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));

You left out how to sort them into the lowest number first - and you
left out how to display the 5 entrys .

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

As I've no idea how you are storing your entries that's not really
possible is it?

I'd be storing them in a database in which case I'd simply pass the
values into a query.

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');
}

What about $ds9['sisko']? You have your entries stored somewhere, either
in a $ds9['dax'] or in a $ds9['odo'] so that they can be $ds9['beamed'].
Each entry should have its own $ds9['rank'].

Then just take the $ds9['defiant'], pick $ds9['quark'] out of the
$ds9['bar'] and load those $ds9['founders'] from wherever they're
stored. $ds9['garak'] might also offer some helpful tricks.

Micha

PS:

$ds9 = array_map('str_ rot13', array(
'sisko' ='EGSZ',
'dax' ='QO',
'odo' ='syng svyr',
'quark' ='svir enaqbz ahzoref',
'garak' ='Neenl fbegvat shapgvbaf',
'founders' ='negvpyrf',
'defiant' ='uvturfg ahzore',
'bar' ='enatr',
'rank' ='havdhr ahzrevp VQ',
'beamed' ='ernq vagb na neenl'
));

It's $ds9['odo'] or more likely multiple $ds9['odo'] Krusty doesn't do
$ds9['dax']

>Each entry should have its own $ds9['rank'].

I'm guessing there will be a separate $ds9['odo'] for each entry.

What's with that, and why is $spock a number? Why not name your
variables for what they really are?

$khan=(rand()%$ chekov); $khan=$khan+1;

$some_integer++ is available and widely used. Where is $checkov?

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

None of that makes any sense to me. Why all these specific values for
variables?

while ($loopy<5)

$loopy=$loopy+1 ;

None of this makes any sense. Nobody has a magick wand, what we all
try to do is make logical code that is readable and maintainable. Try
looking at your code a year later and see if it makes any sense, and you
wrote it. Imagine what it looks like to us?

I'm not sure what you are doing but it looks like you are pulling 5
random entries from some file and sorting by date. A database is ideally
suited for this type of work and the select to do this is simple. This
has all the appearance of something you just kept fudging with until you
got what you thought you wanted.
