What are some alternative methods for iterating through a directory in PHP besides using the readdir() function?

When iterating through a directory in PHP, an alternative method to using the readdir() function is to use the scandir() function. The scandir() function returns an array of all the files and directories in the specified directory. This can simplify the process of iterating through a directory as it eliminates the need for a while loop and individual calls to readdir(). 

$directory = '/path/to/directory';

$files = scandir($directory);

foreach ($files as $file) {
    echo $file . "\n";
}
