Q: Where can I learn more about PHP?
A: For more complete information you should consult the mSQL Web site at the PHP web site at http://php.net/

Q:  Can I use PHP with SSL?
A: At this time, PHP does not operate under SSL on our servers.

Q:  How can I use and install the CGI version of PHP?
A:  To install PHP as a CGI script, SSH to your Virtual Server and do the following:
% cd ~
% tar xvf /usr/local/contrib/php-2.0b12-msql-1.0.16.tar
This will install the php.cgi into the ~/www/cgi-bin directory for you to use.
If you would like more information on PHP, please visit the PHP web site at http://php.net/
NOTE: If you have FrontPage extensions installed on your Virtual Server and you use PHP, you must use PHP as a CGI script or your PHP will fail to function.

Q: Why is it necessary to use the CGI version of PHP with FrontPage extensions?
A: If you have FrontPage extensions installed on your Virtual Server and you use PHP, you must use PHP as a CGI script or your PHP will fail to function.
The reason is that during the installation of the FrontPage extensions, your web server was upgraded to Apache 1.2.4 which does not work with the compiled PHP module.

Q: How can I customize my version of PHP3 without access to a PHP.INI file?
A: We compile PHP directly into our Apache binary when we setup the Virtual Servers. As such you are able to specify any of the PHP statements normally placed in the php3.ini (PHP3) or php.ini (PHP4) file by using PHP directives in the Apache configuration files (~/www/conf directory) as long as the statement has been compiled into our PHP module.
Information on how to set this up is shown in greater detail on the PHP site at this URL:
http://www.php.net/manual/configuration.php3
Please note that with the newer version of PHP4 there are fewer statements you can utilize to make changes to the settings placed in the PHP module within the Apache binary.
If you wish to use older versions of PHP on your server you can do so by simply using the statements mentioned in "How can I use multiple versions of PHP?"
For a current list of modules installed within Apache, Telnet or SSH to your Virtual Server and enter the following command:
httpd –l
If you wish to see a list of the items installed within a specific module (for instance mod_php.c) you would type:
httpd -h | grep mod_php3.c
You should receive output similar to the following:
php3_error_reporting (mod_php3.c)
php3_doc_root (mod_php3.c)
php3_user_dir (mod_php3.c)
php3_safe_mode_exec_dir (mod_php3.c)
php3_include_path (mod_php3.c)
php3_auto_prepend_file (mod_php3.c)

As these are all customizations to your Virtual Server, we can only offer support in how to setup your server to parse your PHP pages. RSH Web Services Technical Support staff cannot support the customization of your PHP configurations, or specific modules on your Virtual Server.

Q:How can I use multiple versions of PHP?
A: You will need to place the following lines in the SRM.CONF file for each version of PHP:
#PHP4
AddType application/x-httpd-php .php4
####
#PHP3
AddType application/x-httpd-php3 .php3
Action application/x-httpd-php3 /cgi-bin/imap-php
#### 
#PHP2
AddType application/x-httpd-php2 .php2
Action application/x-httpd-php2 /cgi-bin/php.cgi
If you still cannot use PHP2 or PHP3, please Contact our Support Team. Please indicate whether you tried the above method.

Q: I can't get PHP 2 to work on my Virtual Server.
A: We've discovered that under our new BSDI 4 OS, php2 does not function correctly without some changes to the web configurations. The reason for this is due to the following lines in the srm.conf:
AddType application/x-httpd-php2  .phtml
Action application/x-httpd-php    /cgi-bin/php.cgi
Under the old system, Apache was compiled with PHP3. Our BSDI 4 systems have php4.0b2. As such, it is designed to respond to the application type x-httpd-php.
Thus, under the above configuration, even though you inform the Apache server to parse all .phtml pages using /cgi-bin/php.cgi, the mod_php4.0b2 thinks that the script should be parsed by the PHP4 interpreter, and the php2 code is interpreted as bad code.
The solution? Change the configuration in the srm.conf (or .htaccess, if applicable) to the following:
AddType application/x-httpd-php2   .phtml
Action application/x-httpd-php2    /cgi-bin/php.cgi
