PHP safe string development ideas and code sharing

In our previous articles, we have always introduced to you how to intercept strings and convert strings. So today's course will introduce to you the development of PHP safe strings. Before that, When writing the cookie value, I looked at the cookie files of Google and Baidu. The value inside is a long string of characters.

$obj= new genRandomString();     //实例化类
$obj->len=&#39;30&#39;;                  //len 为自定义的字符长度
echo $obj->provideRandString();   //输出安全字符串

Finally run the file, the running result is as shown below:
