If you got your domain account with Cruzio prior to July of 2006,
then you probably have a 'Classic' domain. This page has information
that applies to your style of domain account.
PHP is a simple yet powerful language designed for creating HTML
content. Initially launched by Rasmus Lerdorf in 1995, PHP quickly
gained popularity largely due to its ease of use.
All servers hosting domains should be PHP and MySQL enabled by
the end of October.
PHP development is now sponsored by the Apache
Software Foundation. Like many other vital Internet
technologies, PHP is free software, maintained
and improved by a number of volunteers from across
the globe.
PHP stands
for Personal Home Page. The name reflects the original intent,
which was to create some simple tools to perform tasks important
to most Web developers. For example, PHP can turn log data
about site visitors to into a nice, easy to read Web page.
PHP pages are HTML pages with PHP commands
embedded in them. The Web server processes the PHP commands
and sends the output to the browser. It's popularity is due
to its ease of use-- you don't have to be a programmer to
get PHP to perform tasks a script would ordinarily do.
PHP is installed
on all Cruzio Web servers hosting custom domains. Any valid
PHP command embedded into the pages you've uploaded to your
Web space will be processed by the server, so long as the
file extension is .phtml or .php
Cruzio has
PHP running in safe mode. Since PHP scripts running on a particular
server don’t distinguish between different users, running
PHP in safe mode prevents other users from seeing your data
files. Safe mode imposes the following measures:
PHP looks at the owner of a script
and runs it only as that user.
Any file operation checks to see if
the affected file or directory is owned by the same user
as the PHP script.
Any system call can only access executables
located in the designated directory associated with an account.
Data not generated from within your
user environment is considered insecure. To put it more
succinctly, the register_globals function is disabled.
Safeguards to prevent cross-user file
overwriting, password detection, etc.
PHP
has support for over 20 databases both open source and commercial.
You can use PHP to access a database hosted elsewhere on the
Internet or create a MySQL database at Cruzio.
Cruzio provides MySQL database servers
for use by custom domain accounts. You can easily create
and administer a MySQL database from your custom domain control
panel.
PHP commands embedded into your HTML pages
can be used to connect to the database, issue a query and
display the results in a browser. The database may be queried
from anywhere on the Internet, not just from files hosted
on Cruzio servers.
For more information about using PHP with
databases, please check out our Resources
section.
7. Can
I use both SSI and PHP scripts within the same file?
No,
you can make only one type of server call from a given file,
either a server-side include (SSI) or PHP. The server will
automatically process .html files containing SSIs, but files
containing PHP scripts must be named with the .phtml or .php
extension.
Cruzio is responsible
for ensuring that the systems which allow you access to PHP
and other account features, are up and operational. Cruzio does
not provide instruction in Web development. To learn more about
using PHP, check out our Resources
section. Our list of Consultants
may also prove helpful.
