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。
