Are you absolutely certain about that?

   echo strcmp('These are nearly equal', 'These are almost equal'), "\n";
   echo strcmp('different', 'unequal'), "\n";
   echo strcmp('b', 'a'), "\n";

Result:

   13
   -17
   1

The description of the function merely says that the result is <0, 0 or >0
-- it makes no promises about the actual value when it is non-zero.

Cheers!

The Incognito feature wont give you the results you're looking for.

which means you will run into the same issue.

Once you close all your incognito windows/tabs, you will release those
cookies/sessions/memory space and if you open a new one afterwards, then
you will be fine, but if one tabs stays open, no go :(

Have you looked at the http://ca3.php.net/session_name function, and
putting that into your site just after your session_start() ?  I believe
that will fix your issues (as long as your session names are unique),
but i am not 100% sure.

Thank you for this suggestion. This has solved the more serious half of my 
problems; I can
easily generate a different session name for each website, so that the various 
websites
don't interfere with each other, but I have not been able to devise a way to 
differentiate
between multiple sessions of the same website.

For example, if I open one copy of a website as a visitor I am shown as 
Visitor, but if I
then open another window, and log in as Manager, then go back to the first 
window I am
shown as Manager (with appropriate privileges) there also.

The only way I can think of to overcome this would be to generate a new named 
session
every time I log in, and then to pass the session name as a parameter every 
time I load a
new page. Unfortunately my program is sufficiently complicated that this is 
effectively
impractical, as it would involve tracking down and modifying every point in the 
program at
which a new page can be launched.

It also has a theoretical disadvantage that if someone bookmarks a page they 
will book
mark the session name, but this can fairly readily be overcome.

Is there any alternative way in which a different session name (or equivalent 
flag) can be
attached to each instance of the browser?

(Effectively these problems only affect the developer, as they only apply to 
multiple
instances of the same browser on the same PC.)


PS. At this stage I devised a really nasty kludge, which enables me to run 
multiple copies
without them interfering. In my program new pages are always launched by a 
command of the
general type:

http://localhost/cypalda.com/index.php?level=1&item=22

This loads the file index.php, which is a very brief file in the public 
directory
(cypalda.com in this case). It sets a couple of constants and then transfers 
control to a
file Begin.php, in a private directory. This in turn sets up a whole lot more 
constants,
and then transfers control to the main program, which is common to 5 different 
websites.

I realised that if I specify the session name in index.php, I can make several 
copies of
this file, e.g. index.php, index1.php, index2.php, each of which specified a 
different
session name. I thought this still left me the problem of modifying all the 
points at
which a new page was launched, but then I found that by great good fortune (or 
foresight!)
I had defined a constant $home_page = index.php, and always launched a new page 
with the
basic command
echo ('http://www.corybas.com/


Depending upon how your session persistence works, can you not just specify a 
different location to store session data for each possible mode of login?
I have an application which does something similar, and uses a simple file store 
for the session data, so I have 'Manager' session data stored in 
/tmp/Manager/...  and 'User' session data stored in /tmp/User/...  (for example).
It does rather depend on your Manager and User applications not expecting to 
cross over: that is, a Manager can't switch to User mode in the same session.

Try:

Many thanks. Unfortunately, as I mentioned in my OP, the DateTime
class seems to be 'broken' for my purposes because it uses strtotime()
to convert input strings to date/time. Rather than fail when presented
with an invalid date, strtotime() returns the 'best fit' if possible.
This can be seen from:

$date = new DateTime('30 Feb 1999');
echo $date->format('Y-m-d');

which results in "1999-03-02" even though 30 Feb is an invalid date.



If you could programmatically determine the format of the input, you could parse 
the date using DateTime and then rewrite it using the same format as the input, 
and compare those.
Now that starts to work if you can *control* the format of the input, or at 
least limit it to some familiar options.


