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... |
