How can PHP's glob function be utilized in comparing files between directories?

To compare files between directories using PHP's glob function, you can first use glob to retrieve an array of file paths from each directory. Then, you can compare the arrays to find any differences in the files present in each directory. 

$directory1 = 'path/to/first/directory/';
$directory2 = 'path/to/second/directory/';

$files1 = glob($directory1 . '*');
$files2 = glob($directory2 . '*');

$diff1 = array_diff($files1, $files2);
$diff2 = array_diff($files2, $files1);

if(empty($diff1) && empty($diff2)) {
    echo "Directories have the same files.";
} else {
    echo "Directories have different files.";
}
