Re: [PHP] nested if parse error
could somebody explain me please what is wrong with this
piece of code?
?
if (1):
if (1) echo hello;
else:
endif;
?
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.
now it's clear to me
anyway it's funny that this works fine :-)
?
if (1):
if (1) echo hello;
$a = 1;// here can be anything else
else:
endif;
?

Nope, that makes perfect sense too. Think about where your second if(1) terminates -- is it still open when the parser reaches the else:? As I said before, it just gets way too confusing if you try to mix the :-type syntax with anything else: if you use it at all, use it for *everything*. Cheers!

RE: [PHP] nested if parse error
I think coding without the use of brackets and line seperation will drive
you mad!
A working copy of your code:
?
if (1):
if (1): echo hello;
else:
endif;
endif;
?
This in my humble op is so much neater and you can debug this in a second.
if (1){
if (1) {
echo Hello;
}
} else {
}

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):
else:
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!
