Hi,

I need help with writing a piece of code that counts all the folders in a specific directory and prints the number, then counts image files in the same directory but located in all the fullsize sub folder of each gallery.

Example:

-images
-galleries
-gallery1
- fullsize
-thumbs
-gallery2
- fullsize
-thumbs
-gallery3
- fullsize
-thumbs

and so forth.

So far I have this much of the code:

<?php


$directory='images/galleries';


$count=0;


if ($handle = opendir($directory)) {
    ;

    
    while (false !== ($file = readdir($handle))) {
        ;

        
        $file_parts=explode('.',$file);
        $file_parts_counts=count($file_parts);
        $file_type_location=$file_parts_counts-1;
        $file_type=$file_parts[$file_type_location];
        
        
        $count=$count+1;

    }

    closedir($handle);
}
echo "Galleries: <b>$count</b>";
?>

There are 31 folders in the gallery folder and count returns 39.

Can someone please shed some light here.

Thank you very much.

For : the root cause is that your loop is counting every entry returned by the directory read, not just actual gallery folders. was on the right track — a more robust approach is to explicitly enumerate directories and then, for each gallery, only inspect its fullsize subfolder.

A compact, reliable way to count galleries is to use glob() with GLOB_ONLYDIR and count():

$dirs = glob('images/galleries/*', GLOB_ONLYDIR);
$galleryCount = count($dirs);

See the glob() docs for details: glob() manual.

To count images only inside each gallery's fullsize folder you can also use glob() with an extension list, or fall back to SPL iterators for case-insensitive or more complex rules:

$total = 0;
foreach ($dirs as $g) {
    $fs = $g . '/fullsize';
    if (!is_dir($fs)) continue;
    $imgs = glob($fs . '/*.{jpg,jpeg,png,gif}', GLOB_BRACE | GLOB_NOSORT);
    $total += count($imgs);
}

If GLOB_BRACE isn't available on your system or you need case-insensitive matching, use FilesystemIterator + RegexIterator and iterator_count() instead. See the SPL docs: FilesystemIterator and RegexIterator.

Extra tips: ignore OS artifacts like .DS_Store or thumbs.db, verify files with exif_imagetype() or finfo_file() if extensions are unreliable (exif_imagetype), and consider caching results if you have many galleries to avoid repeated filesystem scans.

Thank you very much.

You're counting the "images" folder as well. Each directory will have a . directory in it that points to the parent directory.

So you're counting the parent directory when you count the ".".

You probably want.

while (false !== ($file = readdir($handle))) {
        ;

        if ($file == '.' || $file == '..') {
          continue; // skip this file
        }
        
        $file_parts=explode('.',$file);
        $file_parts_counts=count($file_parts);
        $file_type_location=$file_parts_counts-1;
        $file_type=$file_parts[$file_type_location];
        
        
        $count=$count+1;

    }

Also to get the file extension on one line:

$file_type = substr($file, strrpos($file, '.')+1);

You can also abbreviate:

$count=$count+1;

to:

$count++;
