If I have this array: $array = ['1', '2', '3'];
如果我有这个数组：$ array = ['1'，'2'，'3'];
I would like to replace all values in that array with asterisk sign *. Essentially, I want to get array like this: $new = ['*', '*', '*'];.
我想用星号*替换该数组中的所有值。基本上，我想得到这样的数组：$ new = ['*'，'*'，'*'] ;.
What is the best way to do this ? I am hoping that there is some short simple solution for this.
做这个的最好方式是什么 ？我希望有一些简单的简单解决方案。
Thanks in advance.
