restore_include_path
Two functions to help:
<?php
function add_include_path ($path)
{
foreach (func_get_args() AS $path)
{
if (!file_exists($path) OR (file_exists($path) && filetype($path) !== 'dir'))
{
trigger_error("Include path '{$path}' not exists", E_USER_WARNING);
continue;
}
$paths = explode(PATH_SEPARATOR, get_include_path());
if (array_search($path, $paths) === false)
array_push($paths, $path);
set_include_path(implode(PATH_SEPARATOR, $paths));
}
}
function remove_include_path ($path)
{
foreach (func_get_args() AS $path)
{
$paths = explode(PATH_SEPARATOR, get_include_path());
if (($k = array_search($path, $paths)) !== false)
unset($paths[$k]);
else
continue;
if (!count($paths))
{
trigger_error("Include path '{$path}' can not be removed because it is the only", E_USER_NOTICE);
continue;
}
set_include_path(implode(PATH_SEPARATOR, $paths));
}
}
?>
set_include_path
(PHP 4 >= 4.3.0, PHP 5)
set_include_path — Establece la opción de configuración include_path
Descripción
string set_include_path
( string $nueva_ruta_inclusion
)
Establece la opción de configuración include_path durante la duración del script.
Valores retornados
Devuelve el valor antiguo de include_path en caso de éxito, o FALSE en caso de fallo.
Ejemplos
Example #1 Ejemplo de set_include_path()
<?php
// Funciona a partir de PHP 4.3.0
set_include_path('/inc');
// Funciona en todas las versiones de PHP
ini_set('include_path', '/inc');
?>
Example #2 Añadir a la ruta de inclusión
Haciendo uso de la constante PATH_SEPARATOR es posible extender la ruta de inclusión independientemente del sistema operativo.
En este ejemplo agregamos /usr/lib/pear al final del valor include_path actual.
<?php
$ruta = '/usr/lib/pear';
set_include_path(get_include_path() . PATH_SEPARATOR . $ruta);
?>

a hint to the note of anonymous and in general: you can use relative paths instead of such a complex construct, sothat you do not need to use values from out of your scripts boundaries. those values you should at best never trust.

If you are using a CGI install you cannot use the htaccess solution. You could try something like this:
$user = preg_match('/\/([\w]+)\/www\//', __FILE__, $matches);
$user = $matches[1];
$path = "/u/$user/includes";
set_include_path(get_include_path() . PATH_SEPARATOR . $path);

Can be useful to check the value of the constant PATH_SEPARATOR.
if ( ! defined( "PATH_SEPARATOR" ) ) {
if ( strpos( $_ENV[ "OS" ], "Win" ) !== false )
define( "PATH_SEPARATOR", ";" );
else define( "PATH_SEPARATOR", ":" );
}
For older versions of php, PATH_SEPARATOR is not defined.
If it is so, we must check what kind of OS is on the web-server and define PATH_SEPARATOR properly

Just a note on koenig at electronova dot net's post:
to be OS independent you'd use '.PATH_SEPARATOR.'

Not shure if it is possible to use wildchars when setting include_path in php.ini [for example include_path=.:/usr/lib/php:/home/*/includes ].

You can also add several paths in one set_include_path separating them by ':'.
ex : set_include_path('/home/mysite/includes1:/home/mysite/includes2')

When you use .htaccess to set the include path, don't forget Apache directive 'AllowOverride Options' or 'AllowOverride All' is also needed.

In order to use .htaccess files to set the include path, PHP must be installed as an Apache module. If PHP is compiled as a CGI binary, you can set the include path in a custom php.ini file (if, for example, you're being hosted somewhere and don't have access to the main php.ini file. Note that custom php.ini files don't affect subdirectories in the way that .htaccess files do, so you'll need to put your custom php.ini file in any subdirectories as well.

If you want to set the paths php uses to find included files on a directory by directory level, you can do so in Apache's .htaccess file. Add the line:
php_value include_path "<first path to look>:<second path>:<etc>:."
to the .htaccess file. This will replace any paths set in your environment or the php.ini file so remember to include the path to php's own libraries as, usually, the first option!
