It's functionally the same as <?php echo $myACL->getRoleNameFromID($_GET['roleID']); ?>

To add to Mark's answer: The short_tags option must be enabled for the <?= syntax to be valid. This presents a major portability problem when moving to a server that has this option disabled.

See the PHP Manual for more info on short tags

It's the PHP Short Tag equivalent of printing.

From the PHP INI:

Using short tags is discouraged when developing code meant for redistribution ; since short tags may not be supported on the target server.

See "Are PHP Short Tags Acceptable to Use?" on StackOverflow.

The <?= ... > tag says to execute whatever is in ... and output the results.
