Are there any best practices for filtering out specific file types when using PHP to scan directories?

When scanning directories using PHP, it may be necessary to filter out specific file types to only process certain files. One way to achieve this is by using the `glob` function along with a file extension filter. This can be done by specifying the file extension to include or exclude in the glob pattern. 

// Specify the directory to scan
$directory = '/path/to/directory/';

// Specify the file extension to filter out
$fileExtension = 'txt';

// Scan the directory and filter out specific file types
$files = glob($directory . '*.' . $fileExtension);

// Loop through the filtered files
foreach ($files as $file) {
    echo $file . "\n";
}
