arrays sent in header

[Anon]

Hello,

I'm sending an array over using a header function like so: -

header("Location: confirm.php?member=$member");

$member is an array in the calling script. When $member gets to the called program it appears to just be string 'Array' as opposed to an actual array.

Does anyone have any idea why this would be and how to get a value sent across this way?

It seems everthing is OK. BEcause in any condition if you want to 'echo out' and array, you only will see 'Array' on the screen. I mean that array is succesfully received by the other page.
Your only work is access the array by using its indexes such as
<?
echo $member; //it only writes 'array'
//you should use
echo $member[0];
echo $member[1];
//if you don't know the size of array you can use foreach or count
foreach($member as $mem)
{
echo $mem;
}
?>

Sorry, maybe I should have included more in my last post.....

I had been using foreach to begin with in the recieving program but was getting a 'Warning: invalid argument supplied for foreach' error.

I then tried to access each element in turn but got the various letters of the word 'Array' back. E.g. echo $member[4] brings back 'y'

hmm. got it. I think it seems that unfortunately, if you want to pass the array, you should pass the values by passing each element.
<?
//I want to pass the $array
$array_str="";
foreach($array as $element)
{
$array_str.="array[]=$element&";
}
$array_str=substr($array_str,0,-1);
header("Location:d.php?$array_str");
?>

I am sorry, ý can't think about anyother solution.
Good luck

Thanks,

I wonder whether it is possible to make the header function call a script as if it had been POST'd then it may be possible to access the variables using $HTTP_POST_VARS

It's a lot easier to serialize the array first
and pass it as a string to the next page and then
unserialize and use the array!
You need to use urlencode/urldecode!
For more info, read here:
http://www.php.net/manual/en/function.unserialize.php
http://www.php.net/manual/en/function.serialize.php

And some examples:

page 1:
<?php
$member = array("Php", "JavaScript", "Linux", "Java");
$member_serialized = serialize($member);
header("Location: confirm.php?member_serialized=$member_serialized");
?>

page 2 (confirm.php):
<?php
if (isset($member_serialized))
{
$member = unserialize(stripslashes($member_serialized));
}
reset($member);
while (list ($key, $value) = each ($member))
{
echo 'member['.$key.'] => "'.$value.'"'."<BR>";
}
?>
