You can use implode _or_ serialize for this.
$arr = array('a','b','c','d');
$vars1 = implode('|', $arr); // a|b|c|d
$vars2 = serialize($arr); // try it :)
And send one of the above strings through your
"hidden" form element.
Then upon use, either explode or unserialize it.
Also consider using urlencode() in addition to
one of the above methods. Anyway:
$arr1 = explode('|', $vars1);
$arr2 = unserialize($vars2);
Ah yes, our arrays are back :)
