Use a for loop to set all values of the N * N two-dimensional array to 1.

Use a for loop to set all values of the N * N two-dimensional array to 1.

Let's just talk about the code.

<? Php // use a for loop to set all values of the N * N two-dimensional array to 1 $ n = 3; $ a = []; for ($ I = 0; $ I <$ n * $ n; $ I ++) {$ a [$ I/$ n] [$ I % $ n] = 1 ;} print_r ($ );

In the preceding example, we use a for loop to set all values of the N * N two-dimensional array to 1. This is all the content that I want to share with you, we also hope that you can support the customer's home.
