Overwrite php builtin functions?

Question

How to overwrite php default/builtin functions like gethostname(), die() etc..?

if we call a php function gethostname like echo gethostname(); it will return localhost or whatever the host of the machine is. Instead of that, I want to pass hostname as host1.

I want to pass a custom host name whenever gethostname is called.

Download the PHP source code written in C, make changes you need, compile, done. — marekful, Jun 05 '18 at 13:46

Also note that you would need to repeat this process every time a new PHP version is released. This sounds like an [x-y problem](http://xyproblem.info/) though. — Loek, Jun 05 '18 at 13:50
It's probably **way** easier to just rename your host in Apache's httpd-vhosts.conf file... — CD001, Jun 05 '18 at 13:55

You could override the function and write the functionality on your own:
