Are there any best practices to follow when reading directories and creating arrays of file names in PHP?

When reading directories and creating arrays of file names in PHP, it is recommended to use the `scandir()` function to retrieve a list of files in a directory. This function returns an array of files and directories in the specified directory. Additionally, you can filter out any unwanted files by using functions like `array_filter()` or `preg_grep()`. 

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

// Get an array of files in the directory
$files = scandir($dir);

// Filter out unwanted files (for example, remove '.' and '..')
$files = array_filter($files, function($file) {
    return !in_array($file, ['.', '..']);
});

// Print the array of file names
print_r($files);
