Updating php website script

[NotionCommotion]

I am using PHP as a small embedded webserver on a RPi.  Similar to how apt-get updates packages, I desire a simple means to ensure that the PHP script (not the PHP version) is up to date.  I will be able to come up with some means to initiate whatever is needed to update the scripts (i.e. a shell script for the user, a cron job, etc).  Git is not installed and not desired.  Composer seems excessive for such a small site (but maybe is a good long term solution if it grows?).  I could just scp and replace it, but there is a text config file which shouldn't be overwritten.

 

Any recommendations?  Thank you

Could just have the PHP script update itself (or use another script).

file_put_contents(__FILE__, file_get_contents("wherever"));

Thanks requinix but doesn't address preventing the overwriting of site specific files (like the config file I described).  I obviously can read it into memory, overwrite all files, and then update anything that needs to be persistent, but thought there might be a smarter way to do so.

I think Requinix' response was spot on. You write the script that your installation then downloads and saves and then you transfer control to that "update" script to do whatever needs to be done, as you define it.

It sounds like you maybe want to do like composer does and create a phar file containing your PHP code then just update that when necessary. Stuff that shouldn't be overwritten would exist outside the phar file so it's not affected.
