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)

You also forgot the '> to end the src.

$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" />';

?>

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");

The image “http://xxx.com/box/” cannot be displayed, because it contains errors.

I get that when using your code (--ss--).

Put it right at the top before anything else ;).

you need to use php-gd commands to generate the image.

more simple to just leave it as you had originally.

I want to use it in my sig, so that's why I want to turn it into an image.

Nevermind, I figured it out.

Editing the other stuff out, you should get yourself an image rotation. :)

[Invent]

<?php

$images = array( "lol", "wut", "dongs" );

$random = rand( 0, ( sizeof( $images ) - 1 ) );
$file = $images[ $random ] . '.gif';

$size = filesize( $file );

header( "Content-Type: image/gif" );

$f = fopen( $file, "r" );

while( $buf = fread( $f, $size ) )
{

print $buf;

}

fclose( $f );

?>


You could use something like that if you don't want to waste server resources generating an image using php gd everytime someone loads the image.

(You could easily just use file_get_contents but there was a reason I used fopen, lol).
