Passing array as value of a variable (PHP & HTML)

I am developing a web site which requires a set og unique values be
transferred between pages and server many times. There fore i decided
to put the values in an array so that only one reference to the array
is needed ratherthan idividual reference. The situation is like this:

When the page is loaded based on the user input say 6 values are
created like character1="tom", character2="jerry", Character3="micky",
Character4="donald", character5="cat", character6="rat". This to be
preserved for two or three further pages to be loaded based on further
user input. One solution is to create <input>tags with names
Character1, character2, ............character6 and assign values to
each of them. But when the list is enlarged say to 75 values it is
unweildy. So I found that when the page is first created an array is
created like $character=array('tom', 'jerry' , 'micky', 'donald',
'cat', 'dog')and can be assigned to a single input tag. Is it possible
to such a tag like "<input type="hidden" value=$character>". Or is
there any better alternative to this ? Any help is verymuch
appreciated.

regards,
Raju V.K.

I believe you have two options:

1) Create one hidden field per character and use square brackets in the
name:

<input name="character[0]" type="hidden"
value="<?=htmlspecialchars($character[0])?>"><input name="character[1]"
type="hidden"
value="<?=htmlspecialchars($character[1])?>">

2) Use a string and the implode and explode:

<? $character=explode('|', $_GET['character']); ?>
<input name="character" type="hidden"
value="<?=htmlspecialchars(implode('|', $character))?>">

where '|' is a character not used within character names.

Any reason for not using sessions?

http://php.net/session

Or

3) use a single html field & serialize the array (and unserialize on
receipt).

Or

4) keep the array in a session variable and pass the session handle through
the browser.

One word of caution re: sessions

The user is perfectly capable of opening multiple pages from the same
website. Sessions are used for page-independent parameters (e.g. user
name/password, ...). If your info is page-specific don’t use
sessions, or if you do, make sure untargeted pages don’t use it by
mistake. You can do so by adding the target url info to the session
content.
