Subject: Re: [PHP] try - catch is not so clear to me...
Basically try-catch gives you the ability to handle errors outside a class or
method scope, by the calling instance.
This comes in handy, if you are programming in an object orientated way and
thus enables you to seperate error handling from the rest of your functionality.
Means, your methods do only the things, they are meant to do, without bothering
to handling occuring errors.
Hope, that made things clearer.

While I don't disagree with the when's here of GET vs POST, this statement is a bit misleading... Any cracker worth his salt can easily install any number of Firefox extensions or unix command line tools and not only view the POST data, but alter it as well. So if you are sending something like a password, don't think that it's secure just because Joe Average doesn't see it. If you're not using SSL, then it is sent as plain text like everything else. And don't assume that what you presented on a web page in select boxes and other form elements is the ONLY thing that is going to come back to your server to process. It's trivial to mangle the data. This is what SQL injection is all about. http://en.wikipedia.org/wiki/SQL_injection http://phpsec.org/projects/guide/3.html Daevid. http://daevid.com It also should be noted that post is not automatically secure against csrf attacks. While most csrf attacks are get, they can and do happen via post as well. I agree that passwords need to be sent via SSL. Unfortunately most users use the same login and passwords for many sites. So even if your site doesn't otherwise need SSL, using SSL for login helps protect your users. For me the biggest advantage of post is the URLs aren't ugly. For cases where get with a variable in the URL is useful (IE product=BluePhone) - I prefer to handle that via mod_rewrite. The requests get handled by generic.php and generic.php then looks at what the requested URI is to figure out what otherwise would have specified by a get. Just as linkable as ?get=whatever and a lot prettier for the user to look at in the url bar. I think doing it that way also has search engine indexing advantages. I've done a bit of research into that, and can't find any evidence to suggest that the so-called friendly URL's are actually of any benefit to search engines. Just put a question into Google, and more often than not, the top few results are from forums, which tend not to use these friendly URL's. The only reason one might help with SEO is the case where a site is being redeveloped or re-versioned, and you need to preserve old page names to retain any ranking the site once had. Of course, I'm welcome for any evidence to the contrary, so if any of you have stumbled across links to any of that...

Would this function work for sending html and solve the utf8 problem?

I'll try it and see what it does.
this was the only workaround I received for the moment, and I was a

I find that IE7 (at least) is pretty reliable as long as I use strict XHTML and
send a DOCTYPE header to that effect at the top - that seems to trigger a

Re: [PHP] https and Credit Cards
Hi, I've always put any forms that collect credit card information behind a secure connection, https, figuring that sending that information from the client browser to the server should be secure, but I'm having convincing a client that it is necessary. He instead insists that only the call to the credit card processor's server needs to be secure and of course the processor supplies the connection there. But doesn't also the form need to be secure since you're sending CC information from that form back to the web site's server? Yes. Any connection to you where your punter supplies CC details should be secure. If the punters ISP runs a transparent proxy for example, then these details could be easily captured if not sent over a secure connection. -- Richard Heyes HTML5 Canvas graphing for Firefox, Chrome, Opera and Safari: http://www.rgraph.net (Updated April 11th) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] $_GET verses $_POST
$_REQUEST is not any less secure then $_POST/$_GET/$_COOKIE, they all contain raw user data. The way $_REQUEST is being used in this example is not less secure then using $_GET. It does open up an exploit but this is not because $_REQUEST is less secure. The same exploit exists with $_GET, I could place an image on the page with src=?act=logout. $_REQUEST has a place but it should not be used as a direct substitute for $_GET/POST etc, unless you want the user to be able to have all the options of posting data to the server. 2009/4/14 דניאל דנון danondan...@gmail.com $_REQUEST is less secure because it also contains cookie data.

[PHP] Reflection question
Hi, everyone!
I need to do the following:
Let's say I have this class:
class A {
public function b(array $c, $d = 6) { ... }
}
I need to get this in runtime:
public function b(array $c, $d = 6)
What's the best way to do it?
(I don't quite like the idea of reading the file in which the class is
defined and it might not always work...)

Well, this would happen if you open

that way the var is set and a part of the _GET Array. You might want

Hi PJ,
Maybe you should post your code, or portion thereof. The trained eyes on the

Maybe you can also sacrifice some of your data or data structures if not too

short_open_tag is not deprecated.
What if you want to use ? foreach ($x as $y): ? in your template?
There is no point removing ? and not ?= at the same time, since a
large portion of code would be broken anyway (and NO, I am *not*
suggesting removing either!).
Use % if you want a short tag.

