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
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23
24
25
26

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...
