Image rotator [PHP]

[wsg14]

<?php

$img[0] = "images/box_red.png";
$img[1] = "images/box_blue.png";
$img[2] = "images/box_purple.png";
$img[3] = "images/box_green.png";

$total = count($img) - 1;
$rand = rand(0,$total);

echo '<img src="$img[ $rand ]" border="0"';

?>

That doesn't display what I want it to (images/box_xxxx.png). It displays the actual variable ($img[ $rand ]). +rep

(using an edited version L?KE's code)

Oops, mod delete.

You also forgot the '> to end the src.

$img[1] = "images/box_blue.png";
$img[2] = "images/box_purple.png";
$img[3] = "images/box_green.png";

$total = count($img) - 1;
$rand = rand(0,$total);

echo '<img src="'.$img[ $rand ].'" border="0" />';

?>

Thanks Craig and Excellent.

if you want the .php file to be detected as an actual image so your can include it via <img src="..... just set the file as header("location:image.jpg");

No.. that would redirect the url to "image.jpg"

I was just going to ask that, how would I do that?

I believe it's

header("Content-type: image/png");
