[PHP-BUG] Bug #73608 [NEW]: inconstistent const behavior

From:             spam2 at rhsoft dot net
Operating system: 
PHP version:      7.0.13
Package:          PHP Language Specification
Bug Type:         Bug
Bug description:inconstistent const behavior

Description:
------------
why can't you still not use 'const' inside a if-statement?

"because it's compile time" is a lie which is easily to realize because
otherwise CONST_B could never contain the value of CONST_A which was
defined in the if-statement before

[harry@srv-rhsoft:/downloads]$ cat test.php
<?php
 $x = 1;
 if($x == 1)
 {
  define('CONST_A', 'A');
 }
 const CONST_B = 'TEST ' . CONST_A;
 echo CONST_B . "\n";
?>

[harry@srv-rhsoft:/downloads]$ php test.php
TEST A
