restore_include_path
If you find that this function is failing for you, and you're not sure why, you may have set your php include path in your sites's conf file in Apache (this may be true of .htaccess as well)
So to get it to work, comment out any "php_value include_path" type lines in your Apache conf file, and you should be able to set it now in your php code.
set_include_path
(PHP 4 >= 4.3.0, PHP 5)
set_include_path — include_path yönergesinin çalışma anı değerini belirler
Açıklama
string set_include_path
( string $yeni_değer
)
include_path yönergesinin, betiğin çalışma süresince geçerli olacak değerini belirler.
Dönen Değerler
Başarısızlık durumunda FALSE, aksi takdirde include_path yönergesinin eski değeriyle döner.
Örnekler
Örnek 1 - set_include_path() örneği
<?php
// PHP 4.3.0 ve sonrasında çalışır
set_include_path('/inc');
// PHP'nin tüm sürümlerinde çalışır
ini_set('include_path', '/inc');
?>
Örnek 2 - İçerilecek dosyaların aranacağı yollara bir yenisini eklemek
PATH_SEPARATOR sabitini kullanarak bu yolları işletim sisteminden bağımsız olarak çoğaltmak mümkündür.
Bu örnekte, include_path yönergesinde belirtilen dosya yollarına /usr/lib/pear dizinini ekleyeceğiz.
<?php
$path = '/usr/lib/pear';
set_include_path(get_include_path() . PATH_SEPARATOR . $path);
?>
Ayrıca Bakınız
- ini_set() - Bir yapılandırma yönergesine değer atar
- get_include_path() - include_path yönergesinin değerini döndürür
- restore_include_path() - include_path yönergesini eski değerine ayarlar
- include() - include

The files are included in order of the inclusion path, in this example, the directory structure is as follows:
.
|-- index.php
|-- t1
| |-- a
| `-- b
`-- t2
|-- b
`-- c
<?php
set_include_path('t1'.PATH_SEPARATOR.'t2');
include 'a'; // includes from T1
include 'b'; // includes from T1
include 'c'; // includes from T2
?>
Note that the include path affects only include/require functions.
<?php
var_dump(file_exists('a')); // false
var_dump(fopen('b', 'r')); // file not found
?>

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));
}
}
?>

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!
