WeberDev.com -> PHP Manual -> Get and set apache request notes

Description

string apache_note ( string $note_name [, string $note_value ] )

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.

Parameters

note_name: The name of the note.
note_value: The value of the note.

Return Values

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.

Examples

 <?php

apache_note('name', 'Fredrik Ekengren');

$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);
