Question : Using querystrings with PHP

Hello,

I used to program in ASP all of the time but never PHP.

Assume the following is a static HTML page. What would the page look like in PHP to allow the content to be changed based on the querystring (i.e. variable X)?

Assume the URL is:  www.domainname.com/index.php?x=1


<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3c.org/TR/1999/REC-html401-19991224/loose.dtd">
<HTML>
<HEAD>
<TITLE>Title Goes Here</TITLE>
</HEAD>
<BODY>
<P>Hello world!</P>
</BODY></HTML>

I want the .php page to have an array that's defined with the following values:

1="Hello blue world!"
2="Hello red world!"
3="Hello green world!"
4="Hello purple world"

If a querystring exists and has a value found in the array, then it will display one of the array values shown above. If it's not found, then it will display "Hello world!".

What does the final PHP code look like (including any tags needed to "initiate" PHP like ASP's <% %> tags)? In other words, please supply code that starts with <!DOCTYPE...  and ends with whatever ending tag is needed at the end of the php page.

I appreciate your help!

Best regards,
Dan

In the switch() statement, add a "default:" statement just like the "case:" statements.
See http://php.net/manual/en/control-structures.switch.php
