Sorry, I forgot, if you have to use the $ in the getData Parameter, use:
$array = substr($array, 1);
before the return statement.

Hi
I've gone bozzeyed, so I've a simple question for you.
I open session_start() as the first thing, on each page.
I set a session variable using, for instance,
$_SESSION['ACCOUNTemail'] = $email;
The next program, when I var_dump($_SESSION), it shows an empty array.
That program does run session_start() too.
What's obviously wrong, or what's my most likely cause?
Cheers

Hi John,
What do you mean about "another program"? Is it something like...
a.php:
<?php
session_start();
$_SESSION["index"]= "value";
echo "call b <a href=\"b.php\">here</a>";
?>
b.php:
<?php
session_start();
var_dump($_SESSION);
?>
... or something else?
Try the example above, if this does not work then you should start looking
at your php.ini for session support, check if it's disabled or something.
Or maybe try using session_write_close() at the end of the scripts, they
might work (if session support is enabled).

That should work. Are you sure you're using
<?php session_start();
I forgot the () one time and it had me going for a while.
Also, try this (it should work):
======= Page 1
<?php session_start(); // page1.php
$num = isset($_SESSION ['num']) ? $_SESSION ['num'] : 0;
$num = 1;
$_SESSION ['num'] = $num;
echo($num);
?>
<form action="page1.php">
<input type="submit" value="Goto the next page">
</form>
======= Page 2
<?php session_start(); // page2.php
$num = isset($_SESSION ['num']) ? $_SESSION ['num'] : 0;
echo($num);
?>
<form action="page1.php">
<input type="submit" value="Goto the last page">
</form>
Cheers,

Thanks all, yes, it's like that, and a & b work.
The difference? I was doing
$_SESSION['index']= $myString;
instead of
$_SESSION["index"]= $myString;
Now with "s it works.
Why?
And, worryingly, I set three variables, then dump $_SESSION and it
contains three variables. I think it should still contain
$_SESSION["index"]= "value";
from the a/b test.
I'm fairly certain I'm not using any session functions to clear the
session .. best guess for the cause of the loss of that variable?
Cheers

Using double-quotes instead of single-quotes in the code you provided
should be *no* difference at all. I'm curious if there's something
else going on for you. Can you provide more complete code?
Back to your original example, calling session_start() will restart a
session, so only call that function once during a request, or make
sure to write out the session using session_write() before calling it
again.

I don't see two fields, I only see one:
$ php -a
Interactive mode enabled
<?php
class abc {
protected $x = '21345';
function __construct() {}
}
$x = new abc();
echo serialize($x);
O:3:"abc":1:{s:4:"*x";s:5:"21345";}
$y = serialize($x);
print_r(unserialize($y));
abc Object
(
[x:protected] => 21345
)
As for why they come out like that, no idea - I couldn't find any
comments on php.net about it either.

Can you please example code because I simulated the similar thing and it works fine here

public function Hello(){
echo Hello2;

(

[y:protected] => 12345

A Object
(
[x:protected] => 12345
[y:protected] => 12345
)
I think that’s perfectly fine.

Subject: [PHP] visibility + unserialization
I have a 4 year old framework that serializes objects and stores them
in the database. It is now going PHP 5-only, so I began to add
visibility to the class definitions of the serialized objects.
However, then things didn't work properly after objects stored [before
the visibility was added] were unserialized. For example, each
protected field ended up creating two fields, with one followed by
":protected".
Expected Result:
----------------------
object(Foo) {
["bar"]=>
string(0) "banana"
}
Actual Result:
----------------------
object(Foo) {
["bar:protected"]=>
string(0) ""
["bar"]=>
string(6) "banana"
}
Anybody run into this, or can explain why this might be and how I can
avoid it?
Thanks,
~Ted

Hey!
Heres my requirment, the movie clips are below the root and after the member pays for access the client want to let the user download the flick and add the sitename to the flicks filename (for example if the filename is a.avi it should download as test-a.avi)
heres the code i haev come up with so far... the download box pops up in FF but in IE it gives me the website cannot be found error
======================= code =========================
<?php
