Bug description: Array of widgets problem when array is zero based

I have recreated this problem in both PHP 3.0.16 and 4.0 RC2. When using an array of checkboxes that had a zero based value, the following script had variable and erratic results. When the commented out for{} construct that start at 1 are added back and comment out the for{} that uses 0, it works fine. After reviewing the Open Bug Report list, I have found that Bug ID #4433 may be having the same problem.

Script to recreate problem:
----------------------------

<?php

  echo "<form action='$PHP_SELF' method='post'>\n";

                $NumChecks = count($chkArray);
                echo "The number of Checks in the array is: $NumChecks<BR>\n";
                if ($NumChecks > 0)
                {
                        for ($y=0; $y<$NumChecks; ++$y)
                        //for ($y=1; $y<=10; ++$y)
                        {
                                echo "\$chkArray[$y] is $chkArray[$y]<BR>\n";
                        }
                }
                else
                {
                        echo "\$chkArray is empty<BR>\n";
                }

                $NumHide = count($HideArray);
                echo "The number of Hidden items in the array is: $NumHide<BR>\n";
                If ($NumHide > 0)
                {
                        for ($y=0; $y<$NumHide; ++$y)
                        //for ($y=1; $y<=$NumHide; ++$y)
                        {
                                echo "\$HideArray[$y] is $HideArray[$y] <br>\n";
                        }
                }
                else
                {
                        echo "\$HideArray is empty<BR>\n";
                }

                //for( $x=1; $x<=10; ++$x)
                for( $x=0; $x<10; ++$x)
                {

                        $strChecked = "";
                        if ( $chkArray[$x] == $x ) { $strChecked = " checked "; }

                        $HideVal = $x+100;
      
                        echo "<input type='checkbox' name='chkArray[$x]' value=$x".$strChecked."><br>\n";
                        echo "<input type='hidden' name='HideArray[$x]' value=$HideVal>\n";
                }

                echo "<input type='submit' name='GetData' value='Submit'>";

  echo "</form>";
