What are the potential pitfalls of using opendir() and readdir() functions in PHP?

One potential pitfall of using opendir() and readdir() functions in PHP is that they require manual handling of the directory iteration process, which can lead to errors if not done correctly. To avoid this, you can use the glob() function, which simplifies directory iteration and file matching in a more concise and efficient way. 

// Using glob() function to iterate through files in a directory
$files = glob('/path/to/directory/*');
foreach ($files as $file) {
    echo $file . "\n";
}
