The easy way to do this is with sessions; be it strings, numbers,
arrays, whatever.
<?php
session_start();
$_SESSION['myarray']['one'] = 1;
$_SESSION['myarray']['two'] = 2;
$_SESSION['myarray']['three'] = 3;
$_SESSION['myarray']['four'] = 4;
$_SESSION['myarray']['five'] = 5;
// Now you have array $_SESSION['myarray'] with your values in it
?>
And then any page with session_start() should load all the values
stored in $_SESSION on subsequent pages. Much easier than messing
around with forms and submitting from page to page. Since $_SESSION
itself is an array, you can load it up with anything you want -
strings, numbers, other arrays, other nested arrays, etc.
<?php
$_SESSION['blah'] = 'foo';
$_SESSION['count'] = 5;
$_SESSION['myarray']['five']++; // five is now 6
?>