So maybe:

$userInput = '30 Feb 1999';
$dateTest = new DateTime($userInput);
if ($userInput===$dateTest->format('Y-m-d') ||
$userInput===$dateTest->format('d M Y'))
{
echo 'Date is valid';
}
else
{
echo 'Not valid';
}

It starts to get logn-winded after a while, and doesn't rule out ambiguous 
cases...
Or split the date input into pieces in the form (if possible) and then you can 
validate the date how you like


$userInput = $_POST['year'].'-'.$_POST['month'].'-'.$_POST['day'];
$dateTest = new DateTime($userInput);
if ($userInput===$dateTest->format('Y-m-d'))
{
echo 'Date is valid';
}
else
{
echo 'Not valid';
}


Finally, for some applications I have made an AJAX (javascript + PHP) 
implementation which provides feedback to the user as they type in the date 
field: every time a character is typed in the box, the backend is asked to parse 
it and then format it in an unambiguous way and send it back to the client. That 
way the user can *see* if what they are typing is valid...
Of course, you *still* have to validate it when it's posted (and the network 
overhead might be too much).

Possibly -- or even the result returned by the underlying C strcmp()
for any given architecture/compiler combination, which would like as
not be even more variable.

I think the lesson is, if writing portable code, always allow for
results which might be outside of the [-1, 0, 1] set.

[PHP] best practise accessing object's attributes from objects itself

2011-05-23 Thread Simon Hilz 

hi,

i was wondering if there is any best practise known how one should 
access the attributes of an object from the object itself.
i mean, it is a good practise to write getters and setters for the 
attributes of an object to its interface. but is it common to modify the 
attributes from the object itself directly or also through the interface 
methods? i use the interface methods in my own classes at most times but 
recently i dived into zend framework and there it seems not to be usual. 
as zend framework is more or less a showpiece-software in php 
programming i'm not sure if my practises are good. are there any 
discussions by really focused php programmers about that?

All this confusion makes me glad that I'm using === for equality checks instead 
of strcmp.

It depends on what you need to check, josh :)

If you wanted to say find an anagram, or do a search with some typo
correction, strcmp can be many times more helpful then a ===, that said
comparing 2 strings to be equal === works about 20% quicker, so it works
better for comparing two strings for equality (or unequality) anyways. There
is no confusion, strcmp has a documented way in which it is to work in
posix-compliant languages, ISO/IEC 9899:1999, 7.21.4.2, so as long as you
follow the ISO guidelines for the scrcmp checking, your code should work
correctly...

Yes, I remember you mentioning being dyslexic a few times on this list
before, which is partly why it was only an "incidentally" at the end.
We have a pretty hot "disability and dyslexia" unit here who don't
shrink from telling me what's good and what's bad about our website!

And, just for the record re the strcmp() debate, I'm on PHP 5.2.5,
SunOS 5.10.

Not really. Date selectors are intended to make data entry easier on
the front end while allowing only valid date selections, but you can't
really rely on them.

* Most date selectors rely on Javascript, which may not be available
on the client.

* From a usability perspective, using a date selector is slower than
typing the date into a text field. Accessibility is also a concern.

* Above all, your code should still validate the correctness of input
on the server regardless of anything you are doing to make things
easier in the client. There are ways around using date selectors.

RE: [PHP] htaccess question

2011-05-23 Thread admin 
First turn your ReWriteEngine On. 
This can be done in the particular folder to allow them access to only the
one file.
You need to understand the conditions of mod_rewrite read below.

http://httpd.apache.org/docs/1.3/mod/mod_rewrite.html

OR 

you can just use the http://cooletips.de/htaccess/ from Germany.

It will take you through step by step in creating an htaccess.
I might suggest you do not use the password options because that to me is
not safe to use someone else's website when creating htaccess screen names
and passwords.

It's kind of silly if you ask me as it doesn't prevent anything since any
mildly intelligent person will just omit the [OT] and re-submit (case in
point), and it prevents other users from doing any kind of email filtering
on [OT]. It's basically punishing the sender for trying to do the right
thing. *sigh*

For most properties I use $this->property within the object because nine
times out of ten no work ever needs to be done with them. Usually they are
set by the constructor and optionally changed externally using a setter. As
long as only the class and subclasses access properties in this manner, it's
easy to change them to use an accessor later if necessary. I never access
the properties directly from unrelated classes.

When a property needs to have logic applied--either during get or set--I'll
use accessors even inside the class to ensure that work is done consistently
and avoid repetition. In some rare cases (testing framework) I use __get()
and __set() so subclasses can use $this->property but get redirected through
the accessor. This isn't possible inside the class, however, because the
magic functions are only invoked when the caller cannot directly access the
property.

What version of PHP is this available from? The web page doesn't say.
