Does .php exist?

No. No — .php is a programming file extension, not a TLD.

The full story

Like .html and .exe, .php exists only as a file suffix. No TLD application was ever filed for it.

What to use instead

.dev — Best value in domains for anything developer-facing.sh — The shell-script TLD

Wondering about another extension? Every real TLD is in the directory.
