Built 4.2.0RC4 with Apache 2.0.35
Build files below.

Testing an existing site I noticed that I was dropping parameters passed between pages.

Using an anchor like: 
<a href="somepage.php?valuea=something">Click me</a>

An code in the other page like:
    echo "value=:".$valuea.":";

Is not return the expected output (value=:something:)
Instead I get (value=::)

It looks like the name/value pair is being lost.
I have attached two test pages. These work in Apache 1.3.20/PHP 4.1.2.

There seem to be no errors in the apache logs.
127.0.0.1 - - [17/Apr/2002:09:02:30 -0400] "GET /php/atest.php HTTP/1.1" 200 117 "-" "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.9) Gecko/20020311"

The bug system is not the appropriate forum for asking support
questions. For a list of a range of more appropriate places to ask
for help using PHP, please visit http://www.php.net/support.php

Hint: use $_GET['valuea'] or set register_globals to on

While I agree these might work (thought they don't) this is not a support question, this is a bug!

I am working with Apache 2.0.35 and PHP 4.2.0 RC4 compiled as a DSO. The behaviour I am describing occurs as described. The behaviour is different to that I get with the same modules under my production systems using Apache 1.3.20/PHP 4.1.2.

The php.ini file has register_globals set on. (the default it would seem) (I am assuming it is reading the version in /etc/php.ini)

The $_GET does no better than the use of global variables. 

Have I tripped up over some compile option that is amusing the gods? 

Alistair...

Try a print_r($_GET); does it show anything?
If it does show the variables, then your problem is that PHP reads /usr/local/lib/php.ini (default) and not /etc/php.ini (only default with special ./configure option). See the phpinfo(); output for more.
 [2002-04-17 15:43 UTC] alistair at maclean-nj dot com 
Copied over php.ini-recommended to /usr/local/lib and renamed to php.ini.

Edited register_globals (as it is defaulted to Off in this file) and restarted.

App now seems to function as expected.

Was the php.ini meant to be copied over by me, or by the "make install"?

By you, otherwise every recompile or upgrade would
clobber your php.ini file :)
