Clearing things up

I took a couse by sololearn(ios app) on PHP now ive done a little studying and i feel like i have this right but i wanna make sure

this is how u create a config

PHP:

$config = $this->config = new config("config.yml");


And to get a config

PHP:

$this->config->getConfig("config.yml");


Please correct me if im wrong

Incorrect. Please refer to JoinCommands and look at the code, I think it'd be simple enough for a beginner to understand. It should be $config = $this->getConfig(), not $config = $this->config = $this->getConfig(). For the second one, it should just be $this->getConfig() and not $this->config->getConfig("config.yml").

Okay So to create a config named config.yml all i have to do is

PHP:

$this->saveDefaultConfig();


And to get data from the config U just do

PHP:

$this->getConfig->get("key") === value;


Also is it neccesary to user

PHP:

 ===

? Can u just use

PHP:

 ==

just curious because using 3 feels like an extremity to me i just prefer to say equal to not identical to

Yes, yes(depending on circumstances), no, and sure, why not. Just look here: http://php.net/manual/en/language.operators.comparison.php

I get how === and == work but i dont get what the difference is like where would i need one instead of the other?

Just look at the link I gave you it gives detailed descriptions for everything.

It is very different. If you have 2 strings (Ex: "#Roasted" and "#Roasted") using either is ok.

PHP:

if("#Roasted" ==  "#Roasted")

if("#Roasted" ===  "#Roasted")

But if you compare an integer and a string (Ex: 1 and "1") == would return true but === would return false.
Why? == means Equal and === means Identical.
When you use equal, maybe they are different types but PHP would do something called Type Juggling.
Identical: DID YOU PASS 2nd GRADE MATH???
