vars?

[The Red Guy]

Ok I might sound stupid or something, I just don't understand what's "vars" in something like $variable->vars['number']. Also, is the ' ' needed for arrays? Does this $variable->vars[number] do as well?

Well, if you wish to get something from an array in php you would do:



echo $arrayvar[user2];


So you could do something like



$arrayvar = array (
"user2" => "blogger"
);


Which could also be called as



echo $arrayvar[0];

In associative arrays, always use quotes around the index


$myarray['this']
$myarray[nothis]

Without the quotes will still work, but you just shouldnt do it.


PHP Manual: Arrays (http://ca2.php.net/manual/en/language.types.array.php)
This is wrong, but it works. Then, why is it wrong? The reason is that this code has an undefined constant (bar) rather than a string ('bar' - notice the quotes), and PHP may in future define constants which, unfortunately for your code, have the same name. It works, because the undefined constant gets converted to a string of the same name automatically for backward compatibility reasons.

Which means it applies to classes as well, but what's the difference between vars and var?

I'm not sure what you mean..?

vars has an 's' at the end? :confused:

Take this example from IPB functions.php:

/*-------------------------------------------------------------------------*/
//
// Load a template file from DB or from PHP file
//
/*-------------------------------------------------------------------------*/

function load_template( $name, $id='' )
{
global $ibforums, $DB, $root_path;

$tags = 1;

if ($ibforums->vars['safe_mode_skins'] == 0)
{
// Simply require and return

require $root_path."Skin/".$ibforums->skin_id."/$name.php";
return new $name();
}

Ah, because iPB is using classes, little Matt there has created a variable in a class called 'vars'. To access that variable, he had to make an instance of the object (class) which he named $ibforums. You access class vars by a pointer, and thus $ibforums->vars is there :)

Did that explain?

[The Red Guy]

Which means $vars is under $ibforums?

Yep
