>Description:
	
PHP passes variable from a form via HTTP GET (in URL) or POST
variables (in HTTP body).  The PHP form processor never sees those
variables. 

This broke when I upgraded to the security fix for mod_php 4.2.2.


>How-To-Repeat:

A simple form, form.html:

<form action="form-vars.php">
<input name="var1" value="ThisIsVar1">
<input name="var2" value="ThisIsVar2">
<input type="submit">
</form>

A simple form processor, form-vars.php

<?php
echo "<BR>argc=$argc argv0=$argv[0] argv1=$argv[1] argv2=$argv[2]";
echo "<BR>var1=$var1 var2=$var2";
echo "<HR>";
phpinfo();
?>

Point web browser at form, hit SUBMIT, see output:

argc= argv0= argv1= argv2=
var1= var2=

It doesn't even have a count for variables.

>Fix:

Unknown.
