DZone Snippets: glob code

Image aggregator

Minimiscience (Guildorn Tanaleth) — Thu, 05 Jul 2007 04:08:17 GMT

This PHP snippet outputs the contents of a table (beginning & ending tags not included) containing all the images from the current directory.

 $columns = 3;

 $im = glob("*.{gif,jpg,png}", GLOB_BRACE);

 $rows = ceil(count($im) / $columns);

 for ($i = 0; $i < $rows; $i++) {

  echo "\n";

  for ($j = $columns*$i; isset($im[$j]) && $j - $columns*$i < $columns; $j++) {

   echo "$im[$j]
";

  }

  echo "";

 }
