How can the use of glob() instead of scandir() improve efficiency when reading files from a directory in PHP?

Using glob() instead of scandir() can improve efficiency when reading files from a directory in PHP because glob() returns an array of file paths that match a specified pattern, while scandir() returns an array of all files and directories in the specified directory. By using glob() with a specific pattern, we can filter out unwanted files and directories, resulting in faster processing. 

// Using glob() instead of scandir() to improve efficiency
$files = glob('/path/to/directory/*.txt');
foreach ($files as $file) {
    echo $file . "\n";
}
