What are the advantages of using the glob() function in PHP to scan directories and create arrays?

When scanning directories in PHP, using the glob() function can be advantageous as it simplifies the process of retrieving files that match a specific pattern. It allows for easy filtering based on file extensions or names, and automatically creates an array of matching files, making it convenient to iterate over them for further processing. 

// Scan a directory for all .txt files and store them in an array
$files = glob('path/to/directory/*.txt');

// Iterate over the array of files
foreach($files as $file) {
    echo $file . "\n";
}
