Would anyone know if it's possible to have dynamic case statements?
For example.
Theform = new form();
$temp = $_POST['var1'];
switch ($temp) {
case status:
$theform-status();
break;
case $temp:
$theform-form($temp);
break;
}
This keeps giving me Call to undefined method form::form() in
/usr/local/www/data-dist/form.php on line 38
Line 38 is right after case $temp:
If I have case temp: error goes away, so I get the feeling case doesn't
like the variable $temp.
Any help would be appreciated. Thanks!

Your assumption that the same IP is the same session is one explanation... IP in general is useless for identification, much less authentication. Unless you KNOW those specific IPs are static, and only used by one person on one browser, then you need to do much more research to see if people really are switching from Cookie to PHPSESSID (presumably via GET).

Re: [PHP] Creating User Friendly URLS
As a general rule, if you want to see everything useful that is available to you in your script: http://php.net/phpinfo In particular, this will show you the PATH_INFO if it's there, and the REQUEST_URI if that's there, and... If neither of those are available, I don't think you'll be able to do what you want... It could just be a server configuration issue. PHP doesn't really decide what to put in $_SERVER. Your web server puts a bunch of stuff in the environment SERVER variable, and PHP just passes the buck on to you to do something useful with it. Or so I understand it.

So my script will pull my_web_page_title out of the URL, match that against the database, and then display the appropriate contents. I thought I could do this by simply making my link into: a href=index.php/my_web_page_titleMy Web Page Title/a And then stripping out the index.php, and using the remainder for both the URL and the database lookup. But, while I'm sure there are more steps than that, I'm halted initially because I'm not sure where in the $_SERVER array my URL is being stored.

Re: [PHP] Cookie Variables Maxing Out Using IE6
Set your session time out to, oh, 2 years or less (as in the spec, they are gonna ignore you if you try more than 2 years). You could even set *ONE* cookie with all the values serialized in an array, and probably stay under the 4K limit. Then you get people like me who, if a cookie value looks TOO funky, I'll reject it, on the assumption that you are exposing my personal info to your advertising sites for user-tracking. Buh-bye. Try to think about your cookies from the perspective of a paranoid media-believing moron. Like that movie with Mel Gibson, sort of... Because SOME of your visitors are that weird, self included. :-) You can store a Cookie to ID me with something I know is me, and then you know who I am for the next 2 years. That should be good enough. Read the PHP session pages, and the setcookie page, and work out what's best for you, with the paranoid user visitor mentality above.

Richard Lynch responded: Yes. Read the Cookie spec. There's no need for any site to ever send more than ONE Cookie anyway. Just use session_start() and you can store all the stuff in $_SESSION and it's all tied to the one Cookie. Users like me who set the browser to prompt for Cookies will often LEAVE a site that is being stupid and sending too many cookies, unless we really really really need your content, which is unlikely. So you're calling my app stupid, Richard?? lol To clarify, the app is for a small group of known users on an intranet, and yes, they really really need the content. There are 24 check boxes, and each selection triggers a graphical display of radiation levels in a specific area over the last hour. Since the active areas - 12 to 15 usually - don't change all that much over time, I thought it would make sense to have the app remember which boxes had been checked at last launch. I didn't like the idea of using cookies, so I actually have a database solution in place. But I've not dealt much with cookies, and I had some time and tried to use them to solve the problem. That's when I ran into the 20 cookie limit with IE (Having just read the spec, I'm surprised that Microsoft has actually followed it). Unless there's something basic about $_SESSION variables I've missed, I don't believe they would work here. I need to track and remember which boxes are checked between sessions, not within a single session. Someone please correct me if I'm mistaken. Thanks again to Adam Zey for suggesting I serialize the cookie data. That solved the problem.

Re: [PHP] Downloading of PgSQL data for use local (crappy subject line)
For LARGE datasets, CSV or tab-delimited transfers are probably going to be easiest to suck in to the DB. Another option is to just use pg_dump, if you want whole tables. Otherwise, honestly, I'd suggest you just export your data to RSS or XML and let the user choose how to open it up.

The result of an assignment like $result = do_something('hello') is
itself the result you assigned, so you can still compare on that. The

don't think
you actually need the extra set, but I'm not sure.
Of course you do -- without them, it's the equivalent of:
if ( $result = (do_something('hello') !== false) )
which will only assign TRUE or FALSE to $result.

Some might suggest using JavaScript and storing the hint and solution with that. However, then it is easy for the student to cheat.

Re: [PHP] Re: Session issues
Don't be sorry, that's not what I meant. The fields are completed by the user, they submit and the cleaned and validated values are put into the session. So when they go back their entered values are displayed. I made sure of it by making sure these pages are never cached. That issue is resolved. Now the only problem is that when the client completes the cycle blank or default values are entered into the db, whereas the other 4 remote testers have entered the data without issue.

That's what an input type=reset / was designed for into the HTML spec in the first place, after all. You can get them to switch to a browser that behaves like they expect. You can educate them to understand that their browser is supposed to work that way. You can give them a reset form button to put things back the way they were.

