Description:
------------
Red Hat 7.3/Apache 2.0/PHP 4.3.3.

If I select multiple selections on a select box,
with an array name,
with a form method of post

I do not get the array of selected values I expect.

If one option is selected it works fine.  
If I use a method of get it works fine.

Here is what phpinfo.php displays when I select 1 and 2:

_REQUEST["param"]	

Array
(
    [0] => 1
    [1] => 2param[]=1
    [2] => 2
)

_POST["param"]	

Array
(
    [0] => 1
    [1] => 2param[]=1
    [2] => 2
)

Reproduce code:
---------------
<html>
<body>
<form method=post action=phpinfo.php>
<select name="param[]" multiple size=6>
<option value=0>0</option>
<option value=1>1</option>
<option value=2>2</option>
<option value=3>3</option>
<option value=4>4</option>
<option value=5>5</option>
<option value=6>6</option>
</select>
<input type=submit>
</form>
</body>
</html>

------------------

phpinfo.php
<?
phpinfo();
?>

Expected result:
----------------
_REQUEST["param"]	

Array
(
    [0] => 1
    [1] => 2
)

_POST["param"]	

Array
(
    [0] => 1
    [1] => 2
)

Works fine for me. How did you configure PHP? 
How did you configure PHP for Apache2?

Add this line to your test script:

echo $HTTP_RAW_POST_DATA;

And set "always_populate_raw_post_data" php.ini option to 'On'. Then post the result here.

Here is what the raw post data looks like:

param%5B%5D=1&param%5B%5D=2param%5B%5D=1&param%5B%5D=2

Here is my configure info:  Need more?

Additional info: 
  Things also work fine if my action is a perl cgi-bin script:

content_length = 27
stdin = param%5B%5D=1&param%5B%5D=2

Instead of using --with-apache2filter, use --with-apxs2, which enables the apache2handler version. Please let us know if that works.

See bug #18648.

That's caused by the configuration error.
 [2003-09-23 23:22 UTC] fmuller at cisco dot com 
Yes, I agree this bug is bogus.  I was able to reconfigure httpd.conf as suggested in 18648, and fix the problem.

I simply commented out the following as suggested from the 
Redhat sample httpd.conf file, and restarted apache.

#<Files *.php>
#    SetOutputFilter PHP
#    SetInputFilter PHP
#    LimitRequestBody 524288
