[SOLVED] exclude numbers from rand() ?

[aebstract]

Not sure exactly how to approach what I am needing to do. I'm sure there are many different ways and I have a few ideas but nothing too solid, so.. Basically, Let's say I have 5 images. I want to display them in a random order. What I was going to do was assign a number to each one and grab a random number, and just take that number that was taken out of the random function and keep going until all the images are posted. Though, I bet there is an easier way to do this. Possibly somehow put all the images in an array and display the array in a random order? Any help as to what I can do and some guidance in the right direction would be awesome!

somthing like this?

 

<?php

$myarray = array();

for($i=0;$i<=5;$i++)
{
$myarray[] = 'filename'.$i.'.jpg';
}

shuffle($myarray);

foreach($myarray as $a)
{
echo $a.'<br />';
}

?>

Same concept, fewer loops

 

<?php

$max = 5;

$range = range(1,$max);
shuffle( $range );

foreach ( $range as $id )
echo "picture$id.jpeg <br />";

?>

$max = 3;

$range = range(1,$max);
shuffle( $range );

foreach ( $range as $id ) {
$displaybanner .= "$banner$id";
}

This is doing exactly what I need it to do, except I'm having trouble getting my display to work right. Do you know how to add the word banner in front of the $id number and turn the whole thing in to a variable $banner# ?

Thanks!

Can you give an example of an image name?

 

It could be either

${'banner' . $id}

 

or

 

${$banner . $i}

First one worked perfect, file name isn't important for that

Thanks everyone
