Well, first off you've broken the golden rule, which is: Don't mix the :-type syntax
with the {}-type or completely bare syntaxes.
In more detail: on reaching the "else", PHP matches it with the nearest preceding if;
this is the "If (1) echo ..." line, which isn't using :-type syntax, so it expects the
else also not to use :-type syntax -- so the : is a parse error.
Using :-type syntax, you *must* write this as:
if (1):
if (1):
echo "hello";
endif;
else:
endif;
> this works fine (no parse error):
> <?
> if (1):

> if (1) echo "hello";
> endif;

This is because the "else" now matches the first "if (1):", which uses :-type syntax,
so the "else" is expected to have a ":" after it, which it does -- so no parse error.
Cheers!
