php实现随机生成易于记忆的密码

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。
