Hi Phil,
Adding to what Ado said, the php code $_SERVER['SERVER_NAME'] allows you to
define 'SERVER_NAME' = 'my_development_server_name' in a config file, so you
only have to type this once. This is what makes php transportable, since the
config file is the only one you need to change when moving from server to
server. Similarly, the location of your mySql server and connection details
are defined just once. Everything flows on from there, since folder names
refer to the server, and file names to the folder etc.
Like you, I decided to develop my own php site armed with a fair bit of
expertise with HTML and databases, and one year later I'm still at it! My
site is very complex, with 800 pages, but I'm only customising proprietary
software, and it's been the steepest learning curve I've ever been on.
I strongly recommend you seek out some online tutorials before you begin,
firstly on installing and configuring Linux/Apache/mySql and php, which is
no mean feat, then on building a website with php and mySql. There are lots
of good ones around, and they will save weeks, maybe months of frustration.
Bear in mind it's all OpenSource, so although there are manuals, they're not
written with customer service in mind. Nor are there any simple editing
tools for these programs as there are for HTML, and just to make things
really difficult, it's not possible to see the source code of web pages
you'd like to emulate. I mistakenly thought it would be like learning
Javascript, but after trawling through countless sites looking for code
snippets that either don't work or cost money, I think the best (only) place
to see examples of working scripts is at koders.com.
One final tip - try and choose a hosting service that can offer some support
with php code. I'm at quadrahosting.com and they've been brilliant.
Cheers,
Jem