But in this case, we're talking about structuring the data in a PHP-specific data structure for easier application development. Last I checked, SQL has not yet Standardized on an Array datatype, much less all the major players actually IMPLEMENTED that Standard... If you didn't detect the dripping sarcasm laden in the preceding sentence, you haven't looked at SQL Standards versus actual implementation much... :-) For one thing, munging data in PHP means you MUST have a complete copy of the result set in memory, instead of processing it row by row. No, no, no. We're just re-arranging the elements of the same result set from a 1-D array into a nested array! We're certainly not snarfing down the whole table and letting PHP sort it out! PHP's 8MB memory limit can sometimes pose a problem if that munging involves several copies of the data floating around. Yes -- But if you are loading in enough elements of a result set that the difference between the $result and the spliced $result matters, then you've got problems already. Also, the default 8M went up to 16M yesterday in 5.2.0RC2 and 6.0.* because you can't even [mumble mumble install PECL? mumble mumble] with 8M... At any rate, you're not quite envisioning the right thing here... Further, database servers are, in my opinion, easier to distribute than web servers if load is an issue. While your single script could easily connect properly to a database cluster, distributing the PHP scripts involves somehow getting the client to the right one, either by roundrobin DNS, or some sort of redirection mechanism. Actually, in this case, I'm pretty sure we're not looking at an N-tier architecture... If we are, you'd have to rsync the PHP scripts, but that's about it. There's no heavy lifting going on in PHP -- Just splicing an extra array super-structure into part of an existing single result row. BEFORE: $result = mysql_fetch_row(); AFTER: $result = mysql_fetch_row(); $pictures = array_slice($result, 3); $result = array_splice($result, 3, 3, $pictures); I suppose you could unset($pictures) to free up a single array of 3 strings, if you want to get real anal about the RAM... I also tend to think that the database would be faster. Perhaps the PHP script would only a few milliseconds longer than the database to process the data, but when you have multiple requests per second, those few milliseconds can REALLY add up. I'd rather spend the processor time on the webserver gzipping the data as it goes out. Of course, I have no benchmarks telling me that PHP would be slower than a database server for messing with data, I'm just making an assumption. Your assumption is correct, in general. The DB should do any FILTERING / SORTING of large-scale data. But there's no way you're going to construct a SELECT query to get back an array of SOME fields from a single row pre-populated in PHP that will work across SQL platforms, and even if you get it to work in one specific DB, it's going to be a close call as to whether there's any savings at all in the DB building an array so that PHP can detect that array and build that array in C, and a couple calls to array_s[p]lice to build that array in PHP code. NOTE: The issue of having 3 fields named 'picture1', 'picture2', and 'picture3' being a sure indicator of a badly-designed not-so-relational database schema is being completely ignored here, until now... :-) -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] OT alternate website authentication methods
Hello, Last night I was reading Chris Shiflett's PHP Security book from O'Reilly and got to thinking about ways to authenticate a user other than using a password. Ideas: 1. Use flash to allow the user to draw an image. If the original image created during signup is within an acceptable range of the image used to authenticate, let them in. 2. (I saw this somewhere else... don't remember where or what it's called.) Use flash (again) to allow the user to click on an image in certain places. I think it was that you clicked the image in three places and then when you later authenticated you were supposed to click in those same places plus one more (to throw off anyone looking over your shoulder I think). As long as three of the 4 places clicked matched your original points (within a certain tolerance) you were authenticated. I'm not sure that these systems are any more SECURE than a simple username/password combo (keep in mind though, you'll also need some kind of username) but at the very least it seems that it could be more usable. I'd be interested in hearing your thoughts as well as any links for further reading. Chris. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] e-Commerce password standards?
My boss has asked me to seek out any reputable Standards-based documentation for end-user passwords for an e-commerce site. In particular, this site allows users to login with username/password and order food with their credit card on file. So we want to force them to use suitable passwords on their accounts. I've searched some of the obvious candidates, found nothing much, and am in the process of determining at least some of the basic rules for other similar sites. Of course, some of the rules might be like: If they haven't logged in for over 6 months then blah blah blah. I'm not going to be able to determine that in a realistic time-frame. Is there any sort of guide-line documentation maintained out there for specifc use-cases? Obviously the use-case of the password matters a great deal -- an ecommerce site minimum standard is hopefully more stringent than some stupid blog or something... But surely the Banks aren't all just making up their own rules as they go, are they?... -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

nothing wrong with this. like Adam mentioned you can check the expression to see

so:
if (do_something('hello') !== false) {
}
or
// some consider this safer because accidentally assigning

if (false !== do_something('hello')) {

to make the 'safety' issue clearer consider these snippets:
if (false == $res) echo boo!;
if (false = $res) echo boo!; // typo with fatal!
if ($res == false) echo boo!;
if ($res = false) echo boo!; // typo with no error but your logic is
silently borked!
The issue is whether or not this is a safe test. My initial thought is
that it is safe since I'm simply checking for true/false-ness. I either
check for '!== false' explicitly or (in the case of the latter example)

It's slightly less readable but it seems more efficient (if nothing more

readable is probably a question of preference and what your acustomed to; in
situations where you don't need $result you can save on creating a variable by
testing
directly on the return result of the given function.

