这篇文章主要介绍了php实现随机生成易于记忆的密码,实例分析了php生成随机密码的相关技巧,需要的朋友可以参考下
本文实例讲述了php实现随机生成易于记忆的密码。分享给大家供大家参考。具体实现方法如下:
这里通过预定义一些单词,让php随机从这些单词中选择进行组合生成密码
- function random_readable_pwd($length=10){
- // the wordlist from which the password gets generated
- // (change them as you like)
- $words = 'dog,cat,sheep,sun,sky,red,ball,happy,ice,';
- $words .= 'green,blue,music,movies,radio,green,turbo,';
- $words .= 'mouse,computer,paper,water,fire,storm,chicken,';
- $words .= 'boot,freedom,white,nice,player,small,eyes,';
- $words .= 'path,kid,box,black,flower,ping,pong,smile,';
- $words .= 'coffee,colors,rainbow,plus,king,tv,ring';
- // Split by ",":
- $words = explode(',', $words);
- if (count($words) == 0){ die('Wordlist is empty!'); }
- // Add words while password is smaller than the given length
- $pwd = '';
- while (strlen($pwd) < $length){
- $r = mt_rand(0, count($words)-1);
- $pwd .= $words[$r];
- }
- // append a number at the end if length > 2 and
- // reduce the password size to $length
- $num = mt_rand(1, 99);
- if ($length > 2){
- $pwd = substr($pwd,0,$length-strlen($num)).$num;
- } else {
- $pwd = substr($pwd, 0, $length);
- }
- return $pwd;
- }
- //使用范例:
- random_readable_pwd(10) => returns something like: pingwater6, radiohap28, sunwhite84, happykid44, etc...
希望本文所述对大家的php程序设计有所帮助。
