简单的PHP广告横幅/图像旋转器

Posted 2021-02-25

Pull banner ad or image code from a given text file into an array and randomize the order. Banner/image codes in the file should be separated by tildes (~).

function initializeAds($file) {
  $fcontents = file_get_contents($file);
  $ad_array = explode("~",$fcontents);
  shuffle($ad_array);
 
  return $ad_array;
}
 
$ad_banners = initializeAds('ad_banners.txt');
 
echo $ad_banners[0]; // first randomly ordered banner
echo $ad_banners[1]; // second randomly ordered banner, etc.
