Function/Constant autoloading

Hi,

thanks for your reply, but I'm not talking about class loading (because
thats already possible). I'm talking about autoloading of userspace
functions and constants

// /path/to/my/functions.php
namespace my\functions;

const THING = 'I am constant!';

function helloWorld () {
echo "hello World;
}

// /path/to/some/other/file.php
namespace foo;
use my\functions;

functions\helloWorld(); // fail!
echo functions\THING;

Hi:
maybe Yaf_Loader can be used for meet this requirement.

it's a internal autoload function:

Each namespace separator is converted to a `DIRECTORY_SEPARATOR` when

loading from the file system.

Each "_" character in the CLASS NAME is converted to a

DIRECTORY_SEPARATOR. The "_" character has no special meaning in the
namespace.

The fully-qualified namespace and class is suffixed with ".php" when
loading from the file system.

As examples:
  \Doctrine\Common\IsolatedClassLoader =>

/path/to/project/lib/vendor/Doctrine/Common/IsolatedClassLoader.php

 \namespace\package\Class_Name =>

/path/to/project/lib/vendor/namespace/package/Class/Name.php

 \namespace\package_name\Class_Name =>

/path/to/project/lib/vendor/namespace/package_name/Class/Name.php

thanks

Hi,

Maybe this topic occured already, then sorry when I'm wasting your time, but
I'm wondering, why there is no autoloading for functions and
(namespace)constants.

When a class is not found, then an userland function is called. Thus I don't
see a reason, why something like this doesn't exists for functions and
(namespace)constants too, because using them is quite uncomfortable right
now compared to classes and the decision how to load them would be on the
developers-side anyway.

Hi,

Thanks for your reply

There is lazy loading for functions via apc.lazy_functions (although I've
not properly tested this yet). That doesn't require any userspace code
changes.

As far as I can see this is for built-in functions only. The problem I
see is, that APC cannot know, where my functions are located and
therefore cannot load it without userspace help.

For define() I'm not aware of anything allowing for lazy loading constants
(define() is just a function call).

However there are a few approaches for avoiding define(), you could look at
apc_define_constants(), http://pecl.php.net/package/hidef and
http://pecl.php.net/package/chdb, you could also switch to class constants
and lazy load your classes.

Maybe my description were a little bit misleading: I was talking about
especially namespace constant like

namespace my\ns;
const FOO = 'BAR';

I know I can use class constants instead (as well as I can use static
methods instead of functions), but that makes me feel, that functions
and namespace constants are more or less useless now.

I haven't
