What are the best practices for iterating through files in a directory in PHP, and how can the glob() function simplify this process compared to using readdir()?

When iterating through files in a directory in PHP, using the glob() function is a more efficient and concise way compared to using readdir(). Glob() allows you to easily retrieve an array of file paths that match a specified pattern, eliminating the need for manual iteration and filtering. This simplifies the process and makes the code cleaner and more readable. 

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