RandID/shuffle

[czukoman20]

Ok i have a question

How would i implement this code that i wrote to use a rand id function.

The setup i would like to create is.

 

Randomly put 10 userid's in a lineup. pick the first random 5, and i display those five on a page, then when the user hits next page, it will exclude the five that it showed already, and display the last five.

 

Here is what i have written for the displaying part.

This setup below searches for the user with a userid of 1, then displays information on them

<?mysql_select_db('db215169417')
or die('Error, cannot select mysql database');
$userid_1 = 1;
$query = mysql_query("SELECT * FROM users WHERE userid_2='$userid_1'");
$values = mysql_fetch_array($query);
$nrRows = mysql_num_rows($query);
if($nrRows == 1){
   $username = $values['username'];
   echo " <img src=\"http://www.adworld-online.com/images/banners/$username"."_banner.jpg\"> <br>";
   echo ".::. Company: " . $values['companyname'] . "<br>  ";
   echo "Short info: " . $values['info'] . "<br> ";
   echo "<a href=\"http://www.adworld-online.com/submit.php?user=$username\">.::. Contact Us </a> <br />";
} else{
   echo "There is no user with that id";
}
?>

 

I have been experimenting with different random types like

<?php
session_start();
$IDs = range(1,10);// your ID array
$randID = array(5,7);
$per_page = 3;
if (isset($_SESSION['rID'])) $randID = $_SESSION['rID'];
if (count($randID) < $per_page){
shuffle($IDs);
$randID = array_merge($randID,$IDs);
$randID = array_values(array_unique($randID));
}
$curIDs = array(); 
for ($i = 0; $i < $per_page; $i++){ 
$curIDs[] = $randID[$i];
unset($randID[$i]);
}
$_SESSION['rID'] = array_values($randID);

foreach ($curIDs as $v) echo $v, "<br />\n";
?>

This code was given to me from sasa

 

That picks 3 numbers randomly and displays them, but it will display the same number twice if it is randomly picked

output looks like this

6

10

8

?>
<?php
$numbers = range(1, 10);
srand((float)microtime() * 1000000);
shuffle($numbers);
foreach ($numbers as $number) {
    echo "$number ";
}

This one is the beginning part of what i was going for. It picks 10 numbers in order, and the output looks like this

7 2 8 3 4 10 9 6 1 5

 

I would greatly appreciate people to help me out on this one, because I'm not fluent with php just yet, and I would like some help please

And please just keep the snottyness to a minimum thanks.
