Randomly generate four yards of English
//產生隨機碼，預設四碼，約七百次會出現碰撞
function get_random_key($length = 4)
{
$permitted_chars = '1234567890abcdefghijklmnopqrstuvwxyxABCDEFGHIJKLMNOPQRSTUVWXYX';
return substr(str_shuffle($permitted_chars), 0, $length);

I don't have time to shoot an introduction video, so I'll just grab some pictures and introduce the container environment deviny/phpenv I use. https://github.com/DevinY/phpenvphpenv can be regarded as an evolutionary version of my previous D-Laravel open source project, conceptually extending the use of many Dlaravel operation methods. The update of the container tends to be controlled by the user to build his own image, so I am not very good at changing the version number. In fact, the php version number of D-Laravel seems to have not been changed for a long time:p
I suddenly wanted to introduce what is WebShell, so I found one on the Internet. Its functions are quite good. But I still wanted some features, so I spent three nights making some small optimizations for him. If you haven't heard of WebShell yet, take a look at this video. If you like my optimized version, please give me a like, thank you.
Sometimes the ca file cannot be found due to PHP version update or environment change. fix is easy
