PHP Introduction - Free web development Tutorial



Introduction PHP

PHP is a server scripting language which is widely used to make dynamic web pages. A free scripting language. Easy to use in your web server for dynamic pages.

Example of PHP code:

<!DOCTYPE html>
<html>
<body>

<?php
echo "I am a php web developer!";
?>


</body>
</html>


inside HTML code we can use php code like above. Starts with <?php  end with ?>.

How to run php file?


                                                If we use php code in a page, to run that page we need to save as .php extension. Example “example.php”.

                                                We cannot run php normally as like HTML. We need a server software. In this example I am using Apache server. I will demonstrate how to run Apache server by Xampp software to run local host server.


I am using this software: Xampp software V3.2.2

You can download here and install it.
In server normally first page should be filename index.*.  if it is HTML index.html and if it is php web page the file should be index.php. Now create any folder to save this index file into a folder. Here I am creating a folder named “yourweb” into the folder “/xampp/htdocs” so the path of the index file “/xampp/htdocs/yourweb/index.php” . Code of index.php is 



<!DOCTYPE html>
            <html>
            <body>

            <?php
           echo "I am a php web developer!";
           ?>


           </body>
           </html>



Type this code in a text editor and save the index.php file into  “/xampp/htdocs/yourweb” folder.
Ok. Saved file. Now how we should run this file in web browser. Run xampp control panel in start menu. And click start “Apache” and “MySql” to run Apache server in local host.
Then you type the browser http://localhost/yourweb and enter now your index.php file will be open in your browser.
Like Below.


Output of index.php:
