Bug description:Function declarations inside if/else statements don't work correctly

Description:
------------
When declaring a function inside an if/else statement, the latter
declaration is 
honoured regardless of which branch the if/else statement took.

Test script:
---------------
<?php

if(true)
{
    function foo()
    {
        echo "first foo.";
    }
}
else
{
    function foo()
    {
        echo "second foo.";
    }
}

foo();

Expected result:
----------------
first foo.

OR:

Syntax Error: Cannot declare function inside conditional statement

Actual result:
--------------
second foo.
