Are PHP short tags acceptable to use?
I have a question using
<?=$info ?> rather than <?php echo $info ?> when is <?= appropriate to use or has it be deprecated with 5.0
<?= must be marked as enabled in the config file, it's optional syntax I think...
Just be aware that if you move your code to another server where short tags are disabled, you may have a lot of work on your hands.
If you have the short_open_tag configuration setting enabled, you can use this. Generally, short tags are looked down upon, for readability and compatability's sake (if this is disabled by default in a later version, if you have to move your website to another server where this option is disabled, etc.)
However, if you can use it, it's not bad to use at all. If all you need to do is echo something, then use it if you wish.
