# LII. Net_Gopher

# Introduction

The gopher protocol, as defined by RFC 1436, is generally considered the ancestor of the modern HTTP protocol. However, gopher was also intended to provide references to non-gopher resources including telnet, wais, nntp, and even http. This extension adds gopher support to PHP's URL Wrappers, and provides a helper function gopher_parsedir() to make sense of gopher formatted directory listings.

# Requirements

# Installation

Net_Gopher is installed through the usual PECL package installation process.

- Prerequisite: PHP 4.3.0.

-     $ pear install Net_Gopher

- Copy the resulting `gopher.so` to an appropriate location and add extension=gopher.so to your `php.ini` file or load it dynamically in your PHP script using dl("gopher.so");
