php随机生成字符串可以自己定义自己所需要的长度,在实际应用开发中,经常遇到。
复制代码 代码如下:
//随机生成字符串
function random($length) {
     srand(date("s"));
     $possible_charactors = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ";
     $string = "";
     while(strlen($string)          $string .= substr($possible_charactors,(rand()%(strlen($possible_charactors))),1);
     }
     return($string);
}
