How can the code snippet be improved by using glob() function in PHP?

The issue with the current code snippet is that it manually loops through all files in a directory to find files with a specific extension. This can be inefficient and error-prone. Using the glob() function in PHP simplifies this process by returning an array of files that match a specified pattern, such as all files with a specific extension. 

// Improved code snippet using glob() function
$files = glob('/path/to/directory/*.txt');

foreach($files as $file) {
    echo $file . "<br>";
}
