This may be that stupid answer, but I see what appears to be two problems.
1 - $result is not declared globally in your function header, so hence
it's undefined, hence all of its methods are.
2 - you have a couple indices wrapped in curly braces, not parens. Is
that some new kind of syntax I'm not aware of?

Perhaps he could share all relevant code, since at this time we are mostly
guessing.
Declaration/assignment of a lot of variables isn't included in the snippets.

[PHP] A stupid question about classes
Hello everyone,
Just a basic question.
I have my class starting like this:
Class OireMail {
// these are required
public $smtp_server=;
public $domain=;
public $from=;
public $login=;
public $pass=;
And then go the function themselves.
I was told that it's better to put the initial variables in the
__construct() function. What are the advantages of doing that and if I
need to do it, how would I call the class from another file then?
Thanks!

The advantages of initializing the variables in __construct() is that
whenever an object of the class is created, the variables have the
values you expect.
If you don't put them in __construct(), you will have to create another
method which will have to be called after you have created the object
using the new operator.
Ultimately its the same thing, __construct() is called automatically,
only that's the difference.

So could you illustrate a bit the __construct() function, please?
Should I pass those variables as parameters of that function? And what

One other thing is you won't be able to start a session if headers
have been sent. It is a good idea to use output buffering to help
aid with this.
no it's not a good idea to use output bufferin to 'help aid' this.
instead write code that is logically structured so that the

generated.
to avoid spurious output of whitespace avoid including the trailing

If headers have been sent you'll get a nasty warning.
if (headers_sent()) {

}
use code to avoid warnings.
It can be a php.ini setting or you can simply call ob_start() on
the first line of your script.
I agree with you that it is ideal to do what you're saying but it
isn't always 100% practical. Sometimes the stuff we work on is
handed down and in our purist world we'd like to change it, but
can't. So I think that you should recommend best practices for
future creations, but blindly shooting down all alternatives isn't
right. My solution would get the job done rather than the OP
refactoring the pages and not getting paid for it. It would work
and over time things could be tidied up on future revisions over time.
still, it's not a good idea because that implies a concept that you
are wanting to apply. you don't want to use output buffering if you can help
it.
output buffering to overcome output being created before headers are
[conditionally] sent in badly written code is a viable hack given
certain budgetary and/or time constraints.
what I'm saying is it's a viable solution to a immediate problem for
which you don't have the time/money to fix properly - it's more than
fine to enlighted the OP as such, I just don't think calling it a good
idea is the right thing to do - it gives the impression that your
giving it the seal-of-good-coding-practice-approval, and the OP might
just take your word for it.
Also, if you do what you've said and created your logic 100%
perfectly, there should never be any use for headers_sent(), right?
Headers shouldn't have been sent until you've specifically sent them.
true, and they are not - but if you want to be sure to avoid cruft in
the output and/or shit in the logs you program defensively for those
occasions where somebody [else?] makes a mistake of some kind.
Fair enough, you win! :)

If headers have been sent you'll get a nasty warning.

http://us3.php.net/session_id
is what you are looking for.
Look at the notes for the Return Values section
session_id() returns the session id for the current session or the
empty string () if there is no current session (no current session id
exists).
So, something like this will do.
?php
$sid = session_id();
if ( $sid == '' ) {
// No session started yet.
} else {
// Session has been started.
}
?

Any tip is greatly appreciated. Regards, Shelley Hey Shelley, maybe I can help you understand Sessions. When you start a Sessions PHP creates a Session ID. This is then used to create/Store information in a file or in a database. The configuration of this is in your php.ini file. If this file you can change where the session is saved as well as other options. A simple way to use Sessions is with cookies with the session.use_cookie = 1 in the php.ini file. However, if the client doesn't allow cookies there is a second way; session.use_trans_sid = 0 there are a few problems however, it creates a security risk. Anyway, I hope this opens a little on how sessions works.

RE: [PHP] a stupid question
Your test that works suggests that the function is echoing its results,
and not actually returning its results. To return its results the function
needs to end with
Function aFunction() {
do something;
Return $resultstring; // very last statement executed in function.
}
This should allow
Echo some string value.aFunction().another string value;
To work,
Good luck,

when you are working with classes and objects in php, and you are coding
inside a class, you must use the $this variable to access the members of the

Square brackets are more common but both are valid array syntax. There may

Liam, when you want to post a new message to the list don't just hit the
reply button and change the subject. If you do that you message appears
in the thread of the message you replied to.
It really messes things up for people who follow message threads. And
worse you might not get any answers to your question since your question
has nothing to do with the thread your posting now becomes part of.
To answer you question though:
I don't know of any short-hand for what you want to do. But this should
work.
if ( ($idx != 1) ($idx == 4) ($idx == 9) ) {
echo$results;
}
You could also look into using a regexp.

[PHP] ... [PHP] Stupid question alert
Thanks for everyone's comments. If I understand what you are saying it should be possible to fill the content of a layer by issuing some sort of server include command.. (?) So, for example, rather than have a something that looks like this: div id=haiti style=position:absolute; left:752px; top:321px; width:166px; height:162px; z-index:14; visibility: hidden table width=166 border=0 cellpadding=0 cellspacing=0 tr td img src=Atlas/images/photolayer_11.gif width=81 height=55/td td img src=Atlas/images/photolayer_12.gif width=85 height=55/td /tr tr td img src=Atlas/images/photolayer_14.gif width=81 height=53/td td img src=Atlas/images/photolayer_15.gif width=85 height=53/td /tr tr td img src=Atlas/haiti_17.gif width=81 height=55/td td img src=Atlas/haiti_18.gif width=85 height=55/td /tr /table /div It should be possible to have some code that gives the layer position but rather than then having all the other code describing the layer contents, have some sort of php command that says 'get the contents from file xxx.php'. If this is the case what should I be learning about to make this happen? Thanks again, Tim (standing on the shoulders of giants) Your question is not stupid - it's just uninformed, and that's easily understandable if you never used PHP. The concept is dynamically creating the page SERVER-SIDE. That is, use some databases or some nifty code to dynamically build a page using specific parameters. Unforunately for you, this means that all the fun ends on the server side. Once PHP ends its job, Apache takes over and serves the content generated by PHP as it would serve any regular file. What you actually pass to the client is dead information - it's not dynamic unless you echo some JavaScript code or something similar from PHP (which is the same as writing the respective code in a regular file, unless you create some custom parameters in JavaScript based on some other parameters you pass to PHP). Hope my explanation makes sense... ;-) Bogdan tim at 10Kv wrote: Hi, first of all apologise to the list this is a very basic question for you I¹m sure. I have tried to find an answer on the web but the problem is knowing HOW to ask the question and I hoping you can provide me with a starting point. Anyway.. I design a lot of graphic intensive pages which rely heavily on layers that contain images, mouseovers and image swaps. The trouble is, when there are more than a couple of these layers on a page the code gets long and over complicated. For example, if I have a page which on one side contains an image map with 5 clickable points that shows one of 5 possible layers on the other side of the page (each with different content) this is automatically a page with lots of code which is slow to load especially if the page already has a layer based navigation bar! My question is: is there a way to use a language like php to make this process easier? For example populate the layers from a different file rather than have all the code on the same page and perhaps slim the page down a little or is this missing the point of what a language like php is about. Thanks for your help and my apologies if this is the worst question of the week.
