[SOLVED] Autoloads for classes?

[LemonInflux]

Hello. I've been slowly migrating to PHP5, and I've been looking at the __autoload() function. I've been wondering about this, done a little searching, and have yet to find a definite solution.

 

My question is, can you redefine __autoload()?

 

Say I have a class called core. In core, I want this:

 

function __autoload($class) {
include_once dirname(__FILE__) ."/$class.class.php";
}

 

Now, in another class, called view, I want this:

 

function __autoload($class) {
include_once dirname(__FILE__) ."/views/$class.class.php";
}

 

Is this possible? Before you ask, no I can't check it, because I have no way of testing it today

 

Thanks in advance

While I'm not sure about the exact answer to your question I have implemented something similar in the past...

 

I used naming conventions to define where to autoload from, for example NewsController would be loaded from the controller directory and NewsModel would be autoloaded from the model directory. Of course you need to be careful about security with an implementation like this, and it's definitely not what I use to load my controllers and models, it's just an example.

 

Something to consider perhaps?

Thanks, but it's not really what I'm looking for. I don't want to have to use a function, and the autoload() allows naming conventions. I just want to try, if possible, to use autoload().

Just checked, no you can't redefine __autoload()

 

Better answer?

[LemonInflux]

Ugh, even if it's in different classes?

Unfortunately autoload() is a procedural function... you would probably need namespaces for that. Namespaces are in php6 though last time I checked.

Namespaces..?

I'm not sure how php6 will implement their namespaces though so holding off might not be the best bet.

 

Another alternative to a naming convention is that you could have an ini file or a php config file with the locations of the "special case" classes that the autoload consults before loading the class.

Aah, I see. Thanks then, topic closed.
