3 rare things that I don't know the reason

Hi devs,

1) Im trying to create a yml doc with some array, the doc get created but inside the doc there is --- at the begin of the file, what is this?

$acceptance = [
    'class_name' => 'AcceptanceTester',
];

string(...) "--- <------- WHAT IS THIS?
class_name: AcceptanceTester
"

2) I would like to create something like this:

class_name: AcceptanceTester
modules:
    enabled:
        - PhpBrowser
        - WebHelper

This is my code:

$enabled = "- PhpBrowser \n- WebHelper";
$acceptance = [
    'class_name' => 'AcceptanceTester',
    'modules' => [
        'enabled' => $enabled,
    ]
];

But instead I get:

---
class_name: AcceptanceTester
modules:
    enabled: | <------------ WHY IS THIS HERE?
        - PhpBrowser 
        - WebHelper

With a pipe( | ) and the previous --- that I previously explained

3) Im trying to create a field with this format:

 url: 'http://someurl.com'

This is the code:

$module = [
    'modules' => [
        'config' => [
            'PhpBrowser' => [
                'url1' => $domain,
                'url2' => "'$domain'",
                'url3' => "$domain",
                'url4' => '\'$domain\''
            ]
        ]
    ]
];

And I get:

modules:
    config:
        PhpBrowser:
            url1: http://someurl.com
            url2: "'http://someurl.com'"
            url3: http://someurl.com
            url4: "'$domain'"

Any solution, Thank you very much in advance!

1. is correct, that's how YAML indicates the beginning of a document.

2. is also correct, the | indicates that the following is a string. It should probably look like this:

$acceptance = [
    'class_name' => 'AcceptanceTester',
    'modules' => [
        'enabled' => array(
            'PhpBrowser',
            'WebHelper'
        ),
    ]
];

(I think, I haven't tested it.)

3. Either of these should work (again, haven't tested)

$module = [
    'modules' => [
        'config' => [
            'PhpBrowser' => [
                'url1' => "'" . $domain . "'",
                'url2' => "'{$domain}'",
            ]
        ]
    ]
];
