Complied as cgi binary.
When implode is passed an array with an element that contains an array the contents of the contained array  is lost.. eg.

 <?php

$tmp=  array ( array(   "x"=>"first_item",
                        "y"=>"second_Item",
                        "z"=>"third_item"
                        )
                );
$cpy=$tmp;

// echo "size at start ".sizeof($tmp[0])."<BR>";
echo "1st implode call: ".implode($cpy,"+")."<BR>";
echo "2nd implode call: ".implode($tmp[0],"+")."<BR>";
echo "size at end ".sizeof($tmp[0])."<BR>";  
?>
             
gives the following output:
==============================
1st implode call: Array

Warning: Bad arguments to implode() in /usr/local/apache/htdocs/Widget/test.php on line 12
2nd implode call: 
size at end 1
==============================

However uncommenting the first 'echo sizeof()' line gives the following result;
==============================
size at start 3
1st implode call: Array
2nd implode call: first_item+second_Item+third_item
size at end 3
==============================

something not being initialised in implode() ?
