@NogDogAug 03.2011 — #Well, you could always use the $GLOBALS array, I suppose. However, any such use of global variables is counter to the spirit and intent of OOP, and I'd rather see you passing the object as a parameter to the functions that need to use it, or as a compromise creating a singleton Registry object that could contain the object in question and then be accessed as/when needed.@NogDogAug 03.2011 — #It's not really clear to me what you want to do, but maybe you can do:

If you are dead set on using a PHP anonymous function in that situation, then using the use() functionality that is part of anonymous functions seems like a logical solution.* It would also allow you to use type-hinting in the function parameter list (instead of that moderately complex if clause I used earlier). If your goal is simply to imitate JavaScript and save yourself a tiny bit of typing, well, that's probably not a real good reason for application design in PHP or any other language. ?

Custom Superglobal
I have an instance of a class, how can I make that global without having to define it in all my functions?
Here is an example I have been trying to get to work:
My Class file:
[code=php]<?php
class phpLive{
// Some methods and properties here
}
$phplive = $_live = $live = $_ = new phpLive();
global $live;
?>
The Page:
[code=php]<?php
require_once ‘phpLive.php’;
$live->get_http(“http://google.com”)->callback(function(){
echo $live->title;
});
?>
But the above code gives me this error:
[QUOTE]
Notice: Undefined variable: live in C:wampwwwphpLiveindex.php on line 13
Notice: Trying to get property of non-object in C:wampwwwphpLiveindex.php on line 13
I don’t want to have to place “global $live” inside each function, so is there a way for me to access it?
BTW I have tried these as well without success:
[code=php]echo $this->title;
echo self::title;
