PHP info
We provide both php3 and php4 to virtual clients. Any file
with the extension with .htm will use php3. If the file
extension is .cgi, then you can use php3 or 4. With the .cgi
files, the first line of your code must contain the path to
php. Here are examples for php3 and php4 respectively:
#!/usr/bin/php
#!/usr/bin/php4
One of these must be the first line of the script. On top of
that, you must make sure that the file permissions are also
set correctly.
You can see some information on our php3 and 4
configurations using the following code
Place this link into a php file: <?php phpinfo(); ?>
This will give you up-to-date information for php on your
server.
Connecting to MySQL through PHP
Use the following outline to connect and begin querying the
mySQL server from within your PHP scripts. Remember that you
cannot connect to your databases remotely due to security
reasons. You can only connect to them form local host.
1. Connect To The mySQL Server
Use the following statement to connect to the database
server. Substitute the username, and password for ones who
have created in the MyAdmin interface and have given
adequate permissions to this database.
MYSQL_CONNECT('localhost','USERNAME',' PASSWORD');
2. Select Your Database
Use the following statement to select the database you
wish to connect to. Make sure you substitute the example
with your database name.
@mysql_select_db("DATABASE NAME");
3. Executing A Query
You are now ready to execute your queries. Remember that the
databases and users used must be created in the MyAdmin
interface in your PCP. Most problems that arise with your
scripts will be due to incorrect permission settings.

running this as an apache module, then you do not need this
line.
Can I use PHP in Conjunction with MySQL?
Absolutely. Once of the big advantages of PHP is the ability
to interface to databases, including mySQL. Since we offer
mySQL as apart of our service, you can have PHP act as a
front-end to your mySQL databases.
Not only is this possible, but it is very powerful. Many of
the applications, such as parts of webhosting-support.com,
are provided as PHP output querying from a mySQL database.

information.

directory and will run anywhere on your virtual server.

What is PHP?
PHP is a server-side, cross-platform, HTML embedded
scripting language. It has a syntax familiar to both Perl
and C. PHP-enabled web pages are treated just like regular
HTML pages and you can create and edit them the same way you
normally create regular HTML pages.
What are valid file extensions I can use
for PHP scripts?
The valid file extensions for PHP scripts are listed below:
.htm3 .htm These file extensions must be used in order for
your PHP scripts to run properly.
What permissions do I need to use on my
PHP scripts?
To avoid any problems, you should set your PHP scripts to
755, or user everything, group and world read and execute
permission.
What userid does my PHP scripts run
under?
Your PHP scripts will run under the same userid as the web
server (Apache), which is "nobody". Therefore, since your
PHP scripts do not run under your userid, you must take this
into consideration when you are trying to create, edit, or
modify files with your PHP scripts. Secondly, PHP scripts
run under the group "nobody" as well. All clients are in the
group "cust". Therefore, in order to allow PHP to create,
modify, and/or delete files within your account, you would
need to have world read/write permission on the files and
within the directories where the files will be created.
Why won't my PHP scripts
create/edit/delete files?
This is because your PHP scripts run under the userid
"nobody" and group "nobody". In order to get around this,
you will need to set the relevant files and directories to
world read/writeable.
