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。
