Image Rotator Script
Wed, 11 January, 2006 – 1:09 am
I've finally gotten around to adding an image rotator script for the top header of this blog to rotate through a few different images. I'll be adding more once I've downloaded them off my mobile phone. For anyone who's interested in the PHP code:
$images = array(
'paris-subway.jpg' => 'The Metro : Paris',
'cube-houses.jpg' => 'Cube Houses : Rotterdam',
'snow-trees.jpg' => 'Snow covered trees : Austria',
'mountain-sunset.jpg' => 'Sunset over the mountains : Austria',
'paris-sunset.jpg' => 'Sunset on the River : Paris',
'wales-sunset.jpg' => 'Welsh Sunset'
);
// now shuffle the array items randomly
$filenames = array_keys($images);
shuffle($filenames);
// and pull out 3 images stored in the variables $image0, $image1 and $image2
for ($i = 0; $i < 3; $i++) {
$thumb = "thumb".$i;
$altxt = "altxt".$i;
$$thumb = $filenames[$i];
$$altxt = $images[$filenames[$i]];
}
Then all you need to do is reference these image variables whereever you want them i.e.
<img src="pics/<?php print $image0; ?>" alt="<?php print $altxt0; ?>" />
Thanks to JasonD on DDN for reminding me about the shuffle() function!
