创建大量用户时一个一个想密码是让人头疼的事,使用php随机生成一个安全可靠的密码,又方便又快捷,可以添加自己想的字符串,可以用在FTP密码、Mysql密码、网站

实现代码,复制即用:

header("Content-type:text/html;charset=utf-8");
function getRandPass($length = 6){
 $password = '';
 //将你想要的字符添加到下面字符串中,默认是数字0-9和26个英文字母
 $chars = "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";
 $char_len = strlen($chars);
 for($i=0;$i  $loop = mt_rand(0, ($char_len-1));
  //将这个字符串当作一个数组,,随机取出一个字符,并循环拼接成你需要的位数
  $password .= $chars[$loop];
 }
 return $password;
}
echo getRandPass(12); //随机生成一个12位数的密码

?>
