First Page Using PHP

Today We will see that how to write first PHP enabled Program and test that on Browser !

Basic Thing Before write a program in PHP.

You required a Server like Apache or any other with PHP configuration.

You Should Create the PHP file in "DOCUMENT_ROOT" for XAMPP (htdocs), for WAMP(WWW ), for IIS(WWW) and so for. Directory as PHP.ini are configured.

Start to write a PHP Script

File name: Hello.php

<html> <head> <title> My First PHP Program! </title> </head><body><?php

/*PHP Script Start Here.*/

echo "Welcome to PHP!"; /* This statement print the Message Welcome to PHP! */?></body><html>

Then open start the service and then Open http://127.0.0.1/Hello.php or http://localhost/Hello.php

Output will Display like this..

Code in Editor.

Output on Browser.

In output in Browser Picture 1: Title of the Page

2: Address in which your php is save (DOCUMENT_ROOT/blogs)

3:Output of PHP Script!

If you try to see the source of the page in Browser the PHP Script look like test.

View Source Window in Opera.

Highlighted Part the Main PHP Script <?php echo "Welcome to PHP!" ?>

After Process by Apache Server the Script become "Welcome to PHP!".

If output is display like below code that means your PHP Configuration in not Set Correctly to do that and restart the server and then try.

 <html>
 <head>
 <title>PHP Test</title>
 </head>
 <body>
 <p>Hello World</p>
 </body>
 </html>

Install PHP, MySQL, Apache and PHPMYADMIN..

Hello Friends,
Before Write a PHP program it is necessary to configure the PHP with any Server like Apache or IIS or any other by using which it may possible to access the page.

Today We will see that how to install PHP and Apache..

There are two method to install the web server setup
First Method

Download the PHP Click Here.
Download Apache to Click Here.

Now Extract these .zip files and place in the C:/Apache and Configure Environment Variable.

Second Method

Download XAMPP (consist of Apache, MySQL, PHP, PHPMyAdmin). Click Here.
Download WAMP (Windows Apache, MySQL, PHP). Click Here

According to me XAMPP is best because it consist with all the required software setup for the web server designing and hosting.

XAMPP and WAMP are .exe (executable file) it do all task automatically so not any configuration required after install directly after finish the installation, just start the service of Apache by clicking on Start.

Interface of XAMPP

After start the service click here. or click here.

Hope so that you understand it if having any problem related to setup of XAMPP/WAMP or PHP and Apache to write the comment below in comment box.
