How to make a console call in yii2?

Question

Yii

Gentlemen, please tell
me 1. installed on OpenServer YII2 basic, I see a test site ( mysite.local )
2. I open CMD, go to the URL of my site ( c:\My\OpenServer\OpenServer\domains\mysite.local>_ )
to see treasured inscription
3. I enter yii <hello> [-m=hello]
I get - Cannot find the specified file.
As usual, the problem of discovering something new. Tell me how to make a console call in yii2?
(Google brought the courts, there are no video lectures about this on YouTube)

Answer 1

what does php -v say in the console?
Why doesn't Openserver change PHP versions?

Answer 2

Good afternoon.
Enter in the console
and get a list of available commands

Answer 3

Parse error: syntax error, unexpected '[' in C:\My\OpenServer\OpenServer\domains\mysite.local\vendor\guzzlehttp\psr7\src\functions.php on line 78

I saw this. YII2 itself eats, but did not change anything, only a test run, for the first console call
(changed the php version, from 5.5 and higher - the same way)
