Page 1 Introducing PHP and MySQL
Unless you've been living on Mars for the last six to eight
months, you've heard of open source software (OSS). This movement
has got so much momentum that even the big boys are taking
notice. Companies like Oracle, Informix, and a host of others
are releasing their flagship database products for that poster
child of the OSS movement, Linux.
Having a massively complex RDBMS (relational database management
system) is all well and good if you know what to do with it.
But perhaps you are just getting into the world of databases.
You've read Jay's article and you want to put up your own
data-driven Web site. But you find you don't have the resources
or desire for an ASP server or some pricey database. You want
something free, and you want it to work with Unix.
Enter PHP and MySQL. These two make up what must be the best
combination for data-driven Web sites on the planet. You needn't
take my word for it. An unofficial Netcraft survey shows that
PHP usage has jumped from 7,500 hosts in June 1998 to 410,000
in March 1999. That's not bad. The combination was also awarded
Database of the Year at Webcon98, where it received a lovely
tiara.
MySQL is a small, compact database server ideal for small
- and not so small - applications. In addition to supporting
standard SQL (ANSI), it compiles on a number of platforms
and has multithreading abilities on Unix servers, which make
for great performance. For non-Unix people, MySQL can be run
as a service on Windows NT and as a normal process in Windows
95/98 machines.
PHP is a server-side scripting language. If you've seen ASP,
you'll be familiar with embedding code within an HTML page.
Like ASP, PHP script is processed by the Web server. After
the server plays with the PHP code, it returns plain old HTML
back to the browser. This kind of interaction allows for some
pretty complex operations.
In addition to being free (MySQL does have some licensing
restrictions though), the PHP-MySQL combination is also cross-platform,
which means you can develop in Windows and serve on a Unix
platform. Also, PHP can be run as an external CGI process,
a stand-alone script interpreter, or an embedded Apache module.
If you're interested, PHP also supports a massive number
of databases, including Informix, Oracle, Sybase, Solid, and
PostgreSQL - as well as the ubiquitous ODBC.
PHP supports a host of other features right at the technological
edge of Internet development. These include authentication,
XML, dynamic image creation, WDDX, shared memory support,
and dynamic PDF document creation to name but a few. If that's
not enough, PHP is easy to extend, so you can roll your own
solution if you're programming savvy.
Finally, since both efforts are collaborative in nature,
there's always plenty of support from documentation and mailing
lists. Bugs are fixed rapidly, and requests for features are
always heard, evaluated, and if feasible, implemented.
Enough talk! Let's go over what we're going to cover in this
tutorial.
Lesson 1 is going to cover the installation of these products
on both Unix and Windows systems. If you don't need to worry
about that (you're working on your ISP's machine, perhaps),
jump right to the first example scripts, where the magic starts.
In Lesson 2 we'll look at some more complex scripting goodies,
including looping, form input, and sending data from and to
the database.
Lesson 3 will cover validation and techniques for making
your PHP scripts smart and clean.
Let's roll.
