可以获得由字符串标签定义的随机数？ 喜欢{1-100}

Question

I would like to get a random value between two numbers in a string. For example, a string {1-100} returning something like rand (1,100). It's possible?

Answer 1

 <?php
       $string = "{1-100}";
       $split = split("-",$string);
       if (count($split)==2){
           $lower = intval(preg_replace('/\D/', '', $split[0]));
           $upper = intval(preg_replace('/\D/', '', $split[1]));
           $random = rand($lower, $upper);
       }
