When working with forms, I use this code to display all of the variable names
and their values:
DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

<HTML>
<HEAD>
<TITLE>Show Vars</TITLE>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

<BODY>
<?php
$Vars = "HTTP_${REQUEST_METHOD}_VARS";
echo "<br>
<b>$HTTP_REFERER</b>
<br><br>
<b>$Vars</b>
<br><br>
<table border>
<tr>
<th>Index</th<th>Element</th>
</tr>";
while (list($IndexValue, $ElementContents) = each(${${Vars}}))
{
echo "<tr>
<td>$IndexValue</td><td align=right>$ElementContents</td>
</tr>";
}
echo "</table>";
?>
</BODY>
</HTML>
