$note_name
) : string$note_name
, string $note_value
) : string
This function is a wrapper for Apache's table_get
and
table_set
. It edits the table of notes that exists
during a request. The table's purpose is to allow Apache modules to
communicate.
The main use for apache_note() is to pass information from one module to another within the same request.
note_name
The name of the note.
note_value
The value of the note.
If called with one argument, it returns the current value of note
note_name
. If called with two arguments, it
sets the value of note note_name
to
note_value
and returns the previous value of
note note_name
.
If the note cannot be retrieved, FALSE
is returned.
Example #1 Passing information between PHP and Perl
<?php
apache_note('name', 'Fredrik Ekengren');
// Call perl script
virtual("/perl/some_script.pl");
$result = apache_note("resultdata");
?>
# Get Apache request object my $r = Apache->request()->main(); # Get passed data my $name = $r->notes('name'); # some processing # Pass result back to PHP $r->notes('resultdata', $result);
Example #2 Logging values in access.log
<?php
apache_note('sessionID', session_id());
?>
# "%{sessionID}n" can be used in the LogFormat directive
