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 — Modifie la valeur de la directive de configuration include_path
Description
string set_include_path
( string $new_include_path
)
Modifie la valeur de la directive de configuration include_path, pour la durée du script en cours.
Liste de paramètres
- new_include_path
-
La nouvelle valeur pour la directive de configuration include_path
Valeurs de retour
Retourne l'ancienne valeur de include_path en cas de succès, et FALSE si une erreur survient.
Exemples
Exemple #1 Exemple avec set_include_path()
<?php
// Fonctionne depuis PHP 4.3.0
set_include_path('/inc');
// Fonctionne sur toutes les versions
ini_set('include_path', '/inc');
?>
Exemple #2 Ajout dans le chemin d'inclusion
En utilisant la constante PATH_SEPARATOR, il est possible d'étendre le chemin d'inclusion au vu du système.
Dans cet exemple, nous ajoutons /usr/lib/pear à la fin de l'actuel include_path.
<?php
$path = '/usr/lib/pear';
set_include_path(get_include_path() . PATH_SEPARATOR . $path);
?>

Can be useful to check the value of the constant PATH_SEPARATOR.
<?php
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

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!
