The PHP4 CGI
The PHP CGI is a free-standing PHP interpreter. While this makes PHP available through
the command line, it is less efficient than the PHP Apache Module.
Installation
To install the PHP4 CGI, connect to your Virtual Private Server via Telnet
or SSH and do the following.
-
Install the PHP4 CGI by running the following command:
% vinstall php4-cgi
When you run the vinstall command, you will be given the option to select which extensions you want to use.
In order to not waste memory on your Virtual Private Server, we recomend that you only select extensions you will
actually be using. If you find you need to add or remove extensions at a later time, you can manually edit the
php.ini file, or use the vinstall command to change the active extensions.
|
NOTE: Any version prior to PHP4.2.2 has a known security vulnerability which can compromise your
Virtual Private Server. If you are using a version of PHP prior to 4.2.2, we strongly encourage you to
upgrade to the most recent version.

-
Due to Security Issues the PHP4 CGI is installed at
~/usr/local/bin/php. Do the following to link the PHP4 CGI into your ~/www/cgi-bin directory.
% cd ~/www/cgi-bin
% ln ../../../bin/php.cgi php
-
Make the following additions and modifications to your web server configuration file
(~/www/conf/httpd.conf).
-
Modify the DirectoryIndex line so that PHP4 files will be included as directory indices.
DirectoryIndex index.php index.php4 index.php3 index.cgi index.html index.htm
-
Add the following lines so that all files with .php, .php3, .php4, and .phtml
extensions will be redirected to the PHP4 CGI executable.
Action php4-script /cgi-bin/php
AddHandler php4-script .php .php3 .php4 .phtml
-
Restart your Web Server by running the restart_apache command.
-
To test your PHP installation, try creating the following ~/www/htdocs/test.php4 document and viewing it
in your web browser.
<HTML>
<BODY>
<?php
phpinfo();
?>
</BODY>
</HTML>
The phpinfo() function reports the version number, as well as the features that are compiled into
PHP.
