running=$(/bin/launchctl print system/org.apache.httpd 2>/dev/null)

if [[ -z "$running" ]] && [[ -z "$enabled" ]]; then

Discussion

The built-in web server is a non-essential service built into macOS and _MUST_ be disabled.

NOTE: The built in web server service is disabled at startup by default macOS.
