Re: Create array from directory

Greetings Mr. Wong, and thanks for your input. I have amended things as follows, and all is working to my satisfaction : -------------------------------------------------------- <?php $image_dir = '../graphics/'; $dir = opendir($image_dir); $gallery = array(); while ($file = readdir($dir)) { $filepath = ($image_dir . $file) ; if (is_file($filepath)) { $gallery[] = $filepath; } } closedir($dir); srand ((float)microtime()*1000000); shuffle ($gallery); //==================================================== for ($i = 0; $i < 4; $i++) { print '<td>'; print '<img src="' . ($gallery[$i]) . '" width="100" height="100"></img></td>' . "\n"; } ?> Thanks again for helping........
