Help -- Pear Installation problems

Hi -- This is a very weird problem. I couldn't find anybody else with this. Maybe someone can help. I downloaded the gopear script. I listed it below. I accessed it with http://localhost/gopear.php and it didn't execute, it just displayed the script in the browser. I went to the command prompt and typed php gopear.php and the results were identical to issuing TYPE GOPEAR.PHP. I am using php vers 4.3.7. I can go to my basic script: http://localhost/hello.php and it works fine -- "Hello World" plus phpinfo() Thanks in advance for any help. Monique. *** LISTING OF GOPEAR.PHP <?php //; echo; echo "YOU NEED TO RUN THIS SCRIPT WITH PHP NOW!"; echo; echo "Try this: lynx -source http://pear.php.net/go-pear | php -q"; echo; exit # -*- PHP -*- # +----------------------------------------------------------------------+ # | PHP Version 5 | # +----------------------------------------------------------------------+ # | Copyright (c) 1997-2004 The PHP Group | # +----------------------------------------------------------------------+ # | This source file is subject to version 2.02 of the PHP license, | # | that is bundled with this package in the file LICENSE, and is | # | available at through the world-wide-web at | # | http://www.php.net/license/2_02.txt. | # | If you did not receive a copy of the PHP license and are unable to | # | obtain it through the world-wide-web, please send a note to | # | license@php.net so we can mail you a copy immediately. | # +----------------------------------------------------------------------+ # | Authors: Tomas V.V.Cox <cox@idecnet.com> | # | Stig Bakken <ssb@php.net> | # | Christian Dickmann <dickmann@php.net> | # | Pierre-Alain Joye <pajoye@pearfr.org> | # | Greg Beaver <cellog@php.net> | # +----------------------------------------------------------------------+ # $Id: go-pear,v 1.71 2004/10/25 04:18:17 cellog Exp $ # # Automatically download all the files needed to run the "pear" command # (the PEAR package installer).

It is # still beta codes, but feel free to test it: # 1.: Download the go-pear script by using the "Save target as ..." function # of your browser here. # # 2.: Place the go-pear file somewhere under the document root of your webserver. # The easiest way is to create a new directory for pear and to put the file in there. # Be sure your web server is setup to recognize PHP, and that you use an appropriate # extension. For example, you might name this file gopear.php # # 3.: Access go-pear through your webserver and follow the instructions. Please # make sure that PHP has write access to the dir you want to install PEAR into. # For example: http://localhost/pear/gopear.php # # 4.: After running go-pear you get a link to the Web Frontend of the PEAR installer. # I suggest bookmarking this link. # # 5.: Protect the Web Frontend directory and the go-pear script with a password. # Use .htaccess on Apache webservers for example. # # $sapi_name = php_sapi_name(); set_time_limit(0); @ob_end_clean(); ob_implicit_flush(true); define('WEBINSTALLER', ($sapi_name != 'cli' && !(substr($sapi_name,0,3)=='cgi' && !isset($_SERVER['GATEWAY_INTERFACE'])))); ini_set('track_errors', true); ini_set('html_errors', WEBINSTALLER); ini_set('magic_quotes_runtime', false); error_reporting( E_ALL & ~E_NOTICE); define('WINDOWS', (substr(PHP_OS, 0, 3) == 'WIN')); define('GO_PEAR_VER', '0.5.0'); define('WIN32GUI', !WEBINSTALLER && WINDOWS && $sapi_name=='cli' && which('cscript')); /* * See bug #23069 */ if ( WEBINSTALLER && WINDOWS ) { $php_sapi_name = win32DetectPHPSAPI(); if($php_sapi_name=='cgi'){ $msg = nl2br(" Sorry!
