Solved Array reading

Hey, i want to know how to read an array
Example:
I have this on my config.yml file:

Code:

person1: [10, 15, 13]

Question:
1. I want to get that on my Main.php as array idk how to do it
2. Can i detect 10 is available or no on Main.php (detecting on array)
3. How to make array separate one another
Thats it!

 

I am not sure about my code....

1.

PHP:

$this->cfg = $this->getConfig()->getAll();

2.

PHP:

$get10 = $this->cfg["person1"][10];

3.

PHP:

$setcfg = this->cfg->set(["hi"]["first"], 1);

 

Not, this

PHP:

$get10 = $this->cfg["person1"][0];

 

Like this maybe? ;

PHP:

$person = $this->cfg->get("person1");

if(in_array(10, $person)){
#do stuff
}

 

he said "(detecting on array)"

 

Yep, its will works

 

Oh, sorry. I didn't see

 

You can use array_slice()
