<function>Apache_note</function> is an Apache-specific function
|
|
which gets and sets values in a request's
|
|
<literal>notes</literal> table. If called with one argument, it
|
|
returns the current value of note
|
|
<literal>note_name</literal>. If called with two arguments, it
|
|
sets the value of note <literal>note_name</literal> to
|
|
<literal>note_value</literal> and returns the previous value of
|
|
note <literal>note_name</literal>.

You can also get at the value of the common CGI variables by

reading them from the environment, which works whether or not
|
|
you are using PHP as an Apache module. Use
|
|
<function>phpinfo</function> to see a list of all of the
|
|
environment variables defined this way.

<para>

|
<function>Virtual</function> is an Apache-specific function which
|
|
is equivalent to <!--#include virtual...--> in mod_include.
|
|
It performs an Apache sub-request. It is useful for including
|
|
CGI scripts or .shtml files, or anything else that you would
|
|
parse through Apache. Note that for a CGI script, the script
|
|
must generate valid CGI headers. At the minimum that means it
|
|
must generate a Content-type header. For PHP files, you need to
|
|
use <function>include</function> or <function>require</function>;
|
|
<function>virtual</function> cannot be used to include a document
|
|
which is itself a PHP file.
