Are there any specific considerations to keep in mind when counting files in a folder with PHP?

When counting files in a folder with PHP, it is important to consider that the folder may contain subdirectories. To accurately count all files, you will need to recursively search through all subdirectories as well. One way to achieve this is by using a recursive function that counts files in the current directory and then calls itself for each subdirectory found.

function countFilesInFolder($folder) {
    $count = 0;
    $files = scandir($folder);

    foreach ($files as $file) {
        if ($file != '.' && $file != '..') {
            if (is_dir($folder . '/' . $file)) {
                $count += countFilesInFolder($folder . '/' . $file);
            } else {
                $count++;
            }
        }
    }

    return $count;
}

$folder = 'path/to/folder';
$fileCount = countFilesInFolder($folder);
echo "Total files in folder: " . $fileCount;
