Introduction to apache virtual host WML, Apache, and PHP

In the company's website, I found that I needed a wireless website that could receive my emails, stock market information, etc. I didn't want to pay people to get the information I wanted, so I decided to develop a wireless website. Such information is on the Internet. It's okay, but it's so scattered that it's difficult to collect. I need to be able to execute php, access the database, and I need PHP to do other functions for me. This article covers the basics of wml, how to set up your apache server and php. These basics allow you to build an environment and learn future applications by yourself.
Requirements
You need to have some experience with Apache Web Server, Php and html. For system requirements, I use apache 1.3.9, php3, and Red Hat Linux 6.0 for demonstration. I haven't encountered any problems running Apache on Windows, and PHP3 or PHP4.
In this article, I will guide you in the areas of contact: Introduction to wml, setting up wireless on Apache applications, and create your first WML/PHP web page. Most of the information can be gathered from the Internet.
Introduction to WML
WML stands for Wireless Markup Language. WAP phones or similar devices are used to write in WML Web page. WML is based on its XML-like syntax and scriptness. Anyone who has used HTML will have no problem learning WML. Many tags and attributes are the same, and there are not many tags. WML allows developers to develop dynamic content, although for this article we will use PHP as the dynamic language.
WML Basics
In WML you can use many subpages ( called "cards'') in a WML page (called a "deck"). Each WML card acts like content that is displayed on the web page. The following will be an example of our .wml page. On my Server, I Saved this file in ~ /wireless/home.wml

My first test page

Unlike HTML, if you do not colse tags, such as , your code will be incorrect. This example will generate a simple test message "My first A test page".
Configuring Apache
Okay, now the fun part. In order for apache to catch wireless devices accessing your server, you need to create your httpd.conf (mine is located in /etc/httpd/conf/) file, I use PHP3 therefore all changes will be logged. Before you start, you can backup your httpd.conf file, just in case :)
Step 1: First, we need the AddType function to add a new MIME type. You need to go into the Script where you define php. It will look like this:

AddType application/x-httpd-php3 .php3 .php .phtml
AddType application/x-httpd-php3-source .phps

To Change to:

AddType application/x-httpd-php3 .php3 .php .phtml .wml
AddType application/x-httpd-php3-source .phps

This will Use PHP compiler in all .wml pages.
Step 2: Remove Mark(Uncomment)apache Load Module and Add Module
Change:
#LoadModule rewrite_module modules/mod_rewrite.so
#AddModule mod_rewrite.c
Into:
LoadModule rewrite_module modules /mod_rewrite.so
AddModule mod_rewrite.c
Step 3: Use apache mod_rewrite module (only applicable to version 1.2+). Using this, you can instantly rewite the requested URL (when the conditions are met). You need to put this piece of code on the web page bottom.
RewriteEngine On
# Catch most WAP browsers
RewriteCond %{HTTP_ACCEPT} text/vnd.wap.wml [OR]
# WinWAP, WAPjag
RewriteCond %{HTTP_USER_AGENT} wap [OR]
#Nokia emulators (sdk)
RewriteCond %{HTTP_USER_AGENT} 7110
# Rewrite to where your wireless page is located
RewriteRule ^[./](.*)$ /home/mydirectory/wireless/home.wml [L]
Now you need to restart the apache server.
Generate your first wireless WML/PHP web page
Ok, now that we have everything ready, let's create our first web page. For this to work properly, you need to send the correct header information.
# Send the header information

header("Content-type: text/vnd.wap.wml");
?>
# put in the wml code

My first test page

You just finished your The first "simple" wireless web page. Now, let's try harder and do something harder.
You need to check your WAP compatible website device. I use the Phone.com Software Development Kit, which includes UP.Simulator, to inspect my wireless web pages. Select a different phone and see what their wireless pages look like when viewed through different devices.
