I'm running Apache on Mac, PHP is installed, and I suspect something in the httpd.conf is not correctly set.
The symptom: Running PHP files in localhost yields PHP code, nothing else.
Running apachectl -D DUMP_HOSTS
yields:
Permission denied: make_sock: could not bind to address [::]:80 (13)Permission denied: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down Unable to open logs
Help.
