A:
It's part of the short_open_tag. Basically <?=$foo?> is equivalent to <?php echo $foo; ?>

Short_open_tag is primary <? ?>. "Short_open_tag also affects the shorthand <?=, which is identical to <? echo. Use of this shortcut requires short_open_tag to be on" - citation from php.net. So it is not basically short_open_tag.

A:
<?= $foobar ?> is a shortcut for <?php echo $foobar; ?>.
I wouldn't recommend using these short tags because in some webserver environments they are disabled via PHPs configuration.

Any decent PHP application requires a lot of configuration options, from mod_rewrite to memory_limit and post_max_size. Go tell everyone these are not recommended for use

A:
See the short_open_tags setting.
<?= is identical to <? echo and use of it requires short_open_tag to be on. A term to search for would be "short tags".
As an example: <?='hello'?> is identical to <? echo 'hello' ?> which is a short form of <?php echo 'hello' ?>.
