YP/NIS Functions
Introduction
NIS (formerly called Yellow Pages) allows network management of important administrative files (e.g. the password file). For more information refer to the NIS manpage and » The Linux NIS(YP)/NYS/NIS+ HOWTO. There is also a book called » Managing NFS and NIS by Hal Stern.
Note: This extension has been moved to the » PECL repository and is no longer bundled with PHP as of PHP 5.1.0.
Note: This extension is not available on Windows platforms.
Requirements
None besides functions from standard Unix libraries which are always available (either libc or libnsl, configure will detect which one to use).
Installation
To get these functions to work, you have to configure PHP with --enable-yp.
Runtime Configuration
This extension has no configuration directives defined in php.ini.
