No.
You'll just get Array back.
You can do a few things:
?php
foreach($attend_ary_save as $k1 = $v1){
foreach($v1 as $k2 = $v2){
?input type=hidden name=attend_ary_save[?php echo $k1?][?php
echo $k2?] value=?php echo $v2? /?php
}
}
?
Actually, you should wrap htmlentities() around each value being echo-ed
out.
Another option is to http://php.net/serialize the data before you send it to
HTML, and then (duh) unserialize it when it comes back.
Or, be REALLY smart, and use session_start() and just put the array in
$_SESSION and don't send data back-n-forth over HTTP, which is A) expensive,
and B) subject to user tampering, and C) inefficient.
Actually, A and C technically depend on your bandwidth versus hard drive
speed, or wherever you store you session data, so, in theory, it could be
cheaper or more efficient to use HTTP... But I sure doubt it in any real
world hardware setup.
PS Just FYI, internally, PHP's session data is just serialized the same way
you'd do it for HTTP.
