Why You Should Create PHP Powered Websites and How?
PHP :Hypertext Preprocessor is very useful, dynamic scripting language. You can create a simple website to powerful web application with PHP. If you are just beginning to get into web design and development you should consider learning it.
Let’s start with little introduction. PHP (originally stood for personal home page) is a server side scripting language, which means it resides on the server. You do not have to install PHP on your computer to view PHP scripts. Therefore, it is faster and better to work it. Whereas, if the javascript is disabled on the client computer, they will not be able to view the whatever script it is running on the web page. However, let’s not just assume one is better than the other, but both of them has their uses. You can embed PHP directly into the HTML page or create separate pages page with PHP extension. You do not even have to be a ninja coder to use the basic PHP functions. If you understand the basic, you can pretty much take it from there.
Why Create Webpage Using PHP?
The best thing I like about PHP is the ability to change webpage content dynamically. For example: let’s say your client wanted ten pages and you coded in the pages in HTML for using the usual header, content , footer layout. So, after you finsished coding all the page, you client says they want to change the logo or header content. You would have to go to individual page and change it. If you used PHP to create the page you would just change the header.php file and of course you would have to included the header in the all the pages. If you see the example below it will be more clear. You will need to install MAMP or WAMP to test PHP pages locally. If you do not how here is a guide for Mac and Windows.
You can take look at the demo of the two PHP pages created using the following method
We will start by creating an HTML page then just change it into PHP. So, here is the HTML layout
<html> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <title>PHP </title> <link rel="stylesheet" href="style.css" type="text/css" media="screen"/> </head> <body> <div id="wrapper"> <div id="header"> <h2>This Header </h2> </div> <div id="content"> <h2>This is First Page</h2> </p> </div> <div id="footer"> <h2>This footer </h2> </div> </div> <!-- end wrapper --> </body> </html>
Here is how the PHP files will be formatted
First, we will create header.php. Copy from <html> to <div id=”header”> <h2>This Header</h2> </div> to a new page and save it as a new page as header.php
Everything between content div will be inside index.php. We can later uses this PHP file to for more pages by duplicating it.
Next, is the footer. This is end of the page.
We need to to add all this three file into one. To combine this three file we will be using PHP include functions . This function includes one PHP file into another. Here is how we will both header and footer inside the index file:
On the beginning for index.php
<?php include("header.php"); ?>
At the end of the index.php file we add
<?php include("footer.php"); ?>
That is it. We have created our web page with PHP. Now, let’s say you want to create another page, you can just copy paste the index.php file and change the just the content. If you wanted to change something in the header, content or footer , you will just make change in the individual files you will not need make changes to each file. This was just most basic use of PHP , if you are planning to extend you knowledge on PHP we will add some links at the end of the post, where you can learn more PHP.
