How can the glob() function be used to efficiently retrieve and filter files in PHP?

The glob() function in PHP can be used to efficiently retrieve and filter files based on a specific pattern. By providing a pattern as an argument to glob(), you can retrieve a list of files that match that pattern in a directory. This can be useful for tasks such as listing all files with a specific extension or files that start with a certain prefix. 

// Retrieve all PHP files in a directory
$files = glob('/path/to/directory/*.php');

// Iterate over the files and do something with them
foreach ($files as $file) {
    echo $file . "\n";
}
