Question

I want to know can I add a caption to this random script

<div style="background:transparent url(
 backgrounds/<?php echo 'image-'.rand(0,20).'.jpg'; ?>);"> 
 Welcome to my Site!
</div>

There’s another way it’s using an array for the caption:

$images = array(array("image 1" => "caption 1"),
                array("image 2" => "caption 2"),
                array("image 3" => "caption 3");

Can I add combine the two of them? Is it possible? If so, how do I do that?
If there’s no way. What else can I do? I appreciate any suggestion

Thanks

You could shuffle your $images array and grab the first index.

$images = array( array('file' => 'image1', 'caption' => 'Caption 1'),
                 array('file' => 'image2', 'caption' => 'Caption 2') );

shuffle($images);
$file = $images[0]['file'];
$caption = $images[0]['caption'];
