超级简单的随机字符串生成器-用于密码

Posted 2021-02-25

I needed a way to generate some random strings for passwords, a number of methods seemed a little over the top so below is my simplified version that does the trick. I have set it to use non-confusing characters, so no i's, l's, 0's but very easy to change.

<?php 
 
/*
* str_shuffle to generate a random series of characters based on those provided, uniqid added, then shuffled again.
* substr will trim the output down to between 10 and 12 characters randomly. 
*/
 
//Generate 10 Random Strings
$i = 1;
while($i <= 10){
echo substr(str_shuffle(uniqid(str_shuffle("abcdefghjkmnpqrstwxyzABCDEFGHJKMNPQRSTWXYZ23456789"))), 0, rand(10,12))."<br/>";
$i++;
}
 
?>
