Is there a way to force a PHP script to bind to a prefixed IP?
Actually, while you can assign more IPs to Apache for listening, assigning
domains to specific IPs, it looks like any PHP script can freely choose
which IP to bind. Instead I'd love some domains are permitted to open
connections only from the domain IP.
In FreeBSD I do it easily, setting up dedicated jails for domains. But how
to do it simply using PHP on Linux?

1) Use Listen in Apache
2) Use VM such as KVM, VMWare, etc.
3) Make an array containing permissible domains. Check the
$_SERVER['SERVER_NAME'] if exists in that array. React/respond
accordingly.
1) is only for listening.
2) means a VPS for each domain, which we already do with vmware and
FreeBSD jails, but it is too expensive for some customers.
3) means I'm writing the script, which is not the standard situation.
You must suppose the script to be written from a malicious user in a
shared environment.
Is PHP able to 'force' binding IP? I hoped there was an external
directive I did not see, but probably this is a PHP lack.
