Passing arrays between urls 2

[NVSbe]

In call.php, I have three arrays, data1, data2 and data3. I'd like to pass them to script.php in the form of:
script.php?data1=$data1&data2=$data2&data3=$data3

but if I do this, and use a $_GET to fetch the results, it appears all that has been passed is the word "Array". Is that normal?

It is the expected behaviour, yes. You would probably want to [tt]serialize[/tt]() the arrays and [tt]unserialize[/tt]() them in [tt]script.php[/tt].

I strongly suggest that you use the session capabilities of PHP.
All you need is start a session in both scripts using the start_session();

# call.php
start_session();
$myArray[] = "data1";
$myArray[] = "data2";
$_SESSION['myArray'] = $myArray;
# etc....

# script.php
start_session();
$myArray = $_SESSION['myArray'];

This way you need not worry about the encoding etc. The data is stored on the server between accesses and there is no restriciton to size. The only thing passed to the browser is a cookie with the unique session ID.

If you really want to pass it in the URL, you just write a URL query string out with a foreach loop. If you just use the print command it will only say 'Array' since arrays can't be output using the print command.

Thank you so very much... I'm rather new to php, you see, and the amount of information out there is just overwhelming

About sessions. I have heard about them, but since this is my second day in php, I have yet to use them. It didn't seem convenient to me in this example, because the script.php url is a script that uses the data in the arrays to make a bar graph with the JPGraph package.. like this:

<?php

$data1 = array(1,2,3,4);
$data2 = array(1,2,3,4);
$data3 = array(1,2,3,4);

$sdata1 = serialize($data1);
$sdata2 = serialize($data2);
$sdata3 = serialize($data3);

?>

<img src=<?php echo &quot;\&quot;script.php?data1=&quot;. $sdata1. &quot;&data2=&quot;. $sdata2. &quot;&data3=&quot;. $sdata3. &quot;\&quot;&quot; ?>>

Of course, in the future, I'll be looking into sessions.
