Please do not submit the same bug more than once. An existing
bug report already describes this very problem. Even if you feel
that your issue is somewhat different, the resolution is likely
to be the same.
Thank you for your interest in PHP.

Description:
------------
I would like to start an instance of the FastCGI interpreter which
listens to a Unix Domain socket. libfcgi would this, but the wrapper
code in cgi_main.c differentiates only between
php4-cgi -b $ADDRESS:$PORT
and
php4-cgi -b [:]$PORT
If the colon is missing, it is assumed that the user wants a TCP socket
which is not bound to a specific address and thus a colon is prepended.
This breaks passing a path to a Unix Domain socket.
Fix: Since libfcgi apparently accepts the port only in numeric form
anyhow, I have simply added a check whether the first character of the
argument is a digit. In this case, it is assumed to be a port and
prepended with a colon. If not, it is assumed to be a pathname.
Alternatively, one could altogether remove the code which prepends the
colon and document the behavior.

Actual result:
--------------
bengen@ataraxia:~$ php4-cgi -b /tmp/foo
bind/listen: No such file or directory
Couldn't create FastCGI listen socket on port /tmp/foo
bengen@ataraxia:~$ echo $?
