php实现随机生成易于记忆的密码

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) 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...
