send an array in a form

[rolwong]

I would like to use a POST method to send an array to another form. How can I do it?

I have tried this in form 1: (send)
echo "<input type='hidden' name='prog_array' value=$prog_array>";

In other form: (receive)
$prog_array = $HTTP_POST_VARS['prog_array];
echo count($prog_array);

But this fail...

How can I tranmist and receive an array in PHP?

Thanks.

You can use serialize and unserialize function or more occurrences of INPUT TYPE="hidden" statements.

<INPUT TYPE="hidden" NAME="array[1]" VALUE="100">
<INPUT TYPE="hidden" NAME="array[2]" VALUE="101">
<INPUT TYPE="hidden" NAME="array[3]" VALUE="102">
<INPUT TYPE="hidden" NAME="array[4]" VALUE="103">

or

echo '<INPUT TYPE="hidden" NAME="array" VALUE="'.serialize($array).'">';

and on the next page

$array = unserialize($_POST['array']);

or you can store them in session.
