return in PHP code

when we use return in PHP on global scope, after return, does execution just stop? or processing will go on?

<?php

if(defined("A")) return;
define("A", true);

echo "Hello";

if(defined("A")) return;
define("A", true);

echo "Hello";
?>

If you want to stop a script, you'd better use exit, because return should be only used in functions !

http://php.net/manual/en/function.return.php
http://php.net/manual/en/function.exit.php

In your case, the script will end as said by the documentation : return will also end the execution of an eval() statement or script file

Your script will be stopped after first return

As documenation says:

If return is called from within the main script file, then script execution ends
