php生成一个随机的密码,方便快捷,可以随机生成安全可靠的密码。

分享代码如下

<&#63;php

header("Content-type:text/html;charset=utf-8");

function getRandPass($length = 6){
 $password = '';
 //将你想要的字符添加到下面字符串中,默认是数字0-9和26个英文字母
 $chars = "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"; 
 $char_len = strlen($chars); 
 for($i=0;$i<$length;$i++){
 $loop = mt_rand(0, ($char_len-1));
 //将这个字符串当作一个数组,随机取出一个字符,并循环拼接成你需要的位数
 $password .= $chars[$loop];
 }
 return $password;
}
echo getRandPass(12); //随机生成一个12位数的密码

&#63;>
 

 希望本文对大家学习php程序设计有所帮助,大家可以试着更改生成密码位数,希望大家喜欢。
