Sets the include_path configuration option
string set_include_path ( string $new_include_path )

Parameters:
new_include_path
The new value for the include_path
Returns:
Returns the old include_path on success or FALSE
on failure.
Examples:
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'); ?>
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); ?>
