Codesnippets in arrays

flyhigh

I'm building a menusystem where several restrictions is part of the array read from file.

Say I got an array $restricts which contains different constrictions like this:

$restrict[0][0]=is_loggedin()==1
$restrict[0][1]=is_locked()==0
$restrict[1][0]=is_loggedin()==0

What I want do do is simply this:

if ($restrict[0][0] && $restrict[0][1]) return true;

Now this doesn't work, and I can't figure out why. I tried using the eval() function, but I always get parse_errors on them.

Anyone able to help me out?

Wops, constrict = restrict.. 😉

Not clear from your writing, but do I take it that

$restrict[0][0]=is_loggedin()==1
$restrict[0][1]=is_locked()==0
$restrict[1][0]=is_loggedin()==0

is part of a text file? And that you tried eval() on each line to evaluate it? If so, then they're missing semicolons on the end, like other PHP statements.

If all of your file looks like this, and you're reading all of it, you could just include() it.

Here is a piece of the textfile:

It is being read from the file, and I manipulate the arrays so I get one fat array out of all of it. It includes the name of the link, the text of it, and the id of it.

All restrictions to each item on the menu is like this: $menues[tm][$id][$name][RESTRICT][$i]

Now doing:
if ($menues[tm][$id][$name][RESTRICT][0]) won't work for those items that has one restriction. Using eval on this:
if (eval($menues[tm][$id][$name][RESTRICT][0])) just gives me parse errors..

Got any other ideas?

It looks awfully baroque, but then I'd use a database.

I notice from the documentation (www.php.net/eval) that "...the string passed must be valid PHP code, including things like terminating statements with a semicolon so the parser doesn't die on the line after the eval(), and properly escaping things in code_str."

so I'd try

if (eval("return $menues[tm][$id][$name][RESTRICT][0];")) to make sure that the thing being eval()ed is a genuine PHP statement.

Yeah, I know its baroque, but I read the file only once though, so it is slightly faster than reading it from the database, which is kinda busy all the time. =)

Sadly the eval thing didn't work.. Oh well, will try do it another way.

Thanks for your help though.
