set_include_path

(PHP 4 >= 4.3.0, PHP 5, PHP 7)

set_include_path — Sets the include_path configuration option

set_include_path ( string $new_include_path ) : string|false

Sets the include_path configuration option for the duration of the script.

Returns the old include_path on success or FALSE on failure.

Example #1 set_include_path() example

<?phpset_include_path('/usr/lib/pear');// Or using ini_set()ini_set('include_path', '/usr/lib/pear');?>

Example #2 Adding to the include path

Making use of the PATH_SEPARATOR constant, it is possible to extend the include path regardless of the operating system.

In this example we add /usr/lib/pear to the end of the existing include_path.

<?php$path = '/usr/lib/pear';set_include_path(get_include_path() . PATH_SEPARATOR . $path);?>
