Hi
I need a way to change a page on every refresh
This is the code I have (the part that matters)

<div id="body">
<?php include('1.php'); ?>
<?php include('2.php'); ?>
<?php include('3.php'); ?>
<?php include('4.php'); ?>
<?php include('5.php'); ?>
</div>

I need to either randomize or rotate the order of the php files on every refresh, preferably rotate.

so 1-2-3-4-5 refresh 2-3-4-5-1 and so on (or randomize)
what's the best way to do it?
I don't mind completely changing the code, the order can be randomized but all must appear without repetition.
Thanks

If you're posting your codes, use [code] tags!

<?php
echo '<div id="body">';

$input = array("1.php", "2.php", "3.php", "4.php", "5.php");
$rand_keys = array_rand($input, sizeof($input));
for($i = 0; $i < sizeof($input); $i++) {
	include($input[$rand_keys[$i]]);
}

echo '</div>'
?>

Or

<?php
echo '<div id="body">';

$input = array("1.php", "2.php", "3.php", "4.php", "5.php");
shuffle($input);
foreach ($input as $files) {
    include($files);
}

echo '</div>'
?>

Note: This the second method assigns new keys to the elements in array . It will remove any existing keys that may have been assigned, rather than just reordering the keys. Although that might be a drawback, it is more efficient - but if is a concern, use the first method.


Don't worry about the E-Gold :)

Isn't there an mt_rand() function that just accepts the upper and lower bounds as parameters? You could just do that, then concatenate it with the .php extension.

mt_rand will return a single value between the upper and lower bound. If you do this in a loop, there is no guarantee all the numbers will be unique without repetition.

Oh - that's pretty clever. I suppose it's useful if you just wanted to load one php file out of the lot.

Indeed.