Remove short open tag, but leave ?=get('blah')?. Bacicaly PHP parser
should look for ?php or ?=, single ? is not allowed. That way:
1). short_open_tag is gone for good as an option in .ini.
2). Making templates doesn't suck
3). Backwards compability with old templates is preserved (old templates
with ?= work fine).
4). ? in code is broken as you want it to be and makes coders fix it with
?php
Everyone is happy, XML and others are safe.
Yes, it's really irritating to write ?php echo every time!

your answer lies with not replacing foreach to make your life/output

will snag it complete from the other thread.

Hi Jim,
Please excuse my writing to you directly. If you don't think it's
proper, just let me know I'll swing off.
No problem with hitting me directly, but your findings could be of use
to others
since it is cleaner way of solving your problem.
So, on the list we go
So, while I have your attention and if you have a moment, I found this
interesting possibility: someone threw implode() at me and I looked it
up in the php manual and hey, found and interesting little function:
function ImplodeProper($arr, $lastConnector = ' ')
{
if( !is_array($arr) or count($arr) == 0) return '';
$last = array_pop($arr);
if(count($arr))
return implode(', ',$arr)., $lastConnector $last;
else
return $last;
}
Since my limited understanding of php impedes me to implement it
experimentally in my application, I was curious if, indeed, it could be
another option. It does look to me like it could work, but it would
require a slightly different implementation of the query, probably
somehow using something like a CONCAT(first_name, , last_name). Am I
learning something here or is this the wrong tree to bark up?
This would be a very nice way to clean up the code
Although you could do something with CONCAT(), I would suggest leaving
the code as is.
Data is all that you want to get from MYSQL, not format.
Basically, take the above function and place it in a lib you include
for everything. Then replace the if/then/else statement that I built
for you with a
call to said function.
?php
...
function ImplodeProper($arr, $lastConnector = ' ')
{
if( !is_array($arr) or count($arr) == 0) return '';
$last = array_pop($arr);
if(count($arr))
return implode(', ',$arr)., $lastConnector $last;
else
return $last;
}
...
# Test to see if the book has any authors
if ( isset($authors[$bookID]) ) {
# Tell us how many authors we found
echo 'Found: ', count($author[$bookID]), ' authors';
# Create an array that will hold the output from the DB.
$aList = array();

Good suggestion Leon, thanks.
I can certainly do that, np. Nothing sensitive. I do have quite a few
questions about the code I have used. Things are moving along very well
and I should be able to put up the code on the actual site in some
directory where it will be possible to view the code and see what it is
doing. I'll post the link when more or less ready and then ask for
comments, observations, suggestions . Posting the code on the list would
be too bumbersome. For now, I'll stick to some snippets. :-)

I don't know much about active directory but I thought one of the points
of AD was to eliminate the need for a user to log in since they are
already authenticated by the centralized AD system.
If you want to use active directory as the only user authentication
method then as long as the browser sends the credentials it will verify
and the user is logged in.
You could probably use password _in addition to_ active directory to
authenticate a php session, allowing you increased security over just a
session token (IE browser has to send valid php session AND active
directory credentials) but if you want a user to have to login in
addition to active directory credentials, use php sessions on your
server, and upon succesful login w/ proper AD credentials set a session
variable that says they are authenticated.
When they log out, unset the session variable that says they are logged
in and expire the session. Then regardless of their AD credentials, they
will have to log in again to be verified by the session system.
SSL doesn't do anything magic as far as user authentication is
concerned, it simply provides a public/private key encryption so that
(theoretically) only the browser can decrypt what the server sends and
only the server can decrypt what the browser sends.

