Good day,

While I've been using php for more than a little while now, I've never
understood why the use of the "<?= ...?>" short tag is noted "to be
avoided".

Or rather, I understand that there's an option to disable it, and that's
why it's noted in this way, but I don't understand why it's disabled?
What's gained by writing <?php echo some_function(); ?> over <?=
some_function(); ?>

Thanks in advance.

Cheers,
Mike
