Event On Subdomain is added

I need to be notified when a client has added a subdomain or removed it,
Is there ant way to add a php script or other language on that event?

Any help will be much apperciated.

subdomain_create_pre.sh - Runs BEFORE a subdomain is created, but after it's confirmed. If this script returns a non-zero value, the creation is aborted.
subdomain_create_post.sh - Runs AFTER the subdomain is created.
subdomain_destroy_pre.sh - Runs BEFORE a subdomain is destroyed. If this script returns a non-zero value, the destruction is aborted
subdomain_destroy_post.sh - Runs AFTER the subdomain is destroyed.
