php实现随机生成易于记忆的密码

2015-06-19 16:10 766 查看

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。
