IIS redirector – application request routing

A great thing with apache webserver is that you can redirect HTTP requests to another place within the site or even hosting local port, well with IIS you can achieve the same with Application Request Routing.

It is a great add-on that really empowers the admin users to achieve allot more “fun” things with IIS.

Method – Add Two numbers

This tutorial is using the same base code as Add two numbers, but with using the function addtwo, this takes two parameters $a and $b which are both set to 0 as the default value and returns the two values added together. The answer part of the web page uses the function to add the two numbers together.

The source code

       PHP - Add two numbers
Answer :

save as addtwonumbers_function.php, this program will function the same as the previous tutorial apart from the inner working will call the method. The method programming allows for one method to be called multiple times, e.g. Within the example above there could be a method that was 5 lines in length and instead of writing the same 5 lines each time, you just write a method that is called.

Add two numbers

This tutorial will add up two values that have been entered within the web page, I am going to use the web page functional aspects rather than the command line interface because php is mainly used within websites.

The web page itself is using a form tag, this form tag allows for the web page to post data back to the server, where the php will use the posts ($_POST) array ( []).

The source code is

       PHP - Add two numbers
Answer :

if you save that as addtwonumbers.php within the php website configured directory and then open up that page via a web browser (e.g. http://localhost/addtwonumbers.php, localhost means the local pc, just like is the local ring e.g the pc itself to talk to itself via an IP).

Just for completeness, this is the command line interface code.

Read/Write Files

This is a tutorial on how to open and write files with PHP, of course there is always different ways to accomplish the same task within programming languages.

Fopen will open up a file, the secod parameter is who to open the file, r = read, w = write.

$readin = fopen("countrys.txt", "r");

The while loop will set the variable $county equal to a line from the input file, the fscanf will scan a file with the second parameters requirements, the ‘[^\n]’ means anything that is not(^) a return character (\n).

while ($county = fscanf($readin, "%[^\n]")) {

Fwrite will output to the output file handler (the $output created with fopen), with the text in the second parameters

fwrite($output, "insert into country(place) values (\"$county[0]\");\n");

NOTE: the { } are the begin and end of a code structure, e.g. While begin; do something; end;

This is the code

if you save that as phpreadfile.php. and also create a countrys.txt file with what ever text you like, e.g. United Kingdom

United States etc.

The output of the program (php phpreadfile.php) will display each line that is read from the input file and the output file will have some other text in it, for demonstrating purposes, have done some sql code.

Hello world

This is the hello world for the php tutorial section. PHP is another Object Orientation language, to get php, if you download it from PHP.NET and you are able to use with Apache or with MS Tnternet Information Services IIS.

Once you have php installed, if you save this

as phphelloworld.php within the correct directory for the php engine to use the file.

Once you point your browser to the file e.g.

and the output will be “Hello World!”;

Hope that helps 🙂