[PHP] call_user_func_array on STATIC method
Does anyone know of a way to call a static method with an array of objects? I thought for sure this would work, but it does not: $v = call_user_func_array($class::$method,$params); Do I have to resort to eval()??? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Robert,
Isn't it to easy to cheat if you do like this? Just view the source and you
have the answers. But, this is maybe not for examination, maybe just for
learning. If it is examination, AJAX would be better, so that they can not
find out the solution by just looking at the source.

Hello,
I am working on a php project that needs a little
extra JS/DHTML solution. I am sure some of you might
have come to use something like this before, please
recommend a solution (commerial solutions are fine /
willing to pay)
Basically, I will have a page with around 10 questions
for students and then two buttons for [HINT] and
[SOLUTION]
When either of these buttons/text is clicked the
resulting text should be displayed in the side/bottom
cell, the user should also be able to 'close' this
resulting explanation.
Note, on each page there will be around 10 questions,
so each of these questions will have a hint solution
button/text.
Will you have two buttons for each question? So that you get the
hint/solution on a question by question basis? The solution is quite
simple:
html
head
script language=javascript type=text/javascript
var hints = new Array();
hints[1] = 'Hint for question 1';
hints[2] = 'Hint for question 2';
hints[3] = 'Hint for question 3';
hints[4] = 'Hint for question 4';
//...
var solutions = new Array();
solutions[1] = 'Solution for question 1';
solutions[2] = 'Solution for question 2';
solutions[3] = 'Solution for question 3';
solutions[4] = 'Solution for question 4';
//...
function showHint( id )
{
hideSolution();
var h = document.getElementById( 'questionHint' );
h.innerHTML = hints[id];
h.style.display = '';
}
function hideHint()
{
var h = document.getElementById( 'questionHint' );
h.style.display = 'none';
}
function showSolution( id )
{
hideHint();
var s = document.getElementById( 'questionSolution' );
s.innerHTML = solutions[id];
s.style.display = '';
}
function hideSolution()
{
var s = document.getElementById( 'questionSolution' );
s.style.display = 'none';
}
/script
/head
body
pblah blah blah blah blah blah/p
p
Question 1 ...
input type=submit value=Get Hint onclick=showHint( 1 ); return
false; /
input type=submit value=Get Solution onclick=showSolution( 1 );
return false; /
/p
p
Question 2 ...
input type=submit value=Get Hint onclick=showHint( 2 ); return
false; /
input type=submit value=Get Solution onclick=showSolution( 2 );
return false; /
/p
p
Question 3 ...
input type=submit value=Get Hint onclick=showHint( 3 ); return
false; /
input type=submit value=Get Solution onclick=showSolution( 3 );
return false; /
/p
p
Question 4 ...
input type=submit value=Get Hint onclick=showHint( 4 ); return
false; /
input type=submit value=Get Solution onclick=showSolution( 4 );
return false; /
/p
p.../p
p id=questionHint style=display: none;
/p
p id=questionSolution style=display: none;
/p
/body
/html
I'll leave it to you as an exercise to adapt it properly in PHP using
variables and loops instead of harded coded content :) BTW, this is not
PHP, but I'm feeling benevolent today ;)
Cheers,
Rob.

It is a small chocolate candy manufactured by the Hershey's corporation. It's also the act of pressing one's lips against the body or lips of another, in a friendly, romantic, or sexual fashion. It can also be a misspelling of a rock band that was popular a while back. It is also an acronym for Keep It Simple, Stupid! I leave the decision of which meaning was intended here as an exercise to the reader.

RE: [PHP] OT alternate website authentication methods
hi chris... it's doable... it's actually quite secure depending on what your app is, and what your user knowledge is... check out www.passmarksecurity.com - -Original Message- From: Chris W. Parker [mailto:[EMAIL PROTECTED] Sent: Friday, August 18, 2006 2:08 PM To: php-general@lists.php.net Subject: [PHP] OT alternate website authentication methods Hello, Last night I was reading Chris Shiflett's PHP Security book from O'Reilly and got to thinking about ways to authenticate a user other than using a password. Ideas: 1. Use flash to allow the user to draw an image. If the original image created during signup is within an acceptable range of the image used to authenticate, let them in. 2. (I saw this somewhere else... don't remember where or what it's called.) Use flash (again) to allow the user to click on an image in certain places. I think it was that you clicked the image in three places and then when you later authenticated you were supposed to click in those same places plus one more (to throw off anyone looking over your shoulder I think). As long as three of the 4 places clicked matched your original points (within a certain tolerance) you were authenticated. I'm not sure that these systems are any more SECURE than a simple username/password combo (keep in mind though, you'll also need some kind of username) but at the very least it seems that it could be more usable. I'd be interested in hearing your thoughts as well as any links for further reading.
