RE: [PHP] advise on simplfying session usage
When I have many calls to $_SESSION I do:
$s = &$_SESSION;
$s['foo'] = 'bar';
echo $s['foo']; //bar

Subject: [PHP] advise on simplfying session usage
Again, coming from ASP background, I'm trying to minimize the typing for
most needed functionalities..
in asp, to set a session var, you go <%session("age")=90%> and to output it,
you just go <%=session("age")%>
in php, you've got to _SESSION['age']=90. that's a lot of keyboarding, lots
of double key strokes and the entire word session has to be uppercase.
of course, if you use an IDE and you get fast at it, this may not be an
issue but I wanted to simplify it anyway.
so the plan is this
To achieve this; I wrote this preliminary function;
function _s($var,$val = "r4r53d323,9e809023890j832e@14fdsffdd")
{
if ($val == "r4r53d323,9e809023890j832e@14fdsffdd")
{return $_SESSION[$var];}
else
{$_SESSION[$var] = $val;}
}
Now, what's that number you ask!... it's just a value which I figured I
would never end up in a real app.
It's just a way for me to use default argument of the function so I can call
_s function with 1 or 2 arguments.
Can this be done a better way? How do you use _s function with 1 or 2
arguments so in 1 arg mode, you can use it as a set, and in 2 arg mode, you
use it as a way to return val.
Is func_get_args route the only way? performance wise which one would
better?

[PHP] help in reversing an array
Hi all and Merry Christmas!! I am having some trouble reversing the order of an array. I have this array: $array[0]='Socket A'; $array[1]='Single processor'; $array[2]='Motherboards'; $array[3]='Hardware'; and I want to do a "simple" reverse of the content like this: $array[0]='Hardware'; $array[1]='Motherboards'; $array[2]='Single processor'; $array[3]='Socket A'; Which function amongst the available should I use? Thank you. Pedro Almeida.

Can I do any session handling before calling header("Location: $url"); ?

header("Location: $url");
which, by the way, makes a hell of a lot more sense. It's just an HTTP
response header like any other response header and it is called
Location, not Redirect.

RE: [PHP] How to argue with ASP people...
I used response.redirect in asp to avoid form re-submit, so I can have form
handling functions and other related functions on the same file.
new_customer_form.php :
< form action="form_results.php" >
Customer fills form and hits submit button.
form_results.php :
function validate_form_data(){
if true show_results();
}
function show_results() {...}
Now customer is on results page in show_results().
If he hits the Refresh button or Back then Forward buttons in he will be
prompt to resubmit the form data or cancel.
If I add header("Location: form_results.php") inside function
validate_form_data() instead of calling function show_results() I can avoid
this behaviour.
I don't know if this is the right procedure, i am learning as I develop.
This was a workaround for shopping cart and customer area form handling form
handling code. Probably I'm doing it all wrong :)
And Robby thanks for the ob_start() tip!
I apologise for my bad English writing.

Yeah, sure. You just can't have any output before you redirect with a
Location header (unless you use output buffering as a workaround).
This is basic HTTP and ASP has to play by the same rules. If you can
have output before Response.Redirect, then ASP is just doing the
buffering for you before it sends a Location header.

RE: [PHP] How to argue with ASP people...
-Mensagem original- De: John Holmes This is a workaround, really. Your code should be structured so that you can decide if you need to perform a redirect before any output is sent to the browser. If you're going to send them to another page, why would you have any output anyhow? Using templates sometimes forces you to do this, as you perform all of your business logic / PHP code before hand and then display the appropriate templates. If you need to send the user to another page, it's easy to do so at any point before your templates are shown. ---John Holmes... Yes you are right, that is what I am doing now, taking all validation / verification functions that do not output html to top, after session handling. This is my first php application as I am migrating from asp and trying to "mirror" my application in php. I have separate php files to handle different "areas" of the site and like you say I use header+footer sort of template. Thanks. Happy New Year!

[PHP] help avoid multiple login
Greetings I'm having some trouble on a members online script. I use a php script to track member login to avoid multiple logins on different ips etc. When a logged member closes the browser window I can't delete the table entry because I will not have access to some sort of "Session_OnEnd" action on hosting. Is there a workaround for this? I'm using PHP 5.0.4 and IIS on win XP. Thanks in advance. Pedro. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

what exactly do you mean by that last sentence? I don't quite follow it.

I mean if I knew all active session id's I could compare them to the
members_online table.
An example in pseudo code:
// Member logs in, store session id, login datetime, last visit datetime:
INSERT INTO members_online
// Get active session ids from table:
php code
// Compare active session ids with table sessions:
for ($i=0; $i < table rows; $i++){
if ( !isset( session id from member $i )) {
DELETE member from table
}
}

I already use a class to perform this task. The problem is if a member
closes the browser windows and then tries to login again before the
specified timeout.
Does Apache have a function like asp Session_OnStart, Session_OnEnd ?
I am using IIS and PHP 5.0.4
Thanks in advance.
Pedro.
