Is there a PHP HTTP reverse shell? I haven't been able to find one, only ones that transmit using TCP packets (not HTTP).
Note, I mean actually using HTTP packets as the C2, not just transmitting TCP packets over port 80.
Metasploit just has: payload/php/meterpreter/reverse_tcp
and a few variations of that.
For Windows, Metasploit has windows/meterpreter/reverse_http
but again, nothing for PHP.
