<title>CGI and command line setups</title>
<para>
By default, PHP is built as both a <acronym>CLI</acronym> and
<acronym>CGI</acronym> program, which can be used for CGI
processing. If you are running a web server that PHP has module
support for, you should generally go for that solution for
performance reasons. However, the CGI version enables users to run
different PHP-enabled pages under different user-ids.

<sect2 xml:id="install.unix.commandline.testing">
<title>Testing</title>
<simpara>
If you have built PHP as a CGI program, you may test your build
by typing <command>make test</command>. It is always a good idea
to test your build. This way you may catch a problem with PHP on
your platform early instead of having to struggle with it later.

Some <link linkend="reserved.variables.server">server supplied
environment variables</link> are not defined in the
current <link xlink:href="&url.cgispec;">CGI/1.1 specification</link>.
Only the following variables are defined there: <varname>AUTH_TYPE</varname>,
<varname>CONTENT_LENGTH</varname>, <varname>CONTENT_TYPE</varname>,
<varname>GATEWAY_INTERFACE</varname>, <varname>PATH_INFO</varname>,
<varname>PATH_TRANSLATED</varname>, <varname>QUERY_STRING</varname>,
<varname>REMOTE_ADDR</varname>, <varname>REMOTE_HOST</varname>,
<varname>REMOTE_IDENT</varname>, <varname>REMOTE_USER</varname>,
<varname>REQUEST_METHOD</varname>, <varname>SCRIPT_NAME</varname>,
<varname>SERVER_NAME</varname>, <varname>SERVER_PORT</varname>,
<varname>SERVER_PROTOCOL</varname>, and <varname>SERVER_SOFTWARE</varname>.
Everything else should be treated as 'vendor extensions'.
