Pick 5 random entrys

[Krustov]

What is wrong with this php code ? .

(it works fine - but something that just works isnt good enough for this
newsgroup is it)

<?php

$loopy=1; $kon="repo"; $spock=0;

while ($kon=="repo")
{
$khan=(rand()%$ chekov); $khan=$khan+1;
if ($kirk[$khan]=="") {$spock=$spock+ 1; $kirk[$spock]=$khan;}
if ($spock>55) {break;}
if ($loopy>222) {$kon="break";}
$loopy=$loopy+1 ;
}

sort($kirk); $kirk=array_key s(array_flip($k irk));

$loopy=0;
while ($loopy<5)
{
$bones=$kirk[$loopy];
if ($bones<>"") {include('displ ay_entry.php'); }
$loopy=$loopy+1 ;
}

?>

Krusty, one day soon your code will be used by all the great teaching
establishments of the world. Here is example code to take the breath
away. Clarity, beauty, functionality, conciseness - out the window
with you! Here are perfect examples of how not to write code.

Never in the field of computer programming has so much crap been
written by so few.

P.S. if you wrote your code properly you would see the problem on the
6th line after <?php.

Why don't you just tell us what it's supposed to do? If you just need
five random numbers from a range you've got waaay too much code.

I needed something to fill up the guestbook.php page and displaying some
random guestbook entrys was the quick fix solution i came up with .

As the (latest entrys) button is right next to it - obviously its best
to display the oldest of the 5 random entrys first .

Can you post 1 or 2 lines of 'magic wand' code to do the same job ? .

if you have $n entries, how about doing something like
<?php
$indices = range(0, $n-1);
shuffle($indice s);
$indices = array_splice($i ndices, 5);
rsort($indices) ;
?>

Granted, it isn't fast, but it's easy to read/maintain and the speed
difference will be negligible if $n isn't very high.

Sorry about my earlier post, I thought you were making a joke.

Yep.

Let's say you have entries numbered from 0 to $n

$rand_entries = array_rand(rang e(0, $n), 5);
//$rand_entries is now an array containing 5 random numbers between 0
and $n

Hey look - a UK lottery ball picker!

asort($ar=array _rand(range(1, 49), 6));
echo implode(", ", $ar);

That must be where the magic wand comes in eh! :-)

Looking at it again, if $bones is the variable to get the entry

$rand_entries = array_rand(rang e(0, $n), 5);
foreach($rand_e ntries as $bones){
include('displa y_entry.php');
}
