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
functionrandom_readable_pwd($length=10){ //thewordlistfromwhichthepasswordgetsgenerated //(changethemasyoulike) $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'; //Splitby",": $words=explode(',',$words); if(count($words)==0){die('Wordlistisempty!');} //Addwordswhilepasswordissmallerthanthegivenlength $pwd=''; while(strlen($pwd)<$length){ $r=mt_rand(0,count($words)-1); $pwd.=$words[$r]; } //appendanumberattheendiflength>2and //reducethepasswordsizeto$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)=>returnssomethinglike:pingwater6,radiohap28,sunwhite84,happykid44,etc...
希望本文所述对大家的php程序设计有所帮助。
