// This is Javascript, not PHP!
function js_array_to_php_array (a)
// This converts a javascript array to a string in PHP serialized format.
// This is useful for passing arrays to PHP. On the PHP side you can
// unserialize this string from a cookie or request variable. For example,
// assuming you used javascript to set a cookie called "php_array"
// to the value of a javascript array then you can restore the cookie
// from PHP like this:
// <?php
// session_start();
// $my_array = unserialize(urldecode(stripslashes($_COOKIE['php_array'])));
// print_r ($my_array);
// ?>
// This automatically converts both keys and values to strings.
// The return string is not URL escaped, so you must call the
// Javascript "escape()" function before you pass this string to PHP.
