Find out how PHP is running on server (CGI OR fastCGI OR mod_php)

by

That’s the Server API row on top of phpinfo()’s output:

Server API: Apache 2.0 Handler + CGI/FastCGI

However, please note that it won’t necessarily tell you the exact version of Apache or the exact CGI handler. It just describes the SAPI in use.

You can also call the php_sapi_name() function (or the PHP_SAPI constant, which provides the same info):

Description

string php_sapi_name ( void )

Returns a lowercase string that describes the type of interface (the
Server API, SAPI) that PHP is using. For example, in CLI PHP this
string will be “cli” whereas with Apache it may have several different
values depending on the exact SAPI used

It’s still a good idea to check your HSP’s documentation because it possible to have several PHP versions available.

Remember you need to run phpinfo() from the same environment you want to check (web server won’t tell you about command line and vice-versa):

C:\>php -i | findstr /C:"Server API"
Server API => Command Line Interface

$ php -i | grep 'Server API'
Server API => Command Line Interface
