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' ?>.

See also Are PHP short tags acceptable to use? here on SO.

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

They output what's inside them directly.

<?= "something" ?>

is a shortcut for:

<?php echo "something"; ?>

These (together with <? ?>) are called short tags. See here (short_open_tag)

<?= $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.

php

yes you can done it using .htaccess. In your .htaccess file, add this

php_value short_open_tag 1

Now you can check files with <?='hi';?> instead of <?php ?>
