PHP not working in MAMP PRO. How to setup?

Question

PHP

Updated to version 6.3.1 from 5.7. In the previous one, everything worked ok on all versions of php, but after the update, projects start only on 5.6, nothing further.
Decided to check something. I created a test host and added an entry to index.php there. I get an empty page in the layout of which . But if you write then everything works, but as you understand, this is not a solution to the problem. Tell me where to dig?
<?echo phpinfo();?>
<!--?echo phpinfo();?-->

<?php echo phpinfo();?>

Answer 1

In the php settings of the selected version, enable the short_open_tag option
