PHP Bug Type: Reproducible crash
Bug description: defined() doesn't work properly.
Description:
------------
People use defined() to check if a constant is defined so they can later
use constant() without any warning or error.
I found these bugs:
1. defined() doesn't forward exceptions
2. defined() try to load class from an invalid constant name (false:::::)
3. produce invalid error line white raising an error if autoloader thrown
an exception.
There should be a $autoload param like in class_exists() and
interface_exists().
Reproduce code:
---------------
<?
function autoloader($class) {
throw new Exception(); // line 3
}
spl_autoload_register('autoloader');
function foo() {
defined('false:::::::'); // line 9
$a = 10;
$b = 11;
} // line 12
foo(); // line 14
?>
Expected result:
----------------
>From PHP 5.1.2:
Fatal error: Uncaught exception 'Exception' in /root/x.php:3
Stack trace:
#0 [internal function]: autoloader('false')
#1 [internal function]: spl_autoload_call('false')
#2 /root/x.php(9): defined('false:::::::')
#3 /root/x.php(14): foo()
#4 {main}
thrown in /root/x.php on line 3
Actual result:
--------------
