Hi all,
I'm been writing Bash script for a while now, and I use it for most of the Linux servers.
My current workplace is currently using PHP to maintain web servers.
So I'm try to learn PHP by write PHP scripts for my servers.
I wrote this script for my Nextcloud server, and I would like to know if there is room for improvement.
I tried to use curl to check for header but it didn't work.
Therefore, I'm using wget module instead.
Thanks
