How can the glob function be utilized to efficiently check the existence of multiple files in PHP?

To efficiently check the existence of multiple files in PHP, the glob function can be utilized. This function allows for pattern matching to find files that match a specified pattern. By using glob with a wildcard pattern, we can easily check if multiple files exist in a directory without having to iterate through each file individually. 

$files = glob('path/to/directory/*.txt');

if ($files) {
    echo "Files exist: " . implode(', ', $files);
} else {
    echo "No files found.";
}
