Is there a combination of application server and web server in php? Does lanmp belong?

first question:
the web server in lamp is apache, right? What about the application server? Is it php?

< hr >

question addition:
according to the following blog and StackOverflow Q & A, I found that in the lamp or lnmp stack, apache only calls php, through interfaces such as CGI,FastCGI,ISAPI, so my guess above is wrong. php is not an application server .
