Hi, I installed PHP 4.2.3 on a Windows NT workstation with Xitami Web Server 2.4d9.
I have a simple html page with a form like this:

<FORM NAME="myname" METHOD="POST" ACTION="test.php">
<INPUT TYPE=TEXT NAME="myfield" SIZE=20>
<INPUT TYPE=submit>
</FORM>

and a simple php file (test.php) like this:

<HTML>
<BODY>
<?php 
   echo "Your field is: ";
   echo $myfield;
?>
</BODY>
</HTML>

When I use the submit the form, PHP executes test.php
and give my this page:

Your field is:
Notice: Undefined variable: myfield in C:\Xitami\webpages\test.php on line 5

If I unistall PHP 4.2.3 and install PHP 4.1.1, everything works fine and I got what I wrote inside myfield.

I don't know if this is a bug or a security problem.
