PHP print ring digital circles _ PHP Tutorial

PHP prints a ring number circle. Example: $ I [number]; print the following figure: 12341213145111615610987 *** two-dimensional array sorting * @ paramarray $ array * functionsort_recursive ($ array) {foreach ($ array as the title:
$ I = [number];
Print the following figure:

1 2 3 4
12 13 14 5
11 16 15 6
10 9 8 7