[PHP] count() total records for pagination with limit
I seem to recall that it is possible to count all instances of a query
that is limited by $RecordsPerPage without repeating the same query. I
believe that COUNT() had to called immediately after the SELECT word but
I neglected to bookmark the source. Dummy!
I don't like the idea of count(*) over count() or something like that as
it seems rather slow fram what I read.
right now I do this:
$sql = SELECT * FROM book
WHERE id IN (SELECT bookID
FROM book_author WHERE authID IN (SELECT author.id
FROM author WHERE LEFT(last_name, 1 ) = '$Auth')) ;
$Count1 = mysql_num_rows(mysql_query($sql, $db));
$books = array();
$SQL = SELECT * FROM book
WHERE id IN (SELECT bookID
FROM book_author WHERE authID IN (SELECT author.id
FROM author WHERE LEFT(last_name, 1 ) = '$Auth'))
ORDER BY $sort $dir
LIMIT $offset, $records_per_page ;
if ( ( $results = mysql_query($SQL, $db) ) !== false ) {
while ( $row = mysql_fetch_assoc($results) ) {
$books[$row['id']] = $row;
}
}
$Count = mysql_num_rows($results);
$Count gives me the actual rows for display - $Count1 gives me the total
rows available.
Can this be streamlined any?

[PHP] PDO fetch_obj - question
Hi there, Ive made a fetch_obj and, as stated on some sites, it returns a anonymous object where the properties will have the name of our columns database. However, when I do this, I notice that instead of giving me the column names as they are typed on the DB I get them uppercase. So, when my database field is id_dog to retrieve the property properly I have to search for ID_DOG Why is this? Is this a normal behavior? Thanks a lot, Márcio

foreach doesn't give a damn about count so you can't use that - it is

Look again at the code - the count() is not inside the foreach, so it is
not reset, simply stored in $lastIndex for comparison.
If your array is associative then simply use another variable to find the
last value in the array - the code doesn't need to change much.
Try actually running the code below - it does work, as does the previous

Re: [PHP] Generate XHTML (HTML compatible) Code using DOMDocument
Hi,
I'm thinking about using the html5 doctype for all html documents since it's
supported by all the popular browsers available today.
Two Quick questions...
Why do we need to send XHTML code to a web browser when standard html code
(with html 5 doctype) will do just fine?
Is there any advantage of using xhtml in the web browser over html for normal
web application development?

Why do we need to send XHTML code to a web browser when standard html code (with html 5 doctype) will do just fine? In most cases we don't. However if we want to include extensions (such as MathML etc.) then xhtml is the only way to do it. My own reason for sending xhtml is because I believe it to be a superior specification and would like to see html (where not all tags need to be closed) go away. Having valid x(ht)ml output also means that other software that uses your web page as a source for data can just parse it as xml to get the data it needs. Be careful with html 5 - use the fallbacks (IE embed or object for video as a fallback to the video tag), because not everyone uses the latest browsers. Is there any advantage of using xhtml in the web browser over html for normal web application development? In most cases, not a display advantage. HTML 1.1 supports the ruby tags/attribute, html 4 does not, but with html 5 / xhtml 5 - they are supposedly identical in spec with the only difference being the markup semantics of xhtml 5 conform to xml standards. I suspect html 5 elements/attributes are case insensitive (like they are for previous html) but I haven't checked - xhtml tags/attributes need to be lower case. But if your page can be properly displayed with valid html then the only technical advantage I can think of for using xhtml is for apps that use your page as a data source (so they don't have to convert it to xml). I personally will send xhtml most of the time when I can because I want HTML to go away, and as soon as 97% of browsers properly support xhtml, I may stop sending html all together. Since IE 8 still does not (not will correct mime type anyway) it will be years before that happens. Oh - another advantage to xhtml - it's easy to extend for your own use. For example, you can add a custom attribute for your own use (IE as hooks for other web apps on other sites to use when grabbing data from your site, or whatever) and it will validate as long as you properly declare it. With html, I believe adding an attribute is not allowed unless you create a whole new DTD. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Generate XHTML (HTML compatible) Code using DOMDocument
As michael said my main reason is strictness. It's much easier to
parse a document when an XML parser can read it. I like the idea of
closing tags etc.

The above outputs the following: plaintextxxx xx x xx xxx xx x x xxx xx xx xx xxx xx xx xx Array ( [0] = Array ( [0] = xxx xx x xx xxx [1] = xxx [2] = [3] = xx [4] = x [5] = xx [6] = xxx ) [1] = Array ( [0] = xx x x xxx xx xx [1] = xx [2] = x [3] = x [4] = xxx [5] = xx [6] = xx ) [2] = Array ( [0] = xx xxx xx xx xx [1] = xx [2] = xxx [3] = xx [4] = [5] = xx [6] = xx ) ) Hope this is what you are looking for.
