[Resolved] how to list certain MIME types in a directory

[mband2000]

Hello,

I have a scripts that reads a directory full of images and then outputs the listing of .jpg images on the page.

My problem is that the script is listing those little log files that my server places in each folder.

How can I set my script up to only allow it to view the .jpg images.

Also can someone explain to me how to read the total size of a certain directory..

to display only files with the extension 'jpg' you would need to put an if statement in your code. without seeing what your code is, something like this should work.

  if (strtolower(substr(strrchr($file,"."),1)) == 'jpg') {
    echo $file;
  }

for your question of 'how to find a directory size?' i got this from the manual.

function dirsize($dirName = '.') {
  $dir  = dir($dirName);
  $size = 0;
  while($file = $dir->read()) {
      if ($file != '.' && $file != '..') {
          if (is_dir("$dirName$file")) {
              $size += dirsize($dirName . '/' . $file);
          } else {
              $size += filesize($dirName . '/' . $file);
          }
      }
  }
  $dir->close();
  return $size;
}

$path = '/path/to/dir/';
$size = 0;
$handle = opendir($path);
while (($filename = readdir($handle)) !== false)
{
	$pathinfo = pathinfo($filename);
	if (isset($pathinfo['extension']) && $pathinfo['extension'] == 'jpg')
	{
		$size += filesize($path . $filename);
		echo $filename . '<br>';
	}	
}

echo '<br>total size: ' . $size . ' bytes';
