Random Multiple

[Blade Maker]

Is there anyway you can do this:

rand(1,3,6)

for the random function?

Please explain in details thanks.

use an array http://php.net/manual/en/function.array-rand.php

Thanks I hope it works.

quick example (in answer to the pm)

<?php
$array = array(1,3,6);
$rand_keys = array_rand(array_flip($array), 1);
echo $rand_keys;
?>

i am sure there is a better way but that would work :)

Its kinda good, but I need to put a variable in that.

The variable calls numbers from the database, and I want the numbers to be put into the array and then randomly selected.

Am I on the right track?

Sources forom Kirby:

<?php

include "globals.php";


$array = array($_POST['hidden']);
$rand_keys = array_rand(array_flip($array), 1);

echo $rand_keys;



$get1 = mysql_query("SELECT * FROM `inventory` WHERE inv_userid=1 ORDER BY inv_itemid DESC LIMIT 9999");



?>

<form method='POST' >

<?php
while ($row = mysql_fetch_assoc($get1)) { ?>

<input type='hidden' name='hidden' value='<?php echo $row['inv_itemid'];?>' /><?php } ?></form>

 

basically what he want is being able to pick 1 item out of the inventory. This is how I would do it:

include "globals.php";
// Retreive how many items the user have and then get a row number randomly
$r=mysql_query("select floor(count(*)*rand()) from inventory where inv_userid=1");
$row=mysql_fetch_row($r);
$nb=$row[0];

$r=mysql_query("select * from inventory where inv_userid=1 limit $nb,1");
$row=mysql_fetch_assoc($r);
// ... you must then continue
