Questions about the API

Hello all. I am new here.
My first question is: how can I access a public function defined in one of the <Namehere>API.php files from a plugin.
For instance, how would I access the harm function defined in the entilietyAPI.php file from a plugin.

My second question is what is the order of inheritance in the api.
This may answer the first question.
(More questions to come...)

Not the exact answer. The name of the api is defined at lines 199-207 at ServerAPI.php
If you make a plugin's api like economys, you can also define ir like this.

And @Falk, there is no any rules on the plugin development that you must have a field called api in a plugin. For instance, I like to use, like in function init(), I like to write:

PHP:

$s=ServerAPI:: request ();
$c=$s->api->console;
$s->schedule...
$s->addHandler...
$c->register...

I am pointing this out just to remind people not to use $this->api when they are working with multiple classes.

What? There are no any relationship between APIs, except that Server API contains fields of other APIs.

Anyway whatever u mean, there is no API extending another.

Another question

why does

PHP:

        $po[] = $this->api->player->online();
        echo $po[0];


Return:
Arrary

Now with this:

PHP:

        $po[] = $this->api->player->online();
        echo $po[0];
        foreach($po as $key => &$pyr){
            echo $pyr;
            }
        unset($pyr);
        echo "\n";

I get ArrayArray.
What am I doing wrong?
I don't use php often.

Use implode()

now with

Code:

                $po[] = $this->api->player->online();
        echo "".implode($po, "',");
        echo "\n";

returns
Array

Yup!

Why don't you use $this->api->player->getAll()? This will return an array of online Player objects.

So
$po[] = $this->api->player->getAll();
echo $po[0];
echo "\n";
returns
Array
