Regular expression for Yii2 password?

Question

Regular Expressions

Good afternoon! I just started working on Yii2, and more specifically, I'm learning.
There is a question: how to set 'match pattern' for the password, using the condition from the picture?

Very urgent! Thank you!

Answer 1

The presence of at least two digits, two letters and two special characters is checked.
Length is at least 6 characters.

'pattern' => '(^(?xi)
                (?=(?:.*[0-9]){2})
                (?=(?:.*[a-z]){2})
                (?=(?:.*[!"#$%&\'()*+,./:;<=>[email protected]\[\]^_`{|}~-]){2})
                .{6,}$
              )'
