范例

Example#1 set_include_path() example

<?php
// Works as of PHP 4.3.0
set_include_path('/inc');

// Works in all PHP versions
ini_set('include_path''/inc');
?>

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);
?>
