Пример #1 set_include_path() example


<?php
// Works as of PHP 4.3.0
set_include_path('/usr/lib/pear');

// Works in all PHP versions
ini_set('include_path', '/usr/lib/pear');
?>

Пример #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);
?>

ini_set() - Sets the value of a configuration option
get_include_path() - Gets the current include_path configuration option
restore_include_path() - Restores the value of the include_path configuration option
include()
