這篇文章主要介紹了php實現隨機生成易于記憶的密碼,實例分析了php生成隨機密碼的相關技巧,需要的朋友可以參考下
本文實例講述了php實現隨機生成易于記憶的密碼。分享給大家供大家參考。具體實現方法如下:
這里通過預定義一些單詞,讓php隨機從這些單詞中選擇進行組合生成密碼
- 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...
希望本文所述對大家的php程序設計有所幫助。
