function micro_time() {
$temp = explode(" ", microtime());
return bcadd($temp[0], $temp[1], 6);
}
$time_start = micro_time();
$now = time();
$min_timeout = time() - (60 * 15);
$images = array('image1.jpg', 'image2.jpg', 'image3.jpg', 'image4.jpg');
$temp_file = "C:\logo_time";
$file_time = @fileatime($temp_file);
$image_loc = @file($temp_file);
if (!file_exists($temp_file) || !isset($file_time))
{
$f = fopen($temp_file, "w+");
fwrite($f, (isset($image_loc[0]) ? $image_loc[0] : $images[0]));
fclose($f);
touch($temp_file);
}
elseif (($file_time >= $min_timeout) && isset($file_time))
{
$image_set = $images[0];
$count_images = count($images)-1;
$i=0;
foreach ($images as $image)
{
if ($image == $image_loc[0] && ($i < $count_images))
{
$image_set = $images[$i+1];
break;
}
$i++;
}
unset($images, $count_images);
