Recipe 16.9 Localizing Included Files
16.9.1 Problem
You want to
include
locale-specific files in your pages.
16.9.2 Solution
Dynamically modify the include_path once
you've determined the appropriate locale:
$base = '/usr/local/php-include';
$LANG = 'en_US';
$include_path = ini_get('include_path');
ini_set('include_path',"$base/$LANG:$base/global:$include_path");
16.9.3 Discussion
The $base variable holds the name of the base
directory for your included localized files. Files that are not
locale-specific go in the global subdirectory of
$base, and locale-specific files go in a
subdirectory named after their locale (e.g.,
en_US). Prepending the locale-specific directory
and then the global directory to the include path makes them the
first two places PHP looks when you include a file. Putting the
locale-specific directory first ensures that nonlocalized information
is loaded only if localized information isn't
available.
This technique is similar to what the img( )
function does in the Section 16.8. Here,
however, you can take advantage of PHP's
include_path feature to have the directory
searching happen automatically. For maximum utility, reset
include_path as early as possible in your code,
preferably at the top of a file loaded via
auto_prepend_file on every request.
