[PHP] An important, urgent question about classes?
Hi all,
I need to learn something about classes in PHP, that I could not
understand what's going on really!?
For the following sample, what kind of class i need to create? how
can i use?
For example,
I have X students X: from 1 to infinity...
With respect to student ID of them,
And for each students, I have name,surname,addr,phone,email
etc.. informations of them
I want to create a class, such that, i can input info of students,
for each student.
And for example, when I did this for 10 students,
I want to register with "session_register" and add/remove/change
registered informarmations.
I tried to do,
but I could not understand the uses of classes clearly, so I could
not do...
Thus soem body write me small code which includes a sample class
and
adding/changing/deleting records for one student inside.
Can I register a valuable which is a class? $mydata = new
Students(); session_register("mydata"); ? is possible?
Do we have any restriction about registering a variable with respect
to its type?
thanx... best regards...

[PHP] eregi and alfa numeric characters.
Hi all,
I want a regular expression process such that,
no characters except for the followings will not be allowed.
0-9 a-z A-Z ~ @ # $ % ( ) _ - + =
[ ] { } ?
I create a web site with membership. I have a problem. Some body uses
a username GUEST and someother get's the same username (in fact not the
same, but displays as a same username, because,
second username is GUESTx where x replace with the
code ALT+231
so I want to give a sequence of characters to the user, such
that user cannot use except for this crahcters.
I wrote all the characters above...

Re: [PHP] passing parameters from one page to another
Hi,
If you want some parameters which will be pass in your site, you can
use "session"
.
for example, you have parameters, fooa, foob, fooc, ...
etc..
?
session_start();
$fooa = 1;
$foob = "sait";
$fooc = "http://www.yonlendir.com/";
//you do,
session_register("fooa");
session_register("foob");
session_register("fooc");
?
then you can use them everywhere in your site as "$fooa",
"$foob", "$fooc".
You can change it's value. you can unset with
session_unregister("fooa");
Be carefull that, your paramater is $fooa, you should register it
without $
session_register("fooa"); // No $ at the beginning
of the paramater...
And you should put session_start() at the top of the page, if
you will use these parameters in that PHP file...
Also, you can use COOKIES...! I dont prefer in general ... and do NOT
session_register a password or a credit card number, for security
reasons...
good works...

Subject: [PHP] Sizeof
variable variable arrays
Hi there guys,Who's awake today then? :) What I'm
trying to do is create variablevariable arrays and then fill these
arrays with values. The problem Ihave though is that the values don't
appear to be getting stored - asfollowing the assignment I have
outputted a 'sizeof' command whichalways outputs 0.Here's a
snippet of the code. Any ideas guys???//store
children page_IDs into array for each parent$str_array = "menu_array_"
. $current_parent_page_ID;$$str_array = array();for
($child_cnt = 0; $child_cnt $number_children;
$child_cnt++){$db_help_structure-next_record();//get
page_ID value$page_ID =
$db_help_structure-return_single_result('page_ID');//$page_ID
is now setecho "storing in $str_array position $child_cnt:" .
$page_ID ."br";$$str_array[$child_cnt] = $page_ID;echo
"size:" . sizeof($$str_array) .
"br";}Email:
