echo display_random_img($ads_array_1); // add or remove accordingly
?>

While searching on the internet for a viable PHP array randomizer function, this is what I ended up with. It works perfectly, there are url, alt, img_url.
I don’t know how to show text over/with the image?

Answer 1

Simple:

1) Add title to the array :

array(
    'url' => 'http://www.google.com/',
    'alt' => 'Google',
    'img_url' => 'images/1.png',
    'title' => 'Google Title'
),

2) Replace your function with

function display_random_img($array) {
    $key = rand(0 , count($array) -1);
    $link_url = $array[$key]['url'];
    $alt_tag = $array[$key]['alt'];
    $random_img_url = $array[$key]['img_url'];
    $title = $array[$key]['title'];
    list($img_width, $img_height) = getimagesize($random_img_url);
    return "<a href=\"$link_url\"><img src=\"$random_img_url\" width=\"$img_width\" height=\"$img_height\" alt=\"$alt_tag\" title=\"$title\" /></a>";
}

If You want Your title to be next to the image or whatever, just make the relevant corrections in html :

return "$title : <a href=\"$link_url\"><img src=\"$random_img_url\" width=\"$img_width\" height=\"$img_height\" alt=\"$alt_tag\" title=\"$title\" /></a>";
